To show the class how to find the mode and median, Mr. Moreno asked five book club members to stack up Student Guides on his desk equal to the number of books they had read last week. Edward, Shannon, Roberto, Alexis, and Ana arranged their stacks from smallest to largest. The number of books stacked up most often is the mode. The median number of books is the number in the stack exactly in the middle.
Looking at Mr. Moreno's Data
- Use the picture of the stacked books to answer these questions.
- What are the numbers in this data set?
- Whose stack has the median number of books?
- What is the median number of books?
- What number of books is the mode; that is, what number of books appears most often?
- Which number, the median or the mode, is more “typical” for this group of data? Why?
