Factor Analysis Using SPSS

[@8shelbyg]

Factor analysis is a pretty complicated concept for me to grasp, so I like that this is explained in video form. If I start to get lost, I can rewind and figure things out for myself, whereas if this were a regular lecture, it would be easy to get lost in such a difficult concept. Showing this in SPSS makes me feel like I would be able to do this myself, something I thought was way above my skill level.

[@Asher.slay1]

I wish this guy was my lecturer... Explanation was better than my university!

[@farahbahgat2360]

Thank you so much Dr. Grande. Wouldn't have made it through grad school without your videos.

[@DrGrande]

you are quite welcome

[@dominikar4969]

I have finished my Master’ and doing my PhD only thanks to these videos. Thank you Dr. Grande!

[@shelleyswift]

Thank you so, so much for sharing your knowledge and expertise. I have basically taught myself all of the stats required for my research using your videos. I love your delivery, clarity and depth of knowledge. Thank you!

[@mks6148]

My Business Intelligence Professor in college was so passionate and well versed with SPSS! Great tool.

[@vidaadansi5633]

Great step by step presentation of using SPSS. It's a lot to learn and master using SPSS but Dr. Grande takes his time to explain the process very well. I have used SPSS before and do I know it be can be used to determine correlations of items. I definitely have to watch again and again in order to remember the process. Great work.

[@Rozemarijn97]

Great, this is a very clear (you could say even slow) explanation of factor analysis, so it is perfect and easy to understand even if you are fairly new to the concept.

[@MahtabAlam-uf8db]

This must be the third or fourth time I watched this video in the past 1 year and I think I am finally beginning to understand factor analysis. So, we use it to validate our self-made constructs (which I totally avoid).

[@cherylchance904]

This video was very informative and helped to refresh my memory about how to interpret the data. Using 100 participants helped provide a better understanding of the different potential outcomes as well. I also appreciated the definition of the term factor loadings as I was not familiar with that term.

[@sammiejo6344]

The section in the book on Factor Analysis is very very brief. Dr. G does an excellent job providing detail explanation about Factor Analysis, and applying it with SPSS.

[@aud15chou80]

A Od I agree very detail explaination

[@andrewlightfoot1560]

I'm usually alright with stats, but this definitely way over my head! I did like the explanation of how the factor analysis breaks down the relationships between variables though.

[@nilanjanNM37]

The video is immensely helpful Dr. Grande.....

[@joanagamagama5099]

Thank you so much!! Your clear and thorough explanation made my analysis for my master thesis not seem like a nightmare anymore!!

[@ammu9810]

I appreciate the step by step teaching going on in this video. The topic is difficult for me, but I feel confident that it I could accomplish it with the use of this video as a directive. Great video!!!

[@pedro-ivannavarronaranjo6682]

Great video, clear ideas and step-by-step process to perform and understand factor analysis

[@alexisklair3164]

This video was very clear and easy to understand. I appreciate the in depth explanation of factor analysis with a real example/data set that we can work through while understanding. It was easy to see the real world application for using this function. This was my first experience with spss, and have mainly used excel. This is the first time seeing a correlation matrix like this, although it was easier to understand when dr G went through and explain what to look for when reading the matrix. A good reminder about what constitutes a strong and weak correlation. I also learned about the determinant which I never knew before. Good video!

[@Kryptic_Karma]

Woah. Didn't realize you made these types of videos. Currently using SPSS to run a few analyses on different factors that are correlated with a person's expectancy of success so that I can include the information on a report.

[@Adnann1234]

that moment when you watch the explanation during lecture and youtube makes more sense..

[@jibrannaeem6492]

it always make more sense .. trust me

[@aud15chou80]

Great step by step description of how to use SPSS, Well explained.

[@spk.777]

No words to say thanks to such a wonderful teacher in you sir

[@izzadurrabajerai7234]

I know your name is Dr. Grande, but at this point, I owe you Starbucks Trenta big time! Thanks for this!! Great help with my SPSS practicals! :)

[@amandayarn5160]

In past videos using excel, I was better able to understand concepts and equations because I could physically replicate what you were doing in my own excel sheet. Since I do not have SPSS, it was harder for me to wrap my brain around. I think the video was very informative but, I am going to have to watch it a few more times!

[@alexisklair3164]

I agree that it was hard to understand with no previous knowledge of spss, and not being able to follow along on my own (dont have access to spss). I think it was helpful and clear to understand the steps, however i dont know that I fully understand the subcomponents/terms within each tap/step. will definitely watch again,as you said

[@raymondschenk9964]

Excellent primer! You helped me decode this process in a very meaningful manner.

[@milicajovanovic7645]

This is a very good video and sums up everything that's important perfectly.

[@DrGrande]

Thank you!

