The standard deviation provides insight into the distribution of values around the mean. If the standard deviation is small, the more narrow the range between the lowest and highest value. That is, values will cluster close to the mean. From your descriptive statistics, describe your standard deviations. What does this tell you about the variables?

Answer 1

The standard deviation for Salary tells us that there is a wide range between the lowest and highest value of Salary from the mean Salary.

The standard deviation for Hrly Rate tells us that there is a narrow range between the lowest and highest value of Hrly Rate from the mean Hrly Rate.

The standard deviation for Yrs of Svc tells us that there is a narrow range between the lowest and highest value of Yrs of Svc from the mean Yrs of Svc.

The standard deviation for Ed tells us that there is a narrow range between the lowest and highest value of Ed from the mean Ed.

The standard deviation for Age tells us that there is a narrow range between the lowest and highest value of Age from the mean Age.
