This "secret message" activity will amuse your students and teach them about the effects of outliers on the median and mean.
Directions: In each row, there is one data set with an outlier, and the same data set without the outlier. Determine which set of data has the greatest mean or median, as specified. Circle the letter next to the data set that has the greatest mean or median, as specified. The first one has been completed for you.
At the end, read the message from top to bottom. It reads, "not like the rest." (The other letters spell "just plain weird").
And all you have to do is copy it! The prep is all done for you. It's easy to check. Just see if they found the secret message! It's up to you to determine how much work you require your students to show. Use it as group work, homework, enrichment, or extra practice.
