If successful, you should find the result to be <1 4 7>. Run the program and input the correct 6 values.
In our example, a correlation coefficient of 0.9145 indicates a strong positive relationship between the two variables. Try finding the cross product of <5 -3 1> and <-1 2 -1>. The following table shows the rule of thumb for interpreting the strength of the relationship between two variables based on the value of r: Absolute value of r

How to Interpret a Correlation Coefficient On the new screen we can see that the correlation coefficient (r) between the two variables is 0.9145. Scroll down to Calculate and press Enter. Press Stat and then scroll over to CALC. Then scroll down to 8: Linreg(a+bx) and press Enter.įor Xlist and Ylist, make sure L1 and L2 are selected since these are the columns we used to input our data. Next, we will calculate the correlation coefficient between the two variables. Step 3: Find the correlation coefficient. Enter the values for the first variable in column L1 and the values for the second variable in column L2: Next, we need to enter the data values for our two variables. The diagnostics are now turned on so that we can calculate the correlation coefficient between two variables.
Scroll down to DiagnosticOn and press ENTER. To do so, press 2nd and then press the number 0.
