Respuesta :
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?
- Determine the mean of the observation
- Determine the difference between each value and the mean and then square the result
- 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
