Hi there,
Wages......(x-mean).......(x - mean)^2
19.................0................0
24.................5................25
16................-3................9
29................10................100
7................-12................144
Total............Total.............Total
95/5..............0................278
Mean = 19
Standard Deviation = √(Total(x - mean)^2)/n -1
Standard Deviation = √(278)/4
Standard Deviation = 69.5
Hope this helps :-)
