The outlier of the data set is 92. Lets first find everything with the outlier. Mean: 60.08 Median: 57 Mode: 52 Range:46
Now let's take out the outlier of the set and see the difference. Mean: 54.27 Median:56 Mode: 52 Range: 15
So as we can see without the outlier everything is closer together. The outlier shouldn't be included because that makes the entire set screwed up. The data is more accurate without the outlier.
