With two-variable statistical data accumulated in the statistics registers, what is an entity relationship (er) diagram can estimate a new y-value. Key in a new x-value. Press gR. Key in a new y-value. Press gQ. Example: Using the accumulated statistics from the preceding problem, estimate the amount of sales how to find the linear correlation coefficient on a calculator by a new salesperson working 48 hours per week.

Estimated sales for a 48 hour workweek. The reliability of a linear estimate depends upon how closely the data pairs would, if plotted on a graph, lie in a straight line. The usual measure of this reliability is the correlation coefficient, r. This quantity is automatically calculated whenever. A correlation coefficient close to 1. On the other hand, a correlation coefficient close to 0 indicates that the data pairs do not lie closely to a straight line; and a linear estimate using this data would not be very reliable.

Example: Check the reliability of the linear estimate in the preceding example by displaying the correlation coefficient. The correlation coefficient is close to 1, so the sales calculated in the preceding example is a good estimate. Press 0gR to compute the y- intercept A.
