Question
What is the relationship between the variance and the standard deviation?Select one:A. Variance is the square of the standard deviationB. Variance is the square root of the standard deviationC. Variance is twice the standard deviationD. No constant relationship between variance and standard deviation
Solution
The correct answer is A. Variance is the square of the standard deviation.
Here's why:
-
Variance is a statistical measurement that describes the spread of data points in a data set around the mean. It measures how far each number in the set is from the mean and thus from every other number in the set.
-
Standard deviation, on the other hand, is a measure of the amount of variation
