10 hours

Construct and use parallel box plots, including identifying possible outliers, to compare datasets in terms of median, spread (range and IQR) and outliers to interpret and communicate the differences observed in the context of the data. 1 interactive
outliers (identifying): Q1 − 1.5 × IQR ≤ ≤ Q 3 + 1.5 × IQR where Q1 is lower quartile and Q 3 is upper quartile
Compare datasets in terms of mean, median, range, IQR and standard deviation, interpret the differences observed in the context of the data, and report the findings in a systematic and concise manner.
