Calculating Mean of Group Data using Direct Method

The video tutorial explains how to calculate the mean of grouped data using the direct method. It begins with an introduction to grouped data and the concept of mean as a measure of central tendency. The tutorial uses a survey example where students collected data on the number of flowers in pots. It explains how to organize data into class intervals, calculate mid values, and determine frequencies. The tutorial then demonstrates how to multiply mid values by their frequencies to find the product, and finally, how to calculate the mean using the formula for the direct method. The video concludes with a summary of the steps involved in the process.
