What exactly is a Correlation Coefficient?
How to find the correlation Coefficient using the TI Nspire: Video
---------------------------------
Sometimes the best model for data isn't a straight line. Sometimes it is a curve.
Here are some examples of different types of curves or functions: Examples

EOC Practice Problem
(It is a negative correlation. So it has to be A or B. Since the plot points are spread out quite a bit from the regression line of best fit, it could hardly be the near-perfect -0.99 answer. Therefore it would most likely be closer to -0.65. We enter the tabular data in the calculators and verify that "r" is indeed -0.65.
Problems two was also on the board. we did not complete it before being called to the gym for PI Day.
Problem.
Graph of linear and quadratic regression
The quadratic curve fits the data much better than the linear regression. How much better? The correlation coefficient for the linear regression was in the positive 0.40's The correlation coefficient for the quadratic regression was in the positive 0.90's
