Random Number Generator

Use the Random Number Generator to create a list of random numbers (up to 10,000 numbers), based on your specifications. The numbers you generate appear in the Random Number Table .

For help in using the Random Number Generator, read the Frequently-Asked Questions or review the Sample Problems .

  • Enter a value in each of the first three text boxes.
  • Indicate whether duplicate entries are allowed in the table.
  • Click the Calculate button to create a table of random numbers.

Note:   A seed value of "None" produces new random numbers with each computation. Any other setting produces the same random numbers, until the seed value is changed. The seed allows you to recreate the same random number table time after time.

Random Number Table

Frequently-asked questions.

Instructions: To find the answer to a frequently-asked question, simply click on the question.

What are random numbers?

Random numbers are sets of digits (i.e., 0, 1, 2, 3, 4, 5, 6, 7, 8, 9) arranged in random order. Because they are randomly ordered, no individual digit can be predicted from knowledge of any other digit or group of digits.

What is a random number generator?

A random number generator is a process that produces random numbers . Any random process (e.g., a flip of a coin or the toss of a die) can be used to generate random numbers. Stat Trek's Random Number Generator uses a statistical algorithm to produce random numbers.

What is a random number table?

A random number table is a list of random numbers. Stat Trek's Random Number Generator produces a list of random numbers, based on the following User specifications:

  • The quantity of random numbers desired.
  • The maximum and minimum values of random numbers in the list.
  • Whether or not duplicate random numbers are permitted.

How "random" is Stat Trek's Random Number Generator?

Although no computer algorithm can produce numbers that are truly random, Stat Trek's Random Number Generator produces numbers that are nearly random. Stat Trek's Random Number Generator can be used for most statistical applications (like randomly assigning subjects to treatments in a statistical experiment). However, it should not be used to generate numbers for cryptography.

What are the minimum and maximum values in the Random Number Generator?

The minimum and maximum values set limits on the range of values that might appear in a random number table. The minimum value identifies the smallest number in the range; and the maximum value identifies the largest number. For example, if we set the minimum value equal to 12 and the maximum value equal to 30, the Random Number Generator will produce a table consisting of random arrangements of numbers in the range of 12 to 30.

What does it mean to allow duplicate entries in a random number table?

Stat Trek's Random Number Generator allows Users to permit or prevent the same number from appearing more than once in the random number table. To permit duplicate entries, set the drop-down box labeled "Allow duplicate numbers" equal to True. To prevent duplicate entries, change the setting to False.

Essentially, allowing duplicate entries amounts to sampling with replacement ; preventing duplicate entries amounts to sampling without replacement .

What is a seed?

The seed is a number that controls whether the Random Number Generator produces a new set of random numbers or repeats a particular sequence of random numbers. If the dropdown box labeled "Seed" is set to "None", the Random Number Generator will produce a different set of random numbers each time a random number table is created. On the other hand, if a number is selected for "Seed", the Random Number Generator will produce a set of random numbers based on the value of the Seed. Each time a random number table is created, the Random Number Generator will produce the same set of random numbers, until the Seed value is changed.

Note: The ability of the seed to repeat a random sequence of numbers assumes that other User specifications (i.e., quantity of random numbers, minimum value, maximum value, whether duplicate values are permitted) are constant across replications. The use of a seed is illustrated in Sample Problem 1 .

Warning: The seed capability is provided for Users as a short-term convenience. It allows a User to regenerate the same set of random numbers tomorrow as he/she generated today. However, there is a risk to relying on the seed capability to recreate a particular random number table. From time to time, Stat Trek may change the underlying random number algorithm to more closely approximate true randomization. A newer algorithm will not reproduce random numbers generated by an older algorithm, even with the same seed. Therefore, the safest way to "save" a random number table is to print it out. The algorithm was last changed on 3/11/2022.

