just a running total of frequencies. But it is also a very useful tool
to understand a set of data. A cumulative frequency curve lets you
easily read off estimates for the median and quartiles even when faced
with a large amount of data!

Learn all about cumulative frequency, the median and the interquartile range
with this colourful interactive tool!

Enter raw data, complete a frequency table or and complete the
cumulative frequency table, and then plot the curve(s).

A set of introductory videos is provided to help you understand how to create
and interpret cumulative frequency curves, and you can load the sample data

understand!
