# Lesson 15

Where Are We Eating?

These materials, when encountered before Algebra 1, Unit 1, Lesson 15 support success in that lesson.

### Lesson Narrative

The mathematical purpose of this lesson is for students to interpret distributions and match them to situations. Previously, students compared data sets by calculating measures of center and measures of variability. In the associated Algebra lesson, students compare and contrast situations using measures of center and measures of variability. In this lesson, students use data distribution shapes to inform their decisions about which data set represents the best scenario. By understanding how the shape of a distribution is connected to a situation, students are more fully prepared to compare similar situations. Students reason abstractly and quantitatively (MP2) when they connect distribution shapes to situations. Student construct a viable argument (MP3) when they explain their reasoning for selecting the best situation, given data.

### Learning Goals

Teacher Facing

- Use data distribution shapes to compare data sets.

### Student Facing

- Let’s use graphical representations to compare real-world scenarios.
