The outlier in the data set is 46 because it is the furthest away from the average sizes of the other data. Therefore, the mean will be 7.2, meaning the average of the data set is larger than it is meant to be. The median is 2.5 which wouldn't change much if 46 wasn't a part of the data. The mode is 2, which would only change if 1, or 3, was a replacement for 46.
