Step 1
Standard deviation is a measure of the amount of variation or dispersion in a set of values. It tells us how spread out the values are from the mean. Now, let's analyze graph A and graph B. If graph A has a smaller standard deviation than graph B, it means that Show more…

Select all of the true statements about the standard deviation of a quantitative variable. -The standard deviation of a set of values is equal to 0 if and only if all of the values are the same. -The standard deviation of a group of values is a measure of how far the values are from the mean. -If a set of values has a mean of 0 and a standard deviation that is not 0, then removing a data point with a value of 0 will have no effect on the standard deviation. -Standard deviation is resistive to unusual values. -Standard deviation is always a nonnegative value. -Changing the units of a set of values (e.g., converting from inches to feet) does not affect its standard deviation.
