How do box plots help compare data? Think about this question as you compare the data below that shows the ages of students at three schools. Homework Help ✎

Which school is a K-8 school? How do you know? Does that school have more students in grades K-2, 3-5, or 6-8? Why?

What does the box plot for School C tell you about 11-year-old students at that school?

How many students attend School C?

Make a conjecture about how the data for these plots was collected.

What statements can you make about the students at School B based on its box plot? Consider the center, shape, spread, and outliers.

Look at the plots. Which school's plot has the largest range? What does this tell you about the students that attend that school?

Think about how these types of plots are drawn.

Which portion of the plot would tell you about 11-year old students?

11-year olds are 50% of School C's population.

Can you determine from these kinds of plots the total number of students?

The number of students cannot be determined from this plot.

Think about how one would get this kind of information from each of these schools.
