cumulative frequency - Waldomaths


compare the cumulative frequency graph for various (10) standard and other data shapes

also compare these with the related boxplot

frequencies can be varied by dragging the red dots on the vertical axis - to see the effect on the cumulative frequency curve

questions can be asked about e.g. the frequency distribution from the cumulative frequency data and graph or the cumulative frequency graph from the boxplot (by clicking boxes on or off at the bottom)
