Calculators

Statistics

Generate one or more random number or random letter sets from a range of numbers or letters.

The random numbers or letters will be the random sample set. For Sample Size enter the value for the number of samples you need. For the Sample Range enter the range of values to randomly choose from. For example, to choose from 1 to 100 enter 1-100; to choose from a through m enter a-m or A-M.

If the sample size is greater than the sample range and duplicates are not allowed, the number of results will be limited by the range.

If you use the link in the "Share this Calculation" box a new randomized set will be generated every time the link is visited.

Generate a Random Number for a PIN.

To generate a 4 digit PIN without duplicate digits, choose Sample Size: 4, Sample Range: 0-9, and Allow Duplicates: no.

Example: 4 digit PIN without duplicates

To generate a 4 digit PIN with duplicate digits, choose Sample Size: 4, Sample Range: 0-9, and Allow Duplicates: yes. This will allow duplicates but will not necessarily produce duplicates every time. If you actually want duplicates you may need to try several times.
