Question

Calculate the Standard Deviation of the values:

9,4,11,0,8,7,3,6​

Answer 1

Answer:

In statistics, a population is a set of similar items or events which pertains to a question or experiment.

x1=9x2=4x3=11x4=0x5=8x6=7x7=3

Answer 2

Answer:

Math Formulas

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.
