PLS-SEM is a variance-based modeling approach that has gained popularity in the fields of management and social sciences due to its capacity to handle small sample sizes, non-normal data distributions, and complex relationships among latent constructs. explain
Your sentence accurately summarizes the advantages of Partial Least Squares Structural Equation Modeling (PLS-SEM). Here's a clear, expanded explanation of each part of the statement:
✅ “PLS-SEM is a variance-based modeling approach…”
-
Variance-based means PLS-SEM aims to maximize the explained variance (R²) in the dependent (endogenous) variables.
-
Unlike Covariance-Based SEM (CB-SEM), which focuses on reproducing the entire covariance matrix and overall model fit, PLS-SEM emphasizes prediction and explaining target constructs.
✅ “…gained popularity in the fields of management and social sciences…”
-
PLS-SEM is widely used in:
-
Management research (e.g., leadership, organizational behavior)
-
Marketing (e.g., customer satisfaction, brand loyalty)
-
Information systems (e.g., tech adoption models like TAM/UTAUT)
-
Education and psychology
-
-
Its popularity stems from its flexibility and suitability for exploratory research and theory building, which is common in social science domains.
✅ “…due to its capacity to handle small sample sizes…”
-
CB-SEM often requires large samples (e.g., 200–500 cases) for stable and valid results.
-
In contrast, PLS-SEM works effectively with small to moderate samples (even <100, depending on model complexity).
-
This is especially helpful for studies involving hard-to-reach populations (e.g., faculty, executives, or niche consumers).
✅ “…non-normal data distributions…”
-
Many real-world datasets (especially survey-based) are non-normally distributed (e.g., skewed, kurtotic).
-
PLS-SEM does not require multivariate normality, unlike CB-SEM which relies on Maximum Likelihood Estimation (MLE).
-
Thus, it is robust to data violations and allows researchers to work with ordinal, skewed, or categorical survey data.
✅ “…and complex relationships among latent constructs.”
-
PLS-SEM supports multiple independent and dependent variables, mediating/moderating effects, and higher-order constructs.
-
It can model:
-
Reflective and formative indicators
-
Second-order constructs (e.g., multidimensional factors)
-
Interrelated paths in one model
-
-
This makes it ideal for complex models like in technology adoption, brand equity, or academic integrity frameworks.
🔁 Summary Table: PLS-SEM Strengths
Strength | Explanation |
---|---|
Works with small samples | Suitable for 100–200 cases or even less in some models |
No need for data normality | Handles skewed and ordinal data well |
Suitable for complex models | Can handle mediation, moderation, and multi-layered latent variables |
Focus on prediction (R², Q²) | Prioritizes explaining variance over fitting the whole covariance matrix |
Can use formative indicators | Allows constructs built from distinct components (not just reflections) |
