Frequency Polygon, Cumulative Frequency and Box Plots

2000 pupils took a test, the frequency polygon shows their scores. Experiment with the values of a, b and c to alter the distribution. The cumulative frequency graph and box plot can be shown. The orange point can be moved to find the median and quartiles.
