Answer

Answer:

Blood Type Frequency
A 7
B 8
AB 4
O 6
This is nominal data.

Explanation:

Step1: Count A - types

Count all 'A's in the data set. There are 7.

Step2: Count B - types

Count all 'B's in the data set. There are 8.

Step3: Count AB - types

Count all 'AB's in the data set. There are 4.

Step4: Count O - types

Count all 'O's in the data set. There are 6.

Step5: Determine data type

Blood types have no natural order, so it's nominal data.
