(adsbygoogle = window.adsbygoogle || []).push({}); For the following data set of eight values, give the MEAN, DEVIATION (DEV), and AVERAGE DEVIATION (AD). Show a sample calculation for each: 0.77, 0.92, 1.12, 1.00, 0.96, 0.88, 1.16, 1.02

2. Relevant equations

Well before we began, can anyone take the courtesy and see if I'm getting the correct answer?

MEAN: 0.97875

DEV: .0126 (maybe?)

AD: ???

3. The attempt at a solution

DEV:

(-167/800)^2+(-47/800)^2+(113/800)^2+(-3/160)^2+(-79/808)^2+(29/160)^2+(33/800)^2 = 0.111635/(8-1) = 0.0159 =sqrt(0.0159)=0.126

I'm confused now....I think I found the standard deviation. However, I'm unsure how to even calculate the average deviation cause I don't have enough values. what am i doing wrong? What should I do next?
