Moderator vs control variable

[Antriksha Negi]

Respected group members, 

Kindly guide me whether demographic variables can be considered as Moderator as well as control variable simultaneously? 

Also what is exact difference between these two? 

Thank you

Warm regards

1. Plz search previous post in group before posing the question.
2. Don't write query in someone's post. Always use the option of New topic for the new question. You can do this by writing to dataanalys...@googlegroups.com
3. Its better to give a proper subject to your post/query. It'll help others while searching.
4. Never write Open ended queries. This group intend to help research scholars NOT FOR WORK THEM.
5. Never write words like URGENT in ur posts. People will help them when they are free.
6. Never upload any info about National Seminars/Conferences. Send such info on personal emails. And feel free to share any RESEARCH related info.
7. No Happy New Year, Happy Diwali, Happy Holi, Happy B'day, Happy Anniversary etc. allowed on this group.
8. Few months back there was a facility for asking & sharing the Research Papers. Now there is no provision of asking for the research paper here.
 
Let’s make a better research environment.

Thank you sir for so much clear specifications of different between various types of variables. 

Warm regards.

Respected sir, 

How to compute mediation with control variables in

SPSS or AMOS. 

I am also attaching my model for your kind reference. 

Thank you

[Neeraj Kaushik]

Make model in AMOS

Check reliability and validity of every construct 

Impute to get the construct score in SPSS

Use Process macro to run Mediation using covariate option for the control var

Thank you for the inputs to both of you sir.

Thank you sir,

I don’t know but why every time I am uploading the Pic of my model I am getting this Mail Failure message.

“Hello Antriksha Negi <antriks...@gmail.com>,

The message you are sending is too large.  All messages must be less than 8.00 MBytes.””

I am again attaching the model and kindly suggest how to use meditation with process macro along with control variables.

Hi Antriksha,

My suggestions to you are

a. Watch the videos of Neeraj Sir on IBM AMOS and Process Macro. He has explained it very well.

b. You may watch his videos on mediation and moderation also.

In any case you find it difficult to share the image due it's large size, then it is always better to save it in the Google Drive and share the link. It is visible and observable also.

Once you complete watching his videos and taken notes from them, you will be in a position to know the process. You might ask him "to the point" questions to him in future.In acse he is taking any workshop on the same topic in future, you may attend and participate also.

Thanks and regards,

Ramani Swarna

Sure mam, 

Thank you so much . 

But after watching his videos I am writing this query here.

 As far as I was able to search, 

I didn't found any such video where mediation is applied in case of 2 or more IDV along with control variables in DV. 

Kindly guide me. 

Warm regards

In the recent workshop, Sir literally went out of his way to explain the differences between AMOS and SMART PLS. I need his approval for sharing the differentiating Table as discussed by him. Secondly, he made it very clear that no control variables in the case of AMOS and PLS SMART. 

Antiriksha, there are two points that you are highlighting in your query:

a. What is the scenario when the variable is being controlled and you are checking the status of other variables? In this case, you are controlling a variable in order to find out the contribution of other variables. 

b. What is the impact of the mediating variable? In this case, it is the mediating effect of the variable between two variables. 

Both the scenarios are different. 

Thanks and regards,

[Ramani Swarna]

Try to understand about the variables:

a. Relationship between two variables viz. IDV and DV. In this case, there may be many IDVs and DVs. With Factor Analysis, you are able ti check out the contribution of each variable. Now with the help of the Control Variable, you will check out if the other variables will be able to sustain or not. In other words, you are checking the contribution of other variables by controlling one of the variables with the highest value. 

b. Moderating Variable- This variable clearly checks out the relationship between the two variables.

c. Mediating Variable- There is a relationship between two variables say A and B. Now you will check out to see the relationship in the presence of another variable C. Check the values between A and B, A and C and C and B. 

Sir has explained this very clearly in his video titled "Different types of Variables".

Thanks and regards,

One more point that may be highlighted is that

You need to check whether the control variable (Moderator in your case) has a significant effect or not.

Mam, 

My model is as mentioned below

1.  A, B & C are IDV's

2.Z is a DV

3. X is a mediator between A & Z, B&Z and C &  Z respectively

4. E & F are control variables controlling DV ie Z. 

Now my question is while estimating mediating impact with control variables, whether

1. I should compute  the relationship one by one 

Or

2. All the relationship I need to run all together. 

If you have any such video or link for any such model or relationship please do share. 

I think that way I can get more clarity. 

Thank you for your inputs mam. 

Warm Regards

Dear Antriksha,

I will suggest you to go through the book SEM by Berry or by any author.

Or google the model of ur interest. Many research papers are there having such models.

Ramani Ma’am and Neeraj Kaushik sir explained the concept very well.

But still if doubt is there, u can refer to book.

If u read by urself, ur all fundas would be cleared.

To answer ur query, run all relationships together.

Also,

If control variables are having insignificant impact on DV(Z), u can drop them if DOF of model is creating a trouble (Hair et al, 2014; Gaskin)

**But, first run all relationships together**.

Neeraj Sir explained this thing innumerable times.

Thank u

Dr Apeksha

Dear AN

As already written by Ramani mam and Apeksha, there is no provision of handling control vars in a mediation model in SPSS, AMOS or SmartPLS.

Still, I recommend you to work on AMOS and include control vars in your model.

Ideally, we must get statistics like Hierarchical Regression, to get the real effect of IDV after controlling for the control vars, but there is no such thing available in any software.

So, we do introduce control var and consider that whatever effect if there of IDV or mediator, that is considering the presence of control var.

You may refer the video of Prof Gaskin https://www.youtube.com/watch?v=IviYrSxitPs&list=PLnMJlbz3sefLdYnz7TysHKrMBby7igpV9&index=9

Saw the video. 

Very interesting but Complex relationship. 

If possible kindly share any research paper having such relationships.
