Graphs Binomial Distribution

Activity Overview

A probability function may be represented as a formula (usually an equation), a table or a graph. In this activity, you will use interactive graphs in TI-Nspire CAS to explore the effect that changing the value of a parameter (a number describing some characteristic of the distribution) has on the graph of that probability function.


The aim is for students to become familiar with the shape of the binomial distribution for a range of values for n and p, including comparisons of skew and standard deviation and expected value.


  • Binomial distribution
  • Skew
  • Mean
  • Standard Deviation

About the Lesson

Students explore graphs of the binomial distribution, looking at skew, mean, median, mode for a range of probabilities.
