Measures of Central Tendency and Spread

This video tutorial explains how to calculate measures of central tendency and spread using a sample of highway mileage data from eight car models. It guides viewers through entering data into Google Sheets and calculating the mean, median, mode, standard deviation, and range. The video provides step-by-step instructions and concludes with a summary of the results.