Sample Problem

  • They want to assign a number randomly to each of 10 volunteers, so they need 10 entries in the random number table. Therefore, the researchers enter 10 in the text box labeled "How many random numbers?".
  • Since each volunteer will receive one of two treatments, they set the minimum value equal to 1; and the maximum value equal to 2.
  • Since some volunteers will receive the same treatment, the researchers allow duplicate random numbers in the random number table. Therefore, they set the "Allow duplicate entries" dropdown box equal to "True".
  • And finally, they set the Seed value equal to 1. (The number 1 is not special. They could have used any positive integer.)
  • Enter 10 in the text box labeled "How many random numbers?".
  • Set the minimum value equal to 1 and the maximum value equal to 2.
  • Set the "Allow duplicate entries" dropdown box equal to "True".
  • Set the Seed value equal to 1.
  • We want to select 500 families. Therefore, we enter 500 in the text box labeled "How many random numbers?".
  • Since each family has been assigned a number from 1 to 20,000, we set the minimum value equal to 1; and the maximum value equal to 20,000.
  • Since we only want to survey each family once, we don't want duplicate random numbers in our random number table. Therefore, we set the "Allow duplicate entries" dropdown box equal to "False".

FAQ: Random Question Generators

Here are some common questions about random question generators.

What can you do with a random question generator?

You can use this tool for prompts to facilitate conversations and get to know someone. These tools are helpful for generating a random question of the day, as well as playing games like twenty-one questions, would you rather, and icebreakers.

How do online question generator tools work?

Question generators are a simple application that combine a user interface with a database of questions. The developers enter unique questions into the tool that can be themed toward topics like “couples” or “fun.” Then, users press a button that triggers a random mathematical calculation, which then pulls a corresponding question from the database.

What are some random question?

Here are some random questions:

  • What do you think about sushi?
  • Are walruses smarter than cows?
  • Would a modified-submarine work as a space shuttle?
  • How many donuts are eaten in the world each day?
  • Who played Batman best?

What is the weirdest question to ask?

The weirdest question to ask is “If you could go back in time and talk to one person, and that interaction would lead to the untimely death of one other person, and you aren’t allowed to wear socks for three years after unless they are blue, then which person would you talk to and when?”

What is the most random question?

The most random question you can ask is one that is created from a large database of random questions. For example, a data set of 100 would be 10x more random than a set of 10, and so on. Theoretically, the question would come from a data-set of infinity minus one.

20 Random Number Generator Interview Questions and Answers

Prepare for the types of questions you are likely to be asked when interviewing for a position where Random Number Generator will be used.

random number generator questions

A random number generator is a mathematical tool that is used to generate a sequence of numbers that are random and unpredictable. Random number generators are used in a variety of applications, including games, simulations and statistical sampling. If you are interviewing for a position that requires knowledge of random number generators, it is important to be prepared to answer questions about how they work and what their applications are. In this article, we will review some common questions about random number generators and how to answer them.

Random Number Generator Interview Questions and Answers

Here are 20 commonly asked Random Number Generator interview questions and answers to prepare you for your interview:

1. What is a random number?

A random number is a number that is generated by a computer program that is designed to appear as if it was generated by a random process.

2. Can you explain the difference between a pseudo-random number and a true random number?

A pseudo-random number is a number that is generated by an algorithm that appears to be random, but is actually deterministic. A true random number is a number that is generated by a physical process that is truly random, such as radioactive decay.

3. What are some examples of random number generators that can be used for data science?

Some examples of random number generators that can be used for data science include the Mersenne Twister, the Linear Congruential Generator, and the Blum Blum Shub.

4. How do you generate random strings in Python?

There are a number of ways to generate random strings in Python. One way is to use the random module, which provides a number of functions for generating random numbers. Another way is to use the string module, which provides a number of functions for working with strings.

5. Is it possible to use Excel’s RAND() function to generate a random number? If yes, then how would you go about using it?

Yes, it is possible to use Excel’s RAND() function to generate a random number. To do so, you would need to first enter the function into a cell. Then, you would need to specify the range of numbers that you want the function to choose from. Finally, you would need to hit the Enter key to generate the random number.

6. Why do we need to seed a pseudo-random generator?

A seed is necessary for a pseudo-random number generator because without it, the generator would produce the same sequence of numbers every time it is used. Seeding the generator with a value that is different each time ensures that the sequence of numbers produced is also different each time.

7. What does it mean to “seed” a random number generator?

Seeding a random number generator means to provide it with an initial value, known as a seed, from which it can generate a sequence of numbers. The seed can be any value, but it is usually a number or a string of numbers. Seeding a random number generator can be important in order to get reproducible results.

8. How many times should a pseudo-random number generator be seeded before each run?

A pseudo-random number generator should be seeded at least once before each run.

9. Is it possible to seed a pseudo-random number generator with an integer value? If yes, then how?

Yes, it is possible to seed a pseudo-random number generator with an integer value. This is typically done by using the srand() function in C++, which takes an integer value as an argument.

