3.1 A histogram of a set of data indicates that the distribution of the data is skewed right. Which measure of central tendency will likely be larger, the mean or the median? Why? Choose the correct answer below. A. The mean will likely be larger because the extreme values in the left tail tend to pull the mean in the opposite direction of the tail. B. The median will likely be larger because the extreme values in the right tail tend to pull the median in the direction of the tail. C. ...
