What is the standard deviation of the data set? 29, 36, 41, 53, 45, 30, 60
Digiron [165]
The standard deviation for the set of number will be found as follows:
mean=(<span> 29 + 36 + 41 + 53 + 45 + 30 + 60</span>)/5=294/7=42
next:
sum of (x-mean)^2=[(29-42)^2+(36-42)^2+(41-42)^2+(53-42)^2+(45-42)^2+(30-42)^2+(60-42)^2]
=804
thus the variance will be:
var=(804)/(7-1)=134
thus the standard deviation will be:
σ=√134=11.576
