Answers
Given : -5, -5,-5,-5,5
To Find : Standard deviation
Solution:
-5, -5,-5,-5,5
Mean = ( - 5 - 5 - 5 - 5 + 5 )/5 = - 3
xi mean xi - mean (xi - mean)²
-5 -3 -2 4
-5 -3 -2 4
-5 -3 -2 4
-5 -3 -2 4
5 -3 8 64
80
SD = √∑(xi - mean)² / n
= √80 / 5
= √16
= 4
The standard deviation of -5, -5,-5,-5,5 is 4
