Final answer:
The correct formula for converting absolute frequency to relative frequency is 'Relative Frequency = Absolute Frequency / Total Frequency'. To find cumulative relative frequency, you sum up all the previous relative frequencies to the current one.
Step-by-step explanation:
The formula to convert absolute frequency to relative frequency is given by:
Relative Frequency = Absolute Frequency / Total Frequency
This formula enables you to determine how often a certain event occurs in comparison to the total number of events. For example, if you have the absolute frequency of an event as 15 and the total frequency of all events is 100, to find the relative frequency, you would perform the calculation: 15/100 = 0.15. This means the relative frequency is 15% or 0.15 as a decimal.
To calculate cumulative relative frequency, you add the relative frequencies of all the preceding categories to that of the current category. For instance, if the first row in a table has a relative frequency of 0.15, and the second row has a relative frequency of 0.25, the cumulative relative frequency for the second row would be 0.15 + 0.25 = 0.40, and so on for the subsequent rows.
