In this activity pupils calculate the median and mean of three data sets and consider whether mean or median is the better measure of location in each case. This prompts class discussion about the impact of outliers in a data set. A number of other discussion points may arise - see notes.
This activity could be used at the start of a lesson on skewness. A word copy is attached for editing if required.
