(8) The student models data, makes predictions, and judges the validity of a prediction. The student is expected to:

• (A) determine if there is a linear relationship in a set of bivariate data by finding the correlation coefficient for the data, and interpret the coefficient as a measure of the strength and direction of the linear relationship;

• (B) collect numerical bivariate data; use the data to create a scatterplot; and select a function such as linear, exponential, logistic, or trigonometric to model the data; and

• (C) justify the selection of a function to model data, and use the model to make predictions.
