Question

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

Answer 1

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
