A frequency table of grades has five classes (a, b, c, d, f) with frequencies of 33 , 1111 , 1616 , 77 , and 22 respectively. what are the relative frequencies of the five classes

1.) Sum the items or the class' frequencies:

33 + 1,111 + 1,616 + 77 + 22 = 2859

2.) Divide each class' frequency by the total frequency:

a = 33/2859

=.012

b = 1,111/2859

=.389

c = 1,616/2859

=.565

d = 77/2859

=.027

e = 22/2859

=.008

3.) Therefore, the relative frequencies of each class are as follows:

a =.012; b =.389; c =.565; d =.027; e =.008
