MATH 145 (Elementary Statistics)
Description
A calculator program will be used to graph binomial distributions for a given number of trials (n)
and a given probability of success (p). The program asks the student to enter n and p.
It then graphs the histogram of that binomial distribution.
The purpose is for students to discover (1) if p = .5, then
the distribution will be perfectly symmetrical, (2) if p < .5, then the binomial distribution will be
skewed right, and (3) if p > .5, then the binomial distribution will be skewed left.
Transferability
This module will transfer to any introductory statistics class or any class that discusses binomial probabilities.
