The choice of appropriate method of data analysis depends on all of these factors. A parametric or nonparametric test may be preferred based on the normality and equal variance assumptions of the data. Whether the independent variable is between-subjects or within-subjects in nature affects the choice of statistical test (e.g., t-test or ANOVA). The number of levels of the independent variable affects the complexity of the analysis and the choice of the appropriate model. Therefore, all of these factors should be considered when selecting the appropriate method of data analysis.
