Answer:
Data Set A = 6.5
Data Set B = 4
Step-by-step explanation:
The mean is just the average. It's calculated by adding up the scores and dividing the total by the number of scores in the group altogether.
For Data set A, you add 4 + 4 + 5 + 6 + 7 + 8 + 9 + 9 = 52
Then divide the total by how many numbers are in the set.
In this case, 52 ÷ 8 = 6.5
For Data set B, do the same. 3 + 3 + 3 + 4 + 4 + 5 + 5 + 5 = 32 32 ÷ 8 = 4
