1. The problem statement, all variables and given/known data How does skew and range affect the standard deviation; does one affect it more than the other? 2. Relevant equations None 3. The attempt at a solution It seems as though if the range increases, the standard deviation increases because the SD is a measure of how spread apart from the mean each observation is. However, I have no idea how skew for a data set would affect the SD of that data set. Also, I am not really sure what the question is asking.
