Practise reading and comparing data displays using medians, quartiles, IQR, class midpoints and positions in ordered data.
How this is tested
- calculate medians and IQR from ordered values, box plots or grouped intervals using correct positions
- explain why a median is unchanged when new values are placed either side of the middle of the data set
- compare two distributions using medians and IQR, making the conclusion match the given context
