Find the mean deviation of a set of numbers: 14, 15, 16, 17, 18, and 19.
2.5
1.7
1.5
3.5
Correct answer is C
x̄ = 14+15+16+17+18+196=996 = 16.5
M . D = (14−16.5)+(15−16.5)+(16−16.5)+(17−16.5)+(18−16.5)+(19−16.5)6
M.D = (−2.5)+(−1.5)+(−0.5)+(0.5)+(1.5)+(2.5)6
Taking the absolute value of the deviations
M.D = 2.5+1.5+0.5+0.5+1.5+2.56
M.D = 96 = 1.5
