Answers to Questions

How to make a random sample/selection?

Enter elements to sample and the number of items to select, the program will generate the list of winning items randomly. This generation is done without bias and uses a pseudo-random generator.

The list of items can be given in 2 formats: either one item per line, or all item at once but, in this case, items must not contain spaces.

What is a random sample without replacement?

Without replacement, an item cannot be selected more than once in a draw. It is the case on most random selection processes.

What is a random sample with replacement?

With replacement, if multiple items have to be selected, then each item is replaced in the item list to select and thus, can appear more than once.

How to generate a random number?

From a lower limit (minimum) and an upper limit (maximum), the software generates a number automatically. The program is limited to natural integershref.

How to generate groups of elements?

The software can generate groups depending on the group size or the total number of groups.

How to associate items from two groups of the same size?

The software can generate a bijection af a group 1 in a group 2. One has to input all two groups one after the other.

How to assign people for gifting each other's?

The software can assign to each person to another (distinct of itself), which is useful for Christmas gifting.
