Frequency

Frequency shows how often something happens (usually during a period of time). It is the number of times the data value occurs. These data values are often numbers, but they could also be qualitative data values, which are words. We represent the frequency of a data value by f.

Example: if five students got an A in maths, then the grade A is said to have a frequency of 5.
