Final answer:
To calculate the relative frequency, divide each frequency by the total number of data values.
Step-by-step explanation:
The correct method to calculate relative frequency is option A) Divide each frequency by the total.
To calculate the relative frequency, you need to divide each frequency by the total number of data values. This will give you the fraction or proportion of the number of times a value of the data occurs in the set of all outcomes to the total number of outcomes.
