IB Biology SL D3.2.15 Box-and-whisker plots
Practise reading box-and-whisker plots to estimate medians, maxima, percentages and outliers, then judge patterns in biological data sets.
How this is tested
- interpret medians, quartiles and whiskers to estimate values from plotted data
- determine proportions at or below a value using the position of the median or box
- evaluate overlap, outliers and spread when judging whether groups differ
