Suppose that shoes become very difficult to obtain and this shoe store can only order one size shoe for the next 12 months. The shoe store wants to maximize the number of shoes they will sell, especially given the fact that they will only be able to carry one size shoe for the next 12 months. Which measure of central tendency would be the most likely to be a good indication of the one shoe size they should order in order to maximize the number of shoes they will sell?
