Given the following set of data: 1,1,2,2,2,3,5 Will an outlier such as 30 have a greater effect on the median or the mean? Justify your answer.
What is the mean? The median is the middle number in a set of data after it has been ordered from least to greatest. The effect will be minimal. The mean has to do with the "evening out" of the numbers in a set of data. An outlier has a greater effect on the mean. In the above set of data, the median is 2 with or without the outlier. The mean is 2.3 without the outlier, and it is 5.75 with the outlier.
