Extrapolate You are extrapolating when the value you are finding is before the first point or after the last point. This means you may need to extend the line. When you extrapolate, you are making a prediction _____________ the data. It requires you to _______________the line. These predictions are less ______________. Making Predictions - Use your line of best fit to estimate the following: Question Answer Method of Prediction A student’s mark if they studied for 4 hours. A student’s mark if they did not study. How long a student studied for if they received 60 out of 100. How long a student studied for if they received 100 out of 100. Assignment 4.4 Lines of Best Fit 1. Identify the outlier, if any then draw a line of best fit. Check your lines of best fit with your elbow partner, do they look the same? 2. Consider the following two scatter plots a) Describe each relationship and their correlation. Which one has the stronger correlation?