10. What are some popular software packages that provide random number generation functionality?

Some popular software packages that provide random number generation functionality include the GNU Scientific Library, the Mersenne Twister, and the Random Number Generator Library.

11. What is your opinion on the quality of the random numbers generated by these software packages?

I believe that the quality of the random numbers generated by these software packages is quite good. I have used them myself and have found them to be quite reliable.

12. Are there any special considerations or limitations that must be kept in mind when generating random numbers?

There are a few things to consider when generating random numbers. First, you need to decide what kind of distribution you want the numbers to follow. This will determine what algorithm you use to generate the numbers. Second, you need to decide how many random numbers you need. This will determine the size of the number pool that you generate. Finally, you need to make sure that the numbers are truly random. This means that they cannot be predicted or biased in any way.

13. What are some ways to ensure uniform sampling from a discrete set of values?

Some ways to ensure uniform sampling from a discrete set of values are to use a technique called reservoir sampling or to use a technique called the alias method.

14. Can you explain what the Monte Carlo method is?

The Monte Carlo method is a way of approximating a result by running a large number of simulations. This is often used in cases where it is difficult or impossible to obtain an exact answer, but where a close approximation is sufficient. For example, if you wanted to know the probability of a certain event occurring, you could use the Monte Carlo method to run a large number of simulations and then count the number of times the event occurred. This would give you a good approximation of the probability.

15. What is the best way to determine if a distribution is continuous or discrete?

The best way to determine if a distribution is continuous or discrete is to look at the function that is used to generate the numbers. If the function is continuous, then the distribution is also continuous. If the function is discrete, then the distribution is also discrete.

16. How can you tell if a given distribution has the property of being stationary?

A stationary distribution is one where the mean and variance are constant over time. One way to test for stationarity is to compute the autocorrelation function. If the autocorrelation function is zero at all lag values, then the distribution is stationary.

17. What are some common applications of random number generators in data science?

Some common applications of random number generators in data science include: – Generating random samples from a population – Performing Monte Carlo simulations – Creating random permutations – Generating random numbers for encryption

18. What is the purpose of using a logistic map in a random number generator?

The logistic map is a mathematical function that is used in order to generate a sequence of pseudo-random numbers. This function is often used in random number generators because it is relatively simple to compute, yet it can produce a long sequence of numbers that appear to be random.

19. What is the Fisher-Yates shuffle algorithm?

The Fisher-Yates shuffle algorithm is a method for randomly shuffling the elements of an array. The basic idea is to go through the array from end to end, swapping each element with a random element from the rest of the array. This ensures that each element has an equal chance of ending up in any position in the array.

20. How can you test whether a given random number generator is truly random or not?

There are a few statistical tests that can be used in order to test the randomness of a given number generator. One such test is the chi-squared test, which looks at the distribution of generated numbers in order to see if they fit a uniform distribution. Another test that can be used is the autocorrelation test, which looks at the correlation between successive generated numbers in order to see if there is any pattern.

    Using the randomizer

Using this list randomizer you can shuffle any list in random order. It uses strong cryptographic algorithms to generate random numbers which are then used in an algorithm for unbiased randomization of the list items (more on this below). The result is a truly randomly shuffled list consisting of the initial items.

To use the tool, simply enter a list of items of any sort, one item per row (copy/pasting from a spreadsheet works great). It could be a list of numbers, words, names, emails, countries, songs, tasks, and so on. This website uses a secure connection over HTTPS and does not store any of the information you enter in the field above, so the randomizer should generally be safe to use even for somewhat sensitive information, but it is best that you consult your information security officer if you have any concerns.

The easiest way to retrieve the randomized list is to select it all (Ctrl+A on a PC), and then copy it (Ctrl+C on a PC).

    How many items can the randomizer process?

The maximum number of items per list the randomizer will process is 100,000 . If your items contain a lot of text this number may be subject to further restrictions such as the maximum request size allowed, or the memory limit allotted to our scripts. If you run into such issues, consider replacing the items with short numerical item IDs before feeding them to the shuffler as a list.

    Example applications of the randomizer

A free online randomizer like this can have many possible uses. Here we list a few more common ones.

