Structural Equation Modeling (SEM)

1. What is a model, and how can one be built?2. How is factor analysis incorporated into the model?3. How are the results of a full meauserement and structural

model?4. How can what has been learned be used to interpret actual

research results ?5. How is SEM used in causel inference?

Objective of this presentationWe will be able to develop a research model and test our hypotheses through Structural Equation Modeling.

Structural Equation Modeling

What is Structural Equation Modeling (SEM) ?

SEM is a regression analysis for measuring the relations among variables

SEM provides analysis of

Confirmatory Factor Analysis

Structural Model


1. What is a model, and how can one be built?

A model is a representation of a theory.

Theory is a systematic set of relationships.


2. How is factor analysis incorporated into the model?


3. How are the results of a full meauserement and structural model?


4. How can what has been learned be used to interpret actual research results ?


5. How is SEM used in causel inference?


LET’S DO TOGETHER TO SEE A REAL EXAMPLE... Generally, master thesis consists of 5 chapters

Chapter I: Introduction

Chapter II: Literature Review

Chapter III: Research Methodology

Chapter IV: Result

Chapter V: Discussion and Conclusions


1. Choosing a study topic... Explorotary or ? We can find the topic in Journal papers (generally, inside of future study directions or e.g., conclusions, or limitations) Asia University, Library website for example: www.proquest.com or www.googlescholar.com

2. We need to determine objective...

3. We need to develope hypotheses... (e.g., literature review)

4. Methodology... (quantitative, qualitatitve) if quantitative which method e.g. SEM?

5. Interpration of the result for conclsions and implications...


For example,

1.We chosed a topic which we really like. We are doing a study on tourism destination brand equity.

2.Our objective is to provide a new tourism destination brand equity conceptual model in marketing literature.

3.We have already reviewed the literature and developed our hypotheses.

4.We have 5 constructs (e.g., variables or called latent variables in SEM).

5.We have found that SEM is the best way and provide us powerful analysis technique. Because SEM provides us to see the relationship of all 5 constructs.


We will be conducting confirmatory factor analysis (CFA) and structural model...

CFA is to see measurement variables are systematic and logical ?

Structural model is to see set of one or more dependence relationships linking the hypothesized model’s constructs...

LETS DO IT... together
