Free frequency table GCSE maths revision guide, including step by step examples, exam questions and free worksheet.
If we have collected a lot of data, we might display it in a frequency table. We need to be able to construct a frequency table and know how to interpret and use one to solve problems, such as calculating the mean, median, mode and range of the data.
Complete the cumulative frequency column in the table. Draw a cumulative frequency graph for this information. The table shows information about the number of hours that 260 students spent revising for an exam. Complete the cumulative frequency table. On the grid on the following page, draw a cumulative frequency graph for your table. (2)
The cumulative frequency graph gives some information the times it took people to complete a challenge. Find the median time. Find the number of people who took longer then 80 seconds to complete the challenge. ............................. (1) frequency table shows the weight, in kg, of some cats.

Cumulative Frequency. Cumulative frequency is the number of times that anything up to and including that value (or group of values) appeared. You will need to be able to work out the cumulative frequency as well as use this to plot a cumulative frequency graph.
Example: A biased coin is flipped 500 times. The relative frequency of landing on heads is calculated to be 0.65. How many times did the coin land on heads? Apply the formula for relative frequency, identifying the relative frequency and number of trials from the question: 0.65 =
