Understanding Reverse Scoring of Likert Scale Questions SPSS
In this tutorial, i will explain the Understanding Reverse Scoring of Likert Scale Questions using SPSS Example 1 Questionnaires that use a Likert scale (eg. strongly disagree, disagree, neutral, agree, strongly agree) for answering questions often contain some items which are to be reverse scored. For example, in a self-esteem questionnaire we may have some […]
How to Reverse Scoring & Reverse Coding Likert Scales SPSS
In this tutorial, I will explain How to Reverse Scoring & Reverse Coding Likert Scales Questionnaire SPSS Responses on questionnaires are often based on Likert Scale scoring (e.g. answers on a scale of 1-5). In some cases, there is a difference in the direction of these scales, for example an answer of “1” might be […]
Understanding Mediation Analysis
Introduction to Mediation Analysis This post intends to introduce the basics of mediation analysis and does not explain statistical details. For details, please refer to the articles at the end of this post. What is mediation? Let’s say previous studies have suggested that higher grades predict higher happiness: X (grades) → Y (happiness). (This research […]
How to do Harman’s Single Factor Test in SPSS
How to do Harman’s Single Factor Test in SPSS What is Harman’s single factor test? Harman’s single factor test is one technique to identify common method variance. If a single factor emerges or one general factor will account for the majority of the covariance among the measures then it is concluded that a substantial amount […]
How to Perform Confirmatory Factor Analysis (CFA) in AMOS
Confirmatory Factor Analysis (CFA) in AMOS Confirmatory Factor Analysis (CFA) is a special form of factor analysis. This is conducted after exploratory factor analysis (EFA) to determine the factor structure of your dataset. If in the EFA you explore the factor structure, here in CFA, you confirm the factor structure you extracted in the EFA.At […]
How to Perform Multi-group Analysis in AMOS
Multi-group Analysis in AMOS Multi-group analysis in structural equation modeling (SEM) is another form of moderation analysis but using categorical variables or grouping variables (e.g. Male and Female). This process is straightforward in AMOS as the grouping variable is already specified in the dataset.In cases where available data are continuous (e.g. Age) or ordinal (e.g. Likert […]
Fit Indices to Report for Confirmatory Factor Analysis and Structural Equation Modelling
In this tutorial, I present a comprehensive tutorial on the fit indices reported in the Confirmatory Factor Analysis (CFA) and Structural Equation Modelling (SEM) analysis, to test the fitness of the model and variable constructs. Present a discussion of the meaning of each fit index, its use and the threshold required These are discussed below: […]
