Solution

frequency distribution : A frequency distribution is a representation, either in a graphical or tabular format, that displays the number of observations within a given interval.

It can be observed that 9students have their blood group asA, 6as B, 3asAB, and12 as O

Therefore the blood group of 30students of the class can be represented as follows:

Blood group Tally marksFrequency
A||||||||9
B|||||6
AB|||3
O||||||||||12
Total 30


Hence, The frequency distribution table for the data is the above table.

From the observation of the above table,

The highest frequency is 12which is for the blood groupO and the least frequency is 3which is for the blood group AB

Hence,

The most common blood group (highest frequency blood group) is O

The rarest blood group (least frequency blood group) is .AB
