A frequency table of grades has five classes (A, B, C, D, F) with frequencies of 6, 16, 19, 5, and 4
respectively. Using percentages, what are the relative frequencies of the five classes?
The relative frequency of any category is the fraction (or percentage) of the data values that fall in that
category. The formula for relative frequency as a percentage is given below.
frequency in category
total frequency
x 100%
The sum of the percentages should be 100%, with a small discrepancy allowed for rounding errors, so a
sum such as 99% or 101% is acceptable.
The total frequency is 6+16+19+5+4= 50.
Substitute frequency in category A = 6 and total frequency = 50 into the formula to find the relative
frequency as a percentage of category A.
relative frequency of category A =
