Course
MATH 145 (Elementary Statistics)
Description
This module will help students better understand the relationship between the relative
frequency of an event and the probability of that event. It also helps students gain
further understanding of the law of large numbers and simulation. Students will use the
Int() and Rand() functions in Microsoft Excel (1) to simulate a large number of coin tosses,
(2) to simulate a large number of rolls of a single die, and (3) to simulate a large number
of rolls of a pair of dice. The relative frequencies of the possible outcomes are then
compared to the actual probabilities. By the law of large numbers, the relative
frequencies of the outcomes should be approximately equal to the actual probabilities.
Transferability
This module will transfer to any introductory statistics class, or any class that discusses
probability.
