Describing Data: Measures of Center and Spread

This lesson covers how to describe data using measures of center and spread, including mean, median, range, interquartile range (IQR), and mean absolute deviation (MAD). It explains how these measures are used in data analysis, particularly in line plots, histograms, and box plots. The lesson also includes a practical example using aluminum recycling data to demonstrate the application of these statistical measures.
