Median and the Middle Child

My complete unit on Introduction to Statistics is now online. Examples include problems with whole numbers, decimals and integers. This unit includes lessons on the following topics:

1. range
   
2. arithmetic mean
   
3. non-routine mean problems
   
4. median
   
5. mode
   
6. practice exercises
   
7. challenge exercises

When I think of the median, I always think about how I was the middle child in a family of five children, as illustrated by my animated middle child! Of course, an even number of data is also covered in the median lesson. But for me, an odd number of data is just so much more fun!
