Solution
Answer: Option B
Solution:
The standard deviation (S. D.) is a measure of the amount of variation or dispersion of a set of values. A low S. D. indicates that the values tend to be close to the mean while a high S. D. means that the values are spread out over a wider range. Hence, if all values are negative then S. D. will be positive.
