Cumulative frequency table - GCSE Maths Definition

A cumulative frequency table is a way of organising data to show the total number of items that fall below or within a certain value in a set of data. It helps students see how data builds up as they move through a range of numbers, by adding the frequency of each category to the sum of the frequencies of all previous categories. For example, if you are looking at the number of books read by students in a class, the table would show how many students have read up to a certain number of books. This table helps in understanding the overall distribution of the data and is handy for plotting cumulative frequency graphs, which are often used to find medians and quartiles in GCSE Maths.
