Statistics Outlier

If there is an outlier in your data (a point very far from the other data, or a very long whisker), what is the best measure of center to use and why?

• Median is best because the outlier skews the data.

• Mean is best because the outlier doesn't skew the data.

• Mode is always the best measure of center because it shows the most.

• Mean will decrease.

• Mean will increase.

• Mean will stay the same.
