For the data set: 0.09, 0.10, 0.11, 0.13, 0.09, 0.11, 0.10, 0.07 to obtain information of the precision of the data set the standard deviation would be:

a. 0.018
b. 0.022
c. 0.0166
d. 0.01

Option A is correct (0.018)

S.D≅0.018

Explanation:

Option A is correct (0.018)

General Formula for Standard Deviation is:

Where:

is the data value

is the mean/average of data

n is the total number of data elements

Calculating

Calculating n-1:

Total number of terms=8

n-1=8-1=7

Standard Deviation is:

S.D≅0.018
