What you need to know:
In a cumulative frequency table, the frequencies are added up as you go along – i.e. rather than a frequency table which tells you “how many data points were recorded which had that value (or was in that group of values)”, a cumulative frequency table tells you “how many data points were recorded which had up to that value (or up to the highest point in that group of values)”. Constructing a cumulative frequency table is straightforward, just add up the appropriate values in the frequency table. The main focus of this topic is on your ability to construct cumulative frequency diagrams and use them.
You should know how to plot cumulative frequency data onto a graph, including important facts like plotting the individual values at the upper boundaries of each group, when the data is grouped. For example, if there is a group 170 – 180, measuring height to the nearest cm, the top boundary of that group is 180.5. Furthermore, your line should be a smooth curve, and will typically form a character “S” shape that you will recognise after a few practices of this.
