Questions that you can go for Moderation Analysis

-

Do girls experience a greater increase in confidence than boys after an intensive math intervention?

Tips: Get literature that spell out inconsistencies between boys and girls. Some scholars told boys are better but let say in the Malaysian context, people are not sure about which gender become greater increase in confidence after intensive Math intervention. This can be studied using gender as moderating variable whereas greater confidence as DV while Intensive Math Intervention as Independent variable    

Does the program work better or worse in Urban areas as compared to rural ones?

Tips: Here program effectiveness as DV while program implementation as IV, with population differences as moderating variable. Researcher wants to see the specificity of effect. Researcher segregates the group to urban and rural by looking at how urban and rural people react towards the program implementation. By doing this, researcher can identify group that has greater effect or no effect in which there is exactly the truth lies. If intervention effect is positive at all levels of the moderator, then it is reasonable to deliver the whole program· If intervention effect is observed for one group and not another, it may be useful to deliver the program to the group where it had success and develop a new intervention for other groups

Is program impact higher where implementation fidelity was greater?
Tips:  Researcher is adding an additional experimental factor that is implementation fidelity. Implementation fidelity is the degree to which an intervention is delivered as intended and is critical to successful translation of evidence-based interventions into practice. Diminished fidelity may be why interventions that work well in highly controlled trials may fail to yield the same outcomes when applied in real life contexts. The additional factor is picked so that an observed relation is differentially observed across subgroups. Moderation analysis provides a way to whether intervention effect has similar effect across different group

Does the informational intervention about health prevention operates more effectively in communities with localised health services?

Tips: Moderation analysis provides a way to test whether an intervention has similar effects across sub-groups under communities with localised health services. The consistency of an intervention effect across subgroups demonstrates important information about the generalisability of an intervention.

Analysing and Reporting Moderating Effect

-
First researcher should focus on the significance of the moderating effect (Z) To clarify, it is possible that a moderator variable (M) may or may not have an effect on the dependent variable (Y) Thus, the decision as to whether there is any moderating effect should be made based on a significance relationship between the moderating effect (Z) and the dependent variable (Y)     Second , researchers must calculate and report the effect size (f 2), and how much it contributes to R2 as a function of the moderator Only a few software packages (e.g. Smart PLS3.0) calculate f 2 by default For other there are online spreadsheets which can be used to calculate effect size (see: http://statwiki.kolobkreations.com ) Lastly, researchers must execute and report a simple slope plot for visual inspection of the direction and strength of the moderating effect SmartPLS users can check out a simple slope plot under ‘Final Results’ and ‘Simple Slope Analysis...

Narrowing Down Research Topic: To narrow down your topic / focus area, you could ask these kind of questions: Whom for you doing the research? (Specific populations / Stakeholders) What are the factors you have taken for a research? is it relevant, contemporary or not? ( Relevant topic ) Where exactly you want to do the research? (Specific geographical area) This particular time when you do the research, is it relevant or not? (Specific time period) Why the issue occurs?  Example: Topic: Research Topic on Eating disorder Who –  Initially this topic is too broad, to make it narrower, we opt for population that we can focus on. Social demographic factor like: race, gender, age which are connected with eating disorder. So, the topic can be eating disorder in elderly female . You are connected gender, the age and disorder. We are fine tuning this problem into this factor.   What types of eating disorder -  2 types of eating disorder, ...

Approaches For Moderation Analysis

-
When performing statistical analysis using structural equation modelling, specifically in PLSSEM, there are several approaches for moderation analysis, including: Product- Indicator Two Stage Orthogonalizing  Prior to that, researcher must identify his or her theoretical frame falls under reflective construct or  just formative construct. Depending on researcher’s objective, he or she can choose any of the three approaches. 2-stage approaches has highest power, it is the most likely approaches to create significant attraction. It is recommended to make use of 2-stage approaches and make analysis. I f researcher has smallest population, he or she suppose to use orthogonalizing because the interaction effect size is the most correct and it maximises explained variance in his or her dependent variable. Product indicator approach has no particular advantage but still if it is formative construct can use product indicator approach Formative cons...
