Reflection: Discourse and Questioning Box Plots and Interquartile Range - Section 6: Closure and Ticket to Go

 

During the closure, I also asked, “How many weeks are included in Sarah’s data set?”  I called on students to share their observations.  I wanted to make sure that students understood that just by looking at a box plot they cannot tell the number of values in the data set.  This can be confusing to students when they are just learning about box plots, since you can determine the values in a data set from most other types of graphs.

Objective: SWBAT: • Identify and label the minimum, maximum, lower quartile, upper quartile, and median of a data set and box plot. • Define and identify interquartile range. • Analyze and compare box plots.

Big Idea: What is interquartile range? What does the IQR tell us about a data set? Students work on creating and comparing box plots.
