Given the following set of data:
8.7 4.6 3.6 6.4
2.4 3.1 1.8 6.9
2.0 4.5 1.6 6.0
We will find the mean of the data as follows:
Where n is the number of the data = 12
the sum of the data =8.7+4.6+3.6+6.4+2.4+3.1+1.8+6.9+2.0+4.5+1.6+6.0 =51.6
So, the mean = 51.6/12 = 4.3
So, the answer will be Mean = 4.3
