Distribution Maker

Stage: 5 Challenge Level: Challenge Level:1

The distribution maker allows you to make your own probability distributions and create random numbers from these. You can use this tool to experiment with distributions or to create your own bespoke random numbers.

Key points
  • You choose the possible values of X using the left pair of arrows to choose a starting number and the right pair of arrows to create an increment
  • Click on the up and down arrows to give the frequency of that result occurring.
  • The probabilities of each value and the mean of the distribution are given below.
  • For your distribution 100 random numbers will be created each time you press the 'Generate Numbers' button. The distribution of these numbers is shown in red, which you can hide by pressing 'hide sample'.

The NRICH Project aims to enrich the mathematical experiences of all learners. To support this aim, members of the NRICH team work in a wide range of capacities, including providing professional development for teachers wishing to embed rich mathematical tasks into everyday classroom practice.
