The video tutorial covers measures of central tendency, including mean, median, and mode. It provides examples of calculating these measures on a data set and explains how to code a set to find the mean. The tutorial also discusses the impact of adding or multiplying constants to data sets on the mean. Finally, it explores central tendency in grouped data, including estimating the mean and median using midpoints and linear interpolation.

Describe how adding a constant to each data point affects the mean.

What is the method for estimating the mean from grouped data?

How do you find the median using linear interpolation in grouped data?
