How would you determine the correct statistical test to use in a research study?

To determine the correct statistical test for a research study, first identify the type of data you have (e.g., nominal, ordinal, interval, or ratio) and the research question you aim to address. Next, consider the number of groups being compared (e.g., one-sample, two-sample, or multiple groups) and whether the data meets assumptions like normality and homogeneity of variance. Finally, match your study design (e.g., independent vs. paired samples) with appropriate tests, such as t-tests for comparisons of means or chi-square tests for categorical data.
