Calculating the mean from a frequency table
This Powerpoint consists of a variety of worked examples which demonstrate how we can calculate the mean by using the "fx" column. The lesson starts with students asked to calculate the mean of a large set of data. Next by placing the data into a tally chart it is easy to show how much quicker it is to calculate the mean when presented in this format rather than a list of numbers.
