Explain the difference between exact and approximate linear models. Difference between extrapolation and interpolation. Give examples of each. What is correlation coefficient? How do we find this value with a calculator? When your data doesn't lie on a straight line, explain what the line of best-fit is and how you would find the equation for it using your calculator.

Step 1
Exact and Approximate Linear Models: An exact linear model is a mathematical equation that perfectly fits a set of data points. It means that the model can predict the exact value of the dependent variable for any given value of the independent variable. On the Show more…
