Correlation
Coefficient Learn how to interpret the correlation coefficient. To determine ways to identify when a set of data fits a linear
trend. Graphing
Linear Relationships Recognize how relationships between variables can be represented
on a graph. To use what we know about linear trends to create equations. To determine the difference between direct and partial variation.
