About the Lesson

Watch the activity tutorial

Students use golf driving distances from PGA and LPGA records to explore correlation between year and distance. The relationship shows a relatively strong positive correlation over a period of almost 20 years. Students then use the relationship to predict driving distances into the future and compare the accuracy of these predictions against more recent data.
