What would the mean values be? (the green boxes)
Answer:
First Mean = 5
Second Mean = 3
Third Mean = 6
Fourth Mean = 9
Explanation:
For each column you just add up the data numbers and divide them by how many numbers is in that column which would be 3.
0.5 + 14.0 + 0.5 = 15 | 15 / 3 = 5
2.5 + 4.0 + 2.5 = 9 | 9 / 3 = 3
6.0 + 7.0 + 5.0 = 18 | 18 / 3 = 6
8.0 + 10.0 + 9.0 = 27 | 27 / 3 = 9
