﻿ Find Correlation Coefficient On your TI-84 Calculator (in 10 Seconds) - 2021
How to find the Correlation Coefficient on TI-84 Calculators in 3 easy steps
Using your TI-84 Calculator, compute the Correlation Coefficient as described below.

1) Press 2ND 0 (which opens your Catalog), next scroll down and click DIAGNOSTIC ON as shown below in

2) Now enter the x-y List under STAT -> Edit .
Enter at least 2 pairs of x-y data to find the Correlation Coefficient on Calculator

3) Next, press STAT -> Calc -> LinReg(ax+b), select CALCULATE and Press ENTER to find the Correlation Coefficient r on the TI-84 Calculator

Voila, the Correlation Coefficient is displayed behind the letter r. r^2 is called the Coefficient of Determination.

Remember that a Correlation Coefficient r=1 means that your Regression Line passes through the given x-y data with a positive slope.
Conversely, r=-1 means that your Regression Line passes through the given x-y data with a negative slope.
Finally, r=0 means that there is no correlation between the given x-y data, just wildly scattered without pattern.
