We illustrate use of the decision-aiding process with three example scenarios and lay out implications for researchers.Ī major aim of empirical research methodology is to design studies that are likely to reject the null hypothesis if it is indeed false. These criteria and heuristics are translated into questions that researchers should go through during the decision process. This process consists of five user-centered considerations – two functional criteria (software input software output) and three usability heuristics (learnability ease of use accessibility) – which are organized into a workflow. Centering on users’ wants and needs, we propose a decision-aiding process to assist researchers in identifying appropriate power analysis tools. We review the emergence and current state of power analysis software tools, and use the concept of User-Centered Design as an analytical lens for examining the relationship between researchers’ needs and power analysis tools’ characteristics. Given the complexity of conducting such analyses, software tools are essential.

The license file is available for download via the following link, and you will be asked to provide a valid Kent login to access this.Instructions follow for versions 16 and 17, though you should note that the earlier version is no longer supported by the makers of the software. If you need to update a current installation you can either download the newest version from the link shown, or link a new license file when the current one expires at the end of August.
