2-Way ANOVA: Power Calculation Results

Click the OK button in the 2-Way ANOVA: Power Calculation Parameters dialog box to display the 2-Way ANOVA: Power Calculation Results dialog box, which contains two tabs: Quick and Settings I/O.

Summary box

The Summary box at the top of the dialog box shows the current fixed, or baseline, parameters for the analysis. These can be altered at any time without losing any changes in the settings of the current dialog box by clicking the Change Parameters button.

Copy button Click the Copy button to copy either the selected text (if text has been selected) in the Summary box or all of the text (if no text has been selected) to the Clipboard. Note that the copied text retains formatting information (such as font, color, etc.).

Contract/Expand button Click the Contract/Expand button to contract or expand the Summary box. When contracted, you see only one line of the Summary box text and can scroll through the text using the scroll bar. Note that when contracted, the text is scrolled so that the first non-blank line is at the top. When expanded (the default setting), the entire Summary box is displayed.

Calculate Power

Click the Calculate Power button to calculate power for the currently selected fixed parameters. A spreadsheet containing the fixed parameters and the results of the power analysis will be displayed. The fixed parameters are discussed on the 2-Way ANOVA: Power Calculation Parameters dialog box. Key results are the critical value of F, the value used for the statistical test, and the actual power.

Change Parameters

Click the Change Parameters button to alter the fixed parameters from the 2-Way ANOVA: Power Calculation Parameters dialog box without losing any changes in the settings of the current dialog.  

Back

Click the Back button to return to the 2-Way ANOVA: Power Calculation Parameters dialog box without saving any of the current changes.
