Statistical frequency

Frequency actually represents the absolute number of times a value is repeated in a given list of data.

Let us illustrate this with an example.

The following table is presented with the data describing the scores of the students in a given class on the assessment conducted.

In other words, how many times a certain value is repeated (how frequent it is).

We are asked to find from the data in the table the frequency of the score$70$.

If we look at the table we find that $7$ students in the class received the grade $70$, and therefore this is also the frequency of the grade, i.e. the grade $70$ was repeated $7$ times in the class.
