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.

What is the process to find the range of a data set?

Explain how to calculate the Interquartile Range (IQR) and its significance.

Why is it important to consider outliers when calculating the mean?

In the context of the rainfall data, which measure of center was chosen and why?

How does the variability of a data set affect the choice of the best measure of center?

What conclusions can be drawn from the basketball scores regarding the mean and median?

Describe the steps taken to analyze Christy's reading time data.
