So in order to calculate the covariance from that, we use this correlation coefficient. Actually, it’s in there as R times the two sample standard deviations. So that’s what we’re doing here. RCL 1 is our 7, RCL 2 is our 11, and RCL 3 is our correlation coefficient. Our correlation coefficient calculator will also, whenever possible, display the interpretation of the result. It uses Evan's scale (1996) to describe the strength of correlation. This scale is based on the absolute value of correlation and the thresholds are the following: 0.8 ≤ |corr| ≤ 1.0 very strong; 0.6 ≤ |corr| < 0.8 strong;the acceptable alpha level of 0.05, meaning the correlation is statistically significant. Four things must be reported to describe a relationship: 1) The strength of the relationship given by the correlation coefficient. 2) The direction of the relationship, which can be positive or negative based on the sign of the correlation coefficient.TI-84: Least SquaresRegression Line (LSRL) Prev: TI-84: Correlation Coefficient Turn on “DiaGnosticOn” [2nd] “Catalog” above the ‘0’ to see the Correlation Coefficient.
