Ribbon bar. Select the Statistics tab. In the Tools group, click Calculators and on the menu, select Correlations to display the Pearson Product Moment Correlation Distribution dialog box.

Classic menus. On the Statistics - Probability Calculator submenu, select Correlations to display the Pearson Product Moment Correlation Distribution dialog box.

Use the options in this dialog box to compute the p-value for a given correlation coefficient, or you can enter a desired p-value and determine the correlation coefficient (based on a specified sample size).

The parameters used in this dialog box are N (the sample size), r (the correlation coefficient), p (the significance value), and Fisher z (the critical value of the distribution). These parameters can be specified or computed. To use this dialog box, enter values in two of the edit fields (leaving the other two blank), and then click the Compute button to compute the remaining two values.

Using either one- or two-tailed tests, you can compute the p-value and Fisher z from a given r and sample size (N), compute r and its Fisher z value from a given p and sample size (N), or compute r and the p-value based on a specific Fisher z value and sample size (N).

After performing the selected calculations, you can send the results of the computation to a report. These values will be sent to a report when you click the Compute button, not when you change the parameters with the microscrolls. Therefore, you can edit the parameters using the microscrolls and review the results in the boxes in this dialog box; then, when you are ready, click the Compute button to send the resulting values to a report.
