Interpret linear models
Build on students' work with linear relationships in eighth grade and introduce the correlation coefficient. The focus here is on the computation and interpretation of the correlation coefficient as a measure of how well the data fit the relationship. The important distinction between a statistical relationship and a cause-and-effect relationship arises in S.ID.9
S.ID.9
Distinguish between correlation and causation.

• Interpreting Categorical and Quantitative Data Curriculum Guide
The Utah State Office of Education (USOE) and educators around the state of Utah developed these guides for the Secondary Mathematics 1 Cluster "Summarize, represent, and interpret data on a single count or measurement variable" / Standards S.ID.1, S.ID.2 and S.ID.3 and Cluster "Summarize, represent, and interpret data on two categorical and quantitative variables" / Standards S.ID.5 and S.ID.6 and Cluster "Interpret linear models" / Standards S.ID.7, S.ID.8 and S.ID.9.
• Linear Regression and Correlation
In this lesson students will plot data onto a scatter plot and then determine the line of best fit for the data sets.
