Lesson objective: Understand that a statistical question anticipates variability in the data related to the question and accounts for it in the answers.

Students bring prior knowledge of data displays from 4.MD.B.4. This prior knowledge is extended to understanding statistical questions as students determine which questions presented can be represented using a data display. A conceptual challenge students may encounter is identifying when a question anticipates a variety of answers.

The concept is developed through work with dot plots, which students will connect to statistical questions by identifying when their results can be plotted on a dot plot.

This work helps students deepen their understanding of number because statistical questions can be used to generate numeric data sets that can be plotted on line plots.

Students engage in Mathematical Practice 3 (Construct viable arguments and critique the reasoning of others) as they determine which Chef should be fired using the fact that Big Bob Boss requested a visual presentation. Students need to support their argument that Chef Kevin should be fired because Chef Laura’s list will allow for more statistical displays.
