This program, companion software to the text "Statistical Power Analysis, Second Edition, " includes the following features: * Spreadsheet Input. Data may be entered by means of a spreadsheet interface. As any cells in the spreadsheet (Mean, SD, N, Alpha, Tails, etc.) are modified by the user, the value of Effect Size and Power are simultaneously updated. * Graphic Input. Alternatively, data may be entered by means of a graphic interface. Cursor keys are used to modify graphs of the group distributions, and the value of power is updated in response. * Active HELP Screens. In addition to providing instructions and explanations, the HELP screens function as worksheets which enable the user to compute various parameters and return these values to the program. * Simulations. The program can run on-screen Monte Carlo simulations, repeatedly drawing samples from a user-defined population and testing each sample for significance. Useful for teaching! * Tables and Graphs. The program creates both tables and graphs of power as a function of N, Effect Size (Mean Difference, Correlation, etc.) and Alpha. Interface with graphics programs generates presentation quality graphics. * Procedures. The program produces power analyses for designs using t-Tests, Correlations, Proportions (Chi- square with or without Yates correction), Oneway and Factorial ANOVA/ANCOVA, and Multiple/Hierarchical regression. The program runs on any IBM or compatible computer; all functions work properly on monochrome as well as on color monitors. A 185-page manual is also available with the software. Please specify disk size (5.25 or 3.5) when ordering.
