Scatter plots and association
Plot bivariate data on a scatter plot and describe the direction, form and strength of any association between the variables.
Line of best fit
Draw a line of best fit on a scatter plot, use it to make predictions by interpolation, and evaluate whether a given line is a good fit for the data.
Predictions and limitations
Use lines of best fit to interpolate and extrapolate, and identify limitations of statistical models.
