Statistical Analyses of Variability

Project Overview

This primary source RWLO is intended to have students explore the variability of data from different populations. Students will access the United States Department of Labor Bureau of Labor Statistics website. Recent past price data will be gathered from the Consumer Price Index (CPI). Students will then use the Coefficient of Variation statistic to compare yearly variability of various consumer items.

This RWLO is for use in a beginning Statistics course after students have been introduced to the standard deviation.
