Represent bivariate data on a scatter plot, and describe how the variables’ values are related.
It’s important to keep in mind that the data must be linked to the same “subjects,” not just two unrelated quantitative variables; being careful not to assume a relationship between the actual variables (correlation/causation issue).
a. Fit a function to real-world data; use functions fitted to data to solve problems in the context of the data.  Emphasis is on linear models and includes the regression capabilities of the calculator.

Do not assume that an association between two variables implies that one causes another to change.
