Relative frequency represents the number of times a value is repeated in any list of data out of the total data.

**Let us illustrate this with an example.**

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

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

Looking at the table, we find that 7 students in the class scored 70. We find the total number of students in the class by adding the data in the bottom row of the table.

We obtain:

$5+7+10+15+13= 50$ Students in the class.

According to the definition of relative frequency, this is in our case equal to the number of students in a class that received 70 parts of the total number of students in a class.

Therefore, the relative frequency sought is $7 \over 50$.
