Right Answer is: C
SOLUTION
Cumulative frequency is used to determine the value that lies above or below a particular value in a data set. It is calculated by using the frequency distribution table.
It is calculated by adding each frequency in the frequency distribution table to the sum of its above values. The last value is always equal to the total number of observation because all frequencies have been added already.
