The mathematical purpose of this lesson is for students to understand that there are different types of relationships between variables. Students learned about positive and negative correlations in grade 8. They also learned about associations when working with two-way tables. Therefore, students are familiar with the idea of variables having a relationship. This lesson prepares students to interpret correlation coefficients in the supported Algebra 1 lesson. Students must reason abstractly and quantitatively (MP2) when they interpret the relationship between variables in a mathematical sense.
