Only the Grouped Frequency Table survived ... can we help Alex calculate the Mean, Median and Mode from just that table?The answer is ... no we can't. Not accurately anyway. But, we can make estimates.Estimating the Mean from Grouped DataSo all...
Grouped frequency tables are very useful for picturing larger amounts of data. However, they are not ideal for finding the mean, median, and mode of data because we can't tell what the actual original raw data is from a grouped frequency table. Therefore, we will mostly be using categorica...

The “Mode” is the simplest Grouped Average to find. It can be read straight from the Frequency Table, or straight from the Graph. Image Copyright 2013 by Passy’s World of Mathematics Sometimes we have more than one Group which is the most popular. ...
Compute the meanMean for a Frequency Distribution:The mean for grouped data is calculated from the frequencies and the midpoints of the classes. Therefore, for its calculation, the frequency distribution table must be completed at least up...
