## How To Find Correlation Coefficient Using Graphing Calculator Ti83

Summary: When you have a set of (x,y) data points and want to find the best equation to describe them, you are performing a regression. You will learn how to find the strength of the association between your two variables (correlation coefficient), and how to find the line of best fit (least squares regression …

- Of course, the next problem is to find the correlation coefficient for this regression. The good news is that the TI-83 would have been happy to find this if we had set it up properly. We need to turn on the Diagnostics. To do this the TI-83 has a special command. To find that command we need to look in the CAATALOG which we do by pressing

- This xy plot (or xz plot) has a correlation coefficient r, computed just like any other correlation coefficient. Compare the r for your data set to the critical value for the size of your data set. Ryan and Joiner determined that the critical value for sample size n , at the 0.05 significance level, , is 1.0063?.1288/v n ?.6118/ n +1.3505/ n ?.
