You should get a message that says Done. Getting the correlation coefficient and regression equation: 1. Press the STAT button. 2. Highlight the CALC option ( ...
10.04.2020 · Step 3: Find the correlation coefficient. Next, we will calculate the correlation coefficient between the two variables. Press Stat and then scroll over to CALC. Then scroll down to 8: Linreg (a+bx) and press Enter. For Xlist and Ylist, make sure L1 and L2 are selected since these are the columns we used to input our data.
The correlation coefficient is very useful for understanding how strong the linear relationship is between two variables. The only problem is that it is quite messy and tedious to find by hand! And as I have mentioned many times before: statisticians do not find these things by hand.
How to find the correlation coefficient (r) using your graphing calculator 1. Create your scatterplot 2. Plot it on the coordinate plane and decide which regression model (see pg. 145 in your textbook) that best fits the data 3. Press: Stat; Calc and pick the regression model 4. “r” should be listed with the equation 5.
