How to Calculate Averages from Group Frequency Tables

The video tutorial explains how to calculate averages from data in a grouped frequency table. It covers the mean, median, and mode, using an example of otter weights. The tutorial details how to identify the modal class, determine the median class, and estimate the mean. It emphasizes the importance of understanding the process and practicing to master these calculations.
