This document shows the step-by-step work of calculating the mean of a data set using a frequency table. It lists scores from 2 to 8 with their corresponding frequencies. It fills in the fx column by multiplying each score by its frequency. It then calculates the total fx by adding these values, and calculates the total frequency by adding all the individual frequencies. Finally, it divides the total fx by the total frequency to find the mean, which is 5.4.
