The diagram is a treemap containing colored and sized rectangles, each representing a research method category. On the left, blue boxes dominate for “Quantitative methods,” subdivided into “Descriptive Statistics,” “Confirmatory Factor Analysis (C F A),” “Principal Component Analysis (P C A),” “Structural equation modelling (S E M),” “Technique for Order Preference by Similarity to Ideal Solution (T O P S I S),” “Weighted sum (W S),” “Entropy,” “Ordinary Least Squares,” “Generalised methods of moments (G M M),” and “Exploratory Factor Analysis (E F A).” At the top right, gray boxes represent “Mixed-Methods,” “Fuzzy Logic (F L),” “Multi-Criteria Decision Making (M C D M),” “Analytical Hierarchy Process (A H P),” and “Meta-Analysis.” At the bottom right, orange boxes are for “Qualitative methods,” containing “Grounded Theory,” “Case Study,” “Textual Analysis,” “Discourse Analysis,” and “Meta-Frontier Analysis”. A legend on the top includes a blue square representing Quantitative methods, a red square representing Qualitative methods, and a gray square representing mixed methods.Summary of research methodologies.
