$$1$$. 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.
Count the tally marks to determine the frequency of each class. The relative frequency of a data class is the percentage of data elements in that class. The relative frequency can be calculated using the formula , where is the absolute frequency and is the sum of all frequencies. is the sum of all frequencies. In this case, . The relative frequency can be calculated using the formula .
