What measure of central tendency (mean, median or mode) would be best for the following set of data?
0, 89, 92, 97, 99, 100

• Mode, because it is the one that shows up the most.
• Median, because there is an outlier.  The outlier could be incorrect and would influence the mean too much.
• Mean, because there is not an outlier.  You should always use the mean.
• There is not a best measure of central tendency for this data.
