Question

calculate the standard deviation for the following:
5,8,7,11,14
Answer as soon as possible and answer correctly​

Answer 1

Answer:

Mean = sum of values / N (number of values in set)

Variance = ((n1- Mean)2 + ... nn- Mean)2) / N-1 (number of values in set - 1)

Standard Deviation σ = √Variance

Population Standard Deviation = use N in the Variance denominator if you have the full data set. The reason 1 is subtracted from standard variance measures in the earlier formula is to widen the range to "correct" for the fact you are using only an incomplete sample of a broader data set.
