Choosing the Best Measure of Center and Variability

This lesson teaches how to choose the best measure of center and variability by comparing each measure to data in real-world contexts. It covers calculating range, IQR, and identifying outliers. Through examples like rainfall data, basketball scores, reading time, and video game spending, the lesson demonstrates when to use mean, median, or mode. It emphasizes the importance of understanding data variability and choosing appropriate measures for accurate representation.
