Histograms
In this activity students examine real-life data, identify skew, and investigate the relationship between mean, median and mode for distributions with varying skew.
Identifying Skew in Histograms: Activity Sheet This handout shows three histograms and five questions relating to each. Students need to interpret the information shown in each histogram and identify how the skewness relates to the three averages. It could be attempted by students after a brief introduction to the topic.
Identifying Skew in Histograms: Teacher Notes This document provides an overview of the student handout and makes suggestions about approaches to teaching this topic. It points out that histogram two on the student handout may not be recognised as being symmetrical because students may be looking for near perfect symmetry.
