To find: the distributions which show a larger standard deviation
Answer to Problem 102E
The graph of variable A will have a higher standard deviation.
Explanation of Solution
Given:
The more values that deviate from the mean, the higher the standard deviation will be.
The mean lies roughly at the (horizontal) middle of the histogram.
The graph of variable A will then have a higher standard deviation, because we note that the bars to the left/right in its histogram are higher compared to the histogram of variable B, which indicates that more values deviate from the mean for variable A.
