Frequency Tables: Mean

The video tutorial explains how to calculate the mean from different types of data. It starts with the basic concept of mean as an average, calculated by dividing the sum of values by their count. The tutorial then covers calculating the mean from a frequency table, introducing the FX column to simplify the process. It also discusses estimating the mean from grouped data using midpoints and highlights that such calculations are estimates. The video concludes with additional tips and considerations for calculating mean from data with varying interval sizes.
