Exploring Dot Plots and Stem and Leaf Plots

The video tutorial explains how to calculate statistical measures such as range, mean, median, and mode using dot plots and stem-and-leaf plots. It provides step-by-step instructions for each measure, including using a calculator for the mean. The tutorial covers two examples, demonstrating the process of finding these measures from given data sets.

What is the range of the dataset if the highest score is 12 and the lowest score is 8?

• 4

• 5

• 6

• 3
