Crucial factors should be considered during the selection of the study design, which is the formulated research question, as well as the method of participant selection. This study design looks for cause and effect (if A, then B), so it requires having control over at least one of the independent, or treatment variables. Qualitative research is the process of collecting, analyzing, and interpreting non-numerical data, such as language. Quantitative designs typically fall into four categories: experimental, quasi-experimental, descriptive, or correlational.
