What is the typical role of statistical analysis in single-subject research?

A researcher is finalizing the data analysis for a single-subject study on a new therapy. Arrange the steps of the analysis process in the correct order according to the standard practice in which statistical analysis is used as a supplement.

A researcher decides to use statistical analysis as the primary method for identifying a treatment effect in a single-subject study, arguing that it is more objective than visual inspection. This researcher’s approach correctly reflects the role of statistical analysis in single-subject research.

A researcher proposes that statistical analysis should replace visual inspection as the primary method of data analysis in single-subject research because it allows for more efficient comparisons across studies. According to standard methodology, this proposal is flawed because statistical methods are intended to serve as a(n) _____ tool that supports rather than replaces visual inspection.

In single-subject research, both visual and statistical approaches are used to analyze data, but each serves a distinct role. Match each analytical method or function with the role it typically plays in the research process.
