How to find the Median with a Cumulative Frequency Graph
Learn how to construct a Cumulative Frequency Graphs and how to find the Median with a Cumulative Frequency Graph. In the next videos I will explain to you how you can construct a Cumulative Frequency table by looking at a frequency table. I will also explain how you can find the median when looking at a Cumulative Frequency Graph. In the second part you will find out what Quartiles are and how you can calculate the Inter-Quartile-Range by looking at a Cumulative Frequency Graph. It is very like you will get a question about Cumulative Frequency on your IGCSE GCSE maths exam so study the example questions carefully and let me know if you need more help with your maths.
