Countdown to Exams - Day 17 - Mean, Median, Mode, Range

Countdown to Exams - Day 17 - Mean, Median, Mode, Range

On day 17, we shift our focus to the Statistics topic looking at Mean, Median, Mode and Range. We take a look at how to calculate the three averages and when it might be necessary to calculate each average.

Mean - When you want to include all the data. Median - When you want to eliminate extreme values (outliers) from the data set. Mode - When you are dealing with categorical data (either Quantitative or Qualitative). Range  - Is not an average but a measure of spread.

In this video, Matt goes through how to calculate each average and the range.
