There are many ways of organising data so that we can understand the data more easily. One of the ways of presenting data is with a frequency table. The word frequency means "how many" or "the number of" so a frequency table tells us how many of each item we have. Look at this video to see how we can create a frequency table.

Remember!

A frequency table is a table which show the "number of" or "frequency of" each item.
