The number of entries of the data having their values lying in a class is defined as a frequency of the class.
The table in which the corresponding frequencies are written against each class is called a frequency distribution of given data.

Solution:
The number of students who have a certain type of blood group is called the frequency of those blood groups.
To make data more easily understable we write it in a table as given in attachment.
From the table(in the attachment) we observed that the higher frequency blood group i.e most common blood group is O and the lower frequency blood group i.e rarest blood group is AB.
