Lesson 7

Confident Models

These materials, when encountered before Algebra 1, Unit 3, Lesson 7 support success in that lesson.

Lesson Narrative

The mathematical purpose of this lesson is for students to understand that correlation coefficients describe the relationship between variables and the trend they create on a graph. Previously, students learned about lines of best fit and they distinguished between information given by a linear model and actual data. In the associated Algebra 1 lesson, students find and interpret correlation coefficients. Students make use of structure (MP7) when they think about how scatter plots look when a linear model is a very close fit to the data and when it is not. They reason abstractly and quantitatively (MP2) when they synthesize parts of a linear model and think about how to rank the models based on how likely the data is to lay directly on the line produced from the linear model.
