Oft-Asked Questions

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

What are random numbers?

Random numbers are sets of digits (i.east., 0, 1, two, 3, 4, 5, 6, 7, viii, 9) arranged in random order. Because they are randomly ordered, no private 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 procedure that produces random numbers. Any random procedure (east.m., a flip of a money or the toss of a die) tin be used to generate random numbers. Stat Trek'southward 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'southward 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 tin produce numbers that are truly random, Stat Expedition's Random Number Generator produces numbers that are virtually random. Stat Expedition's Random Number Generator tin can exist used for almost statistical applications (like randomly assigning subjects to treatments in a statistical experiment). Notwithstanding, 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 instance, if nosotros set the minimum value equal to 12 and the maximum value equal to 30, the Random Number Generator volition 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 Expedition's Random Number Generator allows Users to allow or forestall the same number from actualization more than in one case in the random number table. To permit indistinguishable entries, set the driblet-down box labeled "Permit duplicate numbers" equal to True. To preclude indistinguishable entries, modify the setting to False.

Essentially, allowing indistinguishable 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 ready of random numbers or repeats a particular sequence of random numbers. If the dropdown box labeled "Seed" is gear up to "None", the Random Number Generator will produce a different set up of random numbers each time a random number table is created. On the other paw, 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.

Notation: The ability of the seed to repeat a random sequence of numbers assumes that other User specifications (i.east., quantity of random numbers, minimum value, maximum value, whether indistinguishable values are permitted) are constant beyond replications. The use of a seed is illustrated in Sample Problem ane.

Warning: The seed adequacy is provided for Users every bit a short-term convenience. Information technology allows a User to regenerate the aforementioned set of random numbers tomorrow as he/she generated today. All the same, there is a risk to relying on the seed adequacy to recreate a item random number table. From fourth dimension to fourth dimension, 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 mode to "save" a random number table is to print it out. The algorithm was terminal changed on three/11/2022.

Sample Problem

A academy is testing the effectiveness of two different medications. They have x volunteers. To conduct the written report, researchers randomly assign a number from 1 to two to each volunteer. Volunteers who are assigned number 1 become Handling 1 and volunteers who are assigned number 2 get Treatment 2. To implement this strategy, they input the post-obit settings in the Random Number Generator:
- They desire to assign a number randomly to each of x volunteers, and so they need 10 entries in the random number tabular array. Therefore, the researchers enter 10 in the text box labeled "How many random numbers?".
- Since each volunteer will receive ane of two treatments, they prepare the minimum value equal to i; and the maximum value equal to two.
- Since some volunteers will receive the same treatment, the researchers permit duplicate random numbers in the random number table. Therefore, they fix the "Let duplicate entries" dropdown box equal to "True".
- And finally, they fix the Seed value equal to 1. (The number ane is not special. They could have used any positive integer.)
Then, they hit the Calculate button. The Random Number Generator produces a Random Number Table consisting of 10 entries, where each entry is the number 1 or two. The researchers assign the handling indicated by the first entry to volunteer number 1, the handling indicated by the 2nd entry to volunteer number 2, and then on.
Using this strategy, what treatment did the starting time volunteer receive? What treatment did the tenth volunteer receive?

Solution:

This problem tin be solved by recreating the exact Random Number Table used by the researchers. By inputting all of the aforementioned entries (especially the same Seed value) that were used originally, we can recreate the Random Number Table used by the researchers. Therefore, nosotros do the following:
- Enter 10 in the text box labeled "How many random numbers?".
- Prepare the minimum value equal to 1 and the maximum value equal to 2.
- Set the "Allow indistinguishable entries" dropdown box equal to "Truthful".
- Set the Seed value equal to 1.
And so, we hit the Summate button. This produces the Random Number Table shown below.

10 Random Numbers

1 1 ane ii 2 1 1 2 i 2

Specs: This tabular array of ten random numbers was produced according to the post-obit specifications: Numbers were randomly selected from within the range of ane to 2. Duplicate numbers were immune. This table was generated on 10/28/2022.

From the table, we tin can see that the first entry is "1". Therefore, the commencement volunteer received Treatment ane. And the second entry is also "1". Hence, the second volunteer also received Handling 1. Then on. The tenth volunteer received the 10th number in the listing, which is "two". So the tenth volunteer received Treatment 2.

We would like to survey 500 families from a population of 20,000 families. Each family unit has been assigned a unique number from 1 to 20,000. How can we randomly select 500 families for the survey?
Solution:

We input the following settings in the Random Number Generator:
- We desire to select 500 families. Therefore, nosotros 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, nosotros don't want duplicate random numbers in our random number table. Therefore, we set the "Allow duplicate entries" dropdown box equal to "False".
Then, we hit the Calculate button. The Random Number Generator produces a Random Number Table consisting of 500 unique random numbers between 1 and 20,000. We will survey the families represented by these numbers - a sample of 500 families randomly selected from the population of xx,000 families.
