Using a 'generic Set Up' in an Excel Spreadsheet:
x x -3.89 (x-3.89)^2
0 -3.89 15.1321
0 -3.89 15.1321
2 -1.89 3.5721
3 -0.89 0.7921
4 0.11 0.0121
5 1.11 1.2321
6 2.11 35.8726
7 3.11 56.6131
8 4.11 98.0941
35 sum/8 28.31 (2 decimal places)
35/9 3.89 SD 5.32 (2 decimal places)
A) Find median = 4 (middle)
B) Find mean= 3.89
C) Find the sample variance = 28.31
D) sd = 5.32
Wish You the Best in your Studies.
