Since the table for the data using excel as
Xi | Yi | Xi*Yi | |
4 | 2 | 8 | |
-1 | 6 | -6 | |
8 | 0 | 0 | |
2 | 5 | 10 | |
1 | 2 | 2 | |
4 | -1 | -4 | |
3 | -18 | -54 | |
Sum= | 21 | -4 | -44 |
Mean(M)= | 3 | -0.57143 |
So,
6. SX= Sum of X=21
7. Sy= Sum of Y =-4
8. SXY= Sum of the product of X and Y =-44
9.m is the slope of the data is calculated as by the table shown below as
m= SP/SSX = -32/48 = -0.66667
