$$1$$. Notice that the difference between the cumulative frequency and the relative frequency is only that in the case of the relative we must divide by the total number of data. This can help us avoid unnnecessary calculations. List exercises by: Absolute, relative, cumulative frequency and statistical tables.
The simplest way to express a frequency is in absolute terms. A relative frequency describes the number of times a particular value for a variable (data item) has been observed to occur in relation to the total number of values for that variable. The relative frequency is calculated by dividing the absolute frequency by the total number of values for the variable.
