Think about the situation where you are investigating the relationship of study time vs. exam grade. a. Which variable would be on the x-axis (and why)? b. Which variable would be on the y-axis (and why)? c. Would you expect the slope to be positive or negative (and Why)? 2) Contrast and compare interpolation with extrapolation. Which is “safer” to use and why? 3) Look up how “the best fit straight line” is constructed. The term “Least squares” should be in your explanation. 4) If I plot some data and end up with a r2 of (-) 0.99, is my plot useless? Explain.
