What is Cumulative Frequency

In the next maths videos I will explain what Cumulative Frequency is. We will look at a Cumulative Frequency Graph and find the median. In the second video we will construct our own Cumulative Frequency Graph. Make sure to study the free resources carefully during your maths revision and pass your next maths exam!

What are the Lower Quartile, Upper Quartile and Inter-Quartile Range?

You understand now what Cumulative Frequency is and therefore it is time to answer a Past Paper Question. Have a look at the next example question which is a typical question you can expect on your IGCSE GCSE maths exam. I will explain to you what the lower and upper Quartiles are and how to find the Inter Quartile Range. I will also explain how to find the median. Let me know on the forum of this website if you still don't understand Cumulative Frequency. I will help you with your maths and make some more example questions for you. Good luck and have fun!
