Question

Which is the population standard deviation of the data set: 8, 9, 10, 11, 12?

Answer 1

The population standard deviation of the data set is 1.414.

What is standard deviation?

Standard deviation is used to determine how the values in a group differs from the mean of the values in the group. It is a measure of variation.

How is standard deviation calculated?

1. Determine the mean of the observation
2. Determine the difference between each value and the mean and then square the result
3. Determine the mean of the sum of the squared differences and then find the square root of the mean:

Mean = (8 + 9 + 10 + 11 + 12) / 5 = 10

Sum of squared differences: (8 - 10)² + (9 - 10)² + (10 - 10)² + (11 - 10)² + (12 - 10)² = 10

√10/5 = 1.414
