The standard deviation alone does not measure relative variation. For example, a standard deviation of $1 would be considered large if it is describing the variability from store to store in the price of an ice cube tray. On the other hand, a standard deviation of $1 would be considered small if it is describing store-to-store variability in the price of a particular brand of freezer. A quantity designed to give a relative measure of variability is the coefficient of...

The standard deviation is a measure of spread. For datasets with a high standard deviation, the mean is usually less reliable as a measure of central tendency. We know that outliers effect the mean. We express that by saying: the mean is sensitive to outliers. Would you say that the standard deviation is also sensitive to outliers? How might you justify your answer?
