Step 2 of 3:

Calculate the value of the sample standard deviation. Round your answer to one decimal place.

Consider the following data:

15, 15, 0, 15, 15, 0

Copy Data

Step 3 of 3:

Calculate the value of the range.

Solution

Consider the following data:

15, 15, 0, 15, 15, 0

no of data, n = 6

Mean of the data, u = { 15 - 15 + 0 + 15 - 15 + 0 } = 0

Sample variance, s² = [ (15-0)² + (-15-0)² +(0-0)² + (15-0)² + (-15-0)² + (0-0)² ]/(6-1) = 180

Sample standarad deviation, s = (180)^1/2 = 13.416

Value of the Range = 15 - (15) = 30
