why is the standard deviation used more frequently than the variance? choose the correct answer below. a. the units of variance are squared. its units are meaningless. b. the standard deviation is easier to compute. c. the standard deviation requires less entries from the data set.
Answer
Brief Explanations:
The variance is the average of the squared deviations from the mean, so its units are the square of the original data - set units. Standard deviation is the square - root of variance, having the same units as the original data, making it more interpretable.
Answer:
A. The units of variance are squared.
