The purpose of this study is to introduce a newly developed and empirically validated user-friendly tool to assist researchers in choosing and justifying single-case design quantification techniques. Different quantification techniques, research questions, data or graph characteristics, and desired features that may affect the appropriateness of a single-case experimental design quantification technique are identified to be included in the tool. The resulting tool provides a ranking of recommended quantification techniques, from most to least appropriate, depending on the user input. A pretest and posttest design was utilized to test the effectiveness of the tool. Results show that those who use single-case designs may need support in choosing and justifying their use of quantification techniques, and that the developed tool can assist in this process.
