If the variance of a population is 16, what is the standard deviation? (2023)

If the variance of a population is 16, what is the standard deviation? (2023)

Step 1: Understand that variance is a measure of how much the values in a population differ from the mean.
Step 2: Know that the standard deviation (SD) is a measure of the average distance of each value from the mean.
Step 3: Remember the relationship between variance and standard deviation: SD is the square root of variance.
Step 4: Since the variance given is 16, calculate the square root of 16.
Step 5: Find the square root of 16, which is 4.
Step 6: Conclude that the standard deviation is 4.