The classic way to randomly distribute players across teams in a sports game or board game is to randomly draw names out of a hat. Using the list randomizer you can spread players into two or more teams fairly and without bias. Simply enter all the player names and click "Randomize list". If you need two teams, select the first half of the shuffled names for team 1 and the second for team 2. A similar process can be followed for any number of teams as long as the total number of players is divisible by the number of teams to fill. The same logic can be used to distribute students for school group projects.

Despite the above examples, it is more convenient to use our dedicated random team generator which supports multiple teams easily.

If you have a number of names, emails, or identifiers of some sort, and you want to randomly sort them so that only the top 1, 5, 10 etc. receive an award, you can enter the list and randomize it to obtain the list of winners. If the awards are numbered from, say, 1 to 10, you can dole out the awards following the order of the shuffled list.

In case you need to distribute chores or tasks over a group of people or over several days simply list the chores or tasks and shuffle them with our software. Then start with the first on the list and proceed till the end. Similarly, you can randomize a list of your child's names to determine in what order they will do the dishes, sweep the floors, or throw out the garbage in the next few days.

If you are a schoolteacher, you may use this to randomly pick students for different home assignments, projects, etc. While a physical spinning wheel might be more fun, using an online list randomizer is easier.

In yet another scenario, you might want to shuffle a list of songs, books, games, or other things you want to get in random order. In this sense our tool can be used as a random order generator.

These are just several scenarios for using a list shuffler, but we are sure you can come up with many more.

    Is the randomized list truly random?

If your requirements for the randomness of the shuffle are high, you may be wondering if you can trust that our randomizer engine results in unbiased shuffles . Bias here has the technical meaning of 'systematically skewed'. In list shuffling a systematic skewness will be exhibited if items in a certain position in the initial list have an expected probability for ending up in a given position in the shuffled list which is different than the probability of ending up in any other position.

In order to check the randomizer unbiasedness , we devised a straightforward simulation , consisting of shuffling a list of 4 items 4,000,000 times. For simplicity, the four items were the numbers 1, 2, 3, and 4, fed to the randomizer each time in that order.

The results were collected and for each of the four possible positions we summed up the numbers that ended up there in the 4,000,000 simulations. This is the resulting histogram:

randomizer list shuffle simulation

As you can see, there is no bias towards any of the positions, each having a sum of approximately 1,000,000 out of the total sum of 4 million. A statistical goodness-of-fit test was conducted which resulted in a p-value of 0.86, firmly indicating conformity to the expected uniform distribution. As a further precaution we examined the distributions of ones, twos, threes and fours in all positions and found them to be uniformly distributed across them. Goodness-of-fit tests were performed for each of these and the results were again within the expected bounds, confirming that our randomizer produces truly random shuffled lists which should be safe to use in any application requiring robust randomness in the shuffle.

    Shuffling algorithm used in the randomizer

For this random list generator we employ the robust, efficient, and unbiased Fisher–Yates shuffle [1] , also known as the Knuth shuffle . In particular, we implement its modern variant (the initial algorithm was for pen, paper, and a dice!) as described in Richard Durstenfeld's 1964 work [2] . The algorithm was popularized by D.Knuth in his book "The Art of Computer Programming".

The random numbers required for the algorithm's application are generated using a cryptographic pseudo-random number generator (CPRNG) supplied by urandom, the Linux kernel's random number source.

    Randomizer vs. Randomiser

A brief note for those of you who might be confused and wondering as to the correct spelling of the word. Both are correct, however. 'Randomizer' is the American version while 'Randomiser' is the preferred spelling in British English.

random number generator questions

If you're looking to generate random numbers, you've found the correct website. Our Random Number Generator gives you several different options when you need to generate random numbers. The entire process is quite simple. First, pick the number of random numbers you need to be generated, then choose the number range you'd like the random number to be generated between. Once done, click the "Generate Random Numbers" button and they will instantly appear. You can determine a specific range of numbers or you can use one of the several set number generators. These include random numbers between 1 and 10, random numbers between 1 and 100, and random numbers between 1 and 1000. For those who may need to generate negative numbers, we also have the option of random numbers from -100 to 100.

There are a variety of reasons someone might need to use a randomized number generator. They have applications in a wide variety of fields including statistical sampling, cryptography, and computer simulation. For the purpose of visiting this page, however, it's more likely for a much less sophisticated reason. Below you can find some of the more common reasons people are looking to generate random numbers.

