What fits best? Pupils watch a video that reviews creating a scatter plot. Learners develop an understanding of correlation and determine whether it is moderate, strong, or none as well as positive or negative. Finally, they use a graphing calculator to find the equation of a curve of best fit to solve problems and use the problems in the worksheet to practice the new skills.
