The type of this data is categorical data, specifically nominal data since the blood types are categorical and do not have any numerical significance.
The most common blood type in the sample is A.
The least common blood type in the sample is AB.
To determine the percentage of the population that has type O blood, we can add up the frequency of all individuals with type O blood (which is 7 in this sample) and divide by the total sample size (30) and multiply by 100. This gives us a percentage of 23.3%.
Frequency distribution:
Blood Type Frequency
A 9
B 4
AB 2
O 7
Relative frequency distribution:
Blood Type Frequency Relative Frequency
A 9 0.3
B 4 0.133
AB 2 0.067
O 7 0.233
