#### Question Details

Mean ,0,0,0,0,0,15,15,30,30,45, and 60/12

So 195/12=

Mean =16.25

To calculate deviance for each data value from the mean you must subtract each of the individual numbers by the mean as follows:

Deviation of Mean: 0-16.25= -16.25, 0-16.25= -16.25, 0-16.25=- 16.25, 0-16.25= -16.25, 0-16.25= .25, 0-16.25= -16.25, 15-16-25=-1.25, 15-16.25=-1.25, 30-16..75, 30- 16..75, 45-16..75, 60-16..75

-------------?

The deviances are squared and then added together:

(-16.25)2 + (-16.25)2 + (-16.25)2 + (-16.25)2(-16.25)2 + (-16.25)2+(-1.25)2+(1.25)2+(13.75)+(13.75)+(28.75)+(43.75)=