If you're having a contest and need to award a prize to a random person in the contest, this can be the perfect tool. Assign each entry a number and then use the random number generator to give you the winner. If you have multiple prizes to give away randomly, simply choose the number needed and click. By generating random numbers you ensure that the prizes are going to random entries so the contest is fair for all.

Choosing Order

If you have a group of people and you need to designate them into a specific order, one way this can be done is to assign each person a number. You can then use the tool to decide the order of each person in the group. For example, if you have 10 people that you need to have randomly lined up, you can assign each a number and then generate a list of random numbers for all ten in the numbers generator. The top number generated would place the person assigned the first spot to that place with the other people in the group moved to the appropriate places from there. This way the numbers generator gives each person a random position.

Picking Numbers

Often there's a reason that you need to pick a random number between a specific set of numbers. This can be done by using the pick your own number option.

Frequently Asked Questions

How random is this random number generator.

As random as we can make it! We use javascript's internal Math.random() function which returns a Psuedo-random number in the range 0 to less than 1. We then just transform that number into an integer. The internals are complicated but rest assured, these numbers are as random as it gets.

What is the minimum number you can use in your Number Generator?

There is no minimum number, you can use 0 or even a negative number. Currently only integers are supported but we'll be adding an option for floating numbers soon.

What is the maximum number you can use in your Number Generator?

The maximum number that you can use in the random number generator is 1000000000 (1 billion)

Do you have a Random Number Generator mobile app?

No, we don't have a mobile application, but our website is 100% mobile friendly.

Decimal Random Number Generator

What is a random number generator, decimal vs integer random numbers, how to use this random number generator with decimals, related omni calculators.

Omni's decimal random number generator will assist you in your math or programming tasks by producing as many uniformly distributed random decimal numbers as you need and from the range you need. In the article below, we will briefly explain what random and pseudo-random decimals are.

A random (or rather pseudo -random) number generator is an algorithm that outputs a sequence of numbers. These numbers should follow no discernible pattern , i.e., it should not be possible to predict the next number of the sequence.

Since there's an algorithm behind the generation procedure, these numbers are not truly random yet they are good enough for most applications. What our decimal random number generator produces is in fact a sequence of pseudo-random decimal numbers.

A decimal number is a number written in the base-10 system, i.e., the number system that is most commonly used nowadays. Examples of decimal numbers are 0.33, 2, 2.34 , etc.

A decimal number consists of a whole number part and a fractional part . For example, 2.34 has 2 as its whole number part and 0.34 as its fractional part. There is no whole number part in 0.33 , while 2 has no fractional part. The latter number can also be written as 2.0 . It is, in fact, an example of an integer , which is a decimal number with no fractional part.

When it comes to drawing random numbers , an important difference between integers and decimal numbers is that in every range [a,b] , there are finitely many integers but infinitely many decimal numbers . If we draw decimal numbers from any continuous distribution, in particular from the uniform distribution, then the probability of getting duplicates is zero .

Our random number generator with decimals is really straightforward to use:

  • Specify the range from which you want to draw.
  • Tell us how many numbers you want .
  • If you wish, you may adjust the precision, i.e., the number of decimal places .
  • Our decimal random number generator can sort the numbers it produced - just switch the Sort option to Yes .
  • Similarly, you can choose between List and Column output.

🙋 Enter 0 as Precision to produce integers with the help of our random decimal number generator.

Done with our random number generator with decimals? Here's a bunch of other Omni tools which can help you learn more about random numbers and probability:

  • Random number generator ;
  • Uniform distribution calculator ;
  • Dice roller calculator ; and
  • Probability calculator .

How do I generate a random number from a given range?

If you want to generate a random number from the interval [a, b] :

  • Generate a random number from the interval [0, 1] .
  • Multiply this number by (b - a) .
  • Add a to the result of Step 2.
  • That's it! What you got in Step 3 is a random number from [a,b] .

Can I express every integer as a decimal?

Yes , every integer can be expressed as a decimal number. In fact, there are two ways to do that: for example, the integer 2 can be expressed as 2 and as 1.999… (with the 9 repeating infinitely many times). In computer science, we would also consider 2.0 or 2.000 as different from 2 .

How do I obtain true random numbers?

Random numbers generated by computer algorithms are, in fact, pseudo -random: they do follow some pattern, yet a highly complicated one. To get a true random number, we can exploit various physical systems , in particular quantum systems.
