Describing Data (Part 1)

This lesson teaches how to describe a data set by identifying key statistical measures such as the maximum, minimum, range, mode, and median. Using a survey conducted by Sam, who asked 10 students about the number of pets they have, the video explains how to determine the maximum and minimum values, and how to calculate the range by subtracting the minimum from the maximum. The lesson emphasizes understanding these basic statistical concepts through practical examples.
