How does an outlier affect the mean, median, mode, or range? Does it always have an effect? What predictions can you make about how the outlier will affect these measures?
These 6 quick and easy tables will help you students make generalizations (such as a larger outlier will always increase the mean).
It will also help them realize that they still have to do the math, and they can't just glance at an outlier and guess how the measures will be affected (the median is sometimes affected, and sometimes not).
Have your students work with a partner, try it for homework, or split the 6 tables up among small groups, and then compare. There are 4 Reflection Questions at the end, so you can check students' understanding.
