Jun 9, 2021 · 1 Answer. The regression equation is there to tell you the direction of the correlation. If you know r2 = 0.64 r 2 = 0.64, then r = ±0.8 r = ± 0.8. To decide on whether the correlation is positive or negative you should look at the slope of the regression line. Since the slope is negative, r = −0.8 r = − 0.8.Oct 10, 2023 · The possible range of values for the correlation coefficient is -1.0 to 1.0. In other words, the values cannot exceed 1.0 or be less than -1.0. A correlation of -1.0 indicates a perfect negative ...

Saving money on graphing calculatorsSep 27, 2023 · The coefficient of determination is r2 = 0.6631 2 = 0.4397. Interpretation of r2 in the context of this example: Approximately 44% of the variation (0.4397 is approximately 0.44) in the final-exam grades can be explained by the variation in the grades on the third exam, using the best-fit regression line.Microsoft security. Accessibility center. The CORREL function returns the correlation coefficient of two cell ranges. Use the correlation coefficient to determine the relationship between two properties. For example, you can examine the relationship between a location's average temperature and the use of air conditioners.About the Lesson. This lesson involves investigating the connection between the scatterplot of bivariate data and the numerical value of the correlation coefficient. Consider a scatterplot of points that lie in a straight line and one whose points do not line in a straight line and interpret the correlation coefficient for each plot.
