Big Ideas:
Data can be represented using tables, charts, and graphs, and scatter plots help reveal associations in quantitative bivariate data.
This lesson builds on students' work in 8th grade, where students created scatter plots and looked for associations between variables. In this lesson, students will compute the correlation coefficient, which represents the strength of a linear association between two variables.
Vocabulary:
bivariate, scatter plot, correlation, association, positive association, negative association, linear association, correlation coefficient
