How to Estimate the Mean of a Data Set

The video tutorial explains how to estimate the mean time students spent doing sports using a frequency table. It covers calculating midpoints, multiplying them by frequencies, summing the products, and dividing by the total frequency to find the mean. The tutorial emphasizes the importance of accuracy in calculations and rounding the final answer to one decimal place. It also outlines the marking scheme for the problem.

How do you calculate the total frequency from the frequency column?

What is the final step to calculate the mean time spent by the students?

Why is it important to keep all decimal places in your calculations until the final answer?
