# E-Math: Summary of Cumulative Frequency & Box Whisker Plot

I have previously written 2 posts:

E-Math: Drawing and Understanding of Cumulative Frequency Curve (Step by step working included)

In this post, I have used an examination question to illustrate how to draw a cumulative curve using the information from the cumulative table, how to use the curve to find median weight, how to find percentile.

E-Math: 5 Features of Box and Whisker Plot You Must Know

A summary is given on the essential parts of a Box and Whisker Plot. Do you know there's a difference between interquartile range and range? Do you know how to read the upper & lower quartile, how to read the media?

Both are under the big topic of Statistics which is the most fun chapter as it relates really closely to what we see everyday.

Have fun!
