Calculating Mean of Grouped Data Using Assumed Mean Method

The video tutorial explains how to calculate the mean of grouped data using the assumed mean method. It begins with an introduction to grouped data and the assumed mean method, followed by a problem statement involving the daily expenditure of 25 households. The tutorial then details the process of tabulating data, calculating mid values, and finding deviations using an assumed mean. It continues with calculating products and totals for frequency and deviation, and concludes with using a formula to find the mean expenditure. The video ends with a summary of the steps involved.

Describe the process of calculating the product of frequency and deviation (fidi).