[@juliecampana2860]

It's good to know that we have many useful tools to help us complete a factor analysis of a data set. This tool looks like it would be really helpful when working with large sets of data. Hopefully, I'll get a chance to become more familiar with SPSS in the future.

[@geobnks]

This is the only aay I have been able to understand this topic - thanks!!

[@DrGrande]

You're welcome, thanks for watching -

[@tahseenmirza1482]

@@DrGrande can i get your email ? i have some questions

[@caitlinfields3175]

This was a good video to have visibility on how factor analysis actually works. Although, the specific on how to do this is quite confusing, this video provides a general idea of how factor analysis comes together. It was interesting to see how to identify the correlations between items. I will need to watch this video a few more times to learn how to do this on my own.

[@laurashine7134]

This video was informative and valuable for the learning process; however, using SPSS and Excel are areas that I find to be quite challenging. I have never used SPSS and would need lots of practice. I do appreciate how the explanation was described in a step by step formation.

[@kendallwilson7319]

I agree, I like the step by step formation and if i do ever use SPSS this video will come in handy for it. It did help me understand the concept better but I think I would have understood it even more if I knew SPSS.

[@reggierosario4708]

It was certainly helpful, Dr. Grande ! Thanks a ton !!

[@brittanyrio3619]

I like this video because it does take everything step-by-step. It is a bit hard for me to follow along however, because I am not familiar with SPSS. Overall can't help but feel like hoping I won't ever have to use this! I do, however, understand that this is a way to look at variables, and understand the purpose of using it in research. A helpful tool for those who know how to use it.

[@8shelbyg]

I agree about the SPSS. It is kind of a complicated program and not really too similar to anything else most people use, so I think this kind of video can be hard to follow because if you have never practiced much with SPSS, there is no foundation, so it can be hard to follow.

[@alexisklair3164]

I agree. the step by step is helpful but darn is still stuff complicated sometimes. this was the first time I had learned this in depth and feel like i understand factor analysis a little more, but think that I am still not understanding some of the terms/constructs within each step/tab that he did.

[@nickberenato3131]

Yes Brittany and Alexis, Dr. Grande makes it sound so easy and I still found this video hard to follow. I do understand factor analysis a little more also but think I need to look at the other video he suggested.

[@juliecampana2860]

Absolutely Brittany. For those who have used this tool before, I'm sure this analysis makes a lot of sense. Unfortunately, for the rest of us, the configurations of the data and how to use data with this program seem really confusing.

[@angiemorales8481]

I agree because I am not familiar with SPSS either but the video did an excellent job of going over the information step by step.

[@Anesidemus]

Many thanks for posting this video. Very easy to understand and helped me prepare.

You're welcome!

[@rachelhemming15]

Fantastic explanation. Much better than uni

[@genevabarnes7402]

I really enjoyed the step by step information that was provided. And I have worked in Excel quite a bit. The SPSS to compute factor analysis looks extremely challenging. I am definitely going to have to watch this several times to maybe get some kind of understanding from it.

[@andrewr6433]

Yeah the format of being step by step in this video was very helpful. I do not feel like I missed a step or that he went too fast for me to follow.

[@qwertical]

I don't always run a factor analysis, but when I do I check out Dr. Todd Grande's vieos

[@mmolavi1663]

Thanks a lot Dr. Grande. Useful explanation.

[@angiemorales8481]

The video was very clear and easy to follow. I did watch it several times and I am still not 100% percent sure if I have truly grasped the whole concept. It would be interesting to have a hands on approach which might help make the information click.

Update: thanks for the like Dr. Todd. I've learned a lot from you videos about the Big Five Personality. However, I would still prefer if you spoke a bit louder and showed more enthusiasm while explaining to make the learning experience more engaging and enjoyable. Thanks! A very good explanation but I wish if you spoke a bit louder.

A lot of information to digest, I will have to watch this quite a few times to get a clear understanding.

[@ushalincoln2546]

Though I would probably have to watch this clip numerous time if I were to run a factor analysis however, this clip does make a lot of sense of how one would use it to see how variable relate to each other. This concept would probably be very useful it you were looking at numerous variable in a study and wanted to see how each of them related .

[@alexdeloach6472]

What I like most about incorporating these videos into our class is that we can go back and rewatch them. It has definitely proved helpful for me numerous times. This video was easy to understand and detailed.

[@atomikjames]

[@Shadowofromefanatic]

Hi Dr. Todd. I'm curious what the selection variable box is for during the set-up screen. Could you tell me?

[@ELdASenSei]

9:00 became interesting for me I am having the issue where the determinant is ,000. but dont know if that is below ,00001. And if the items are highly uncorrelated with eachother this will mean that I have a problem as it seems that I have a low reliability with these items. Furthermore, I am not getting any info on KMO and Barlett's test. I did selected it in descriptives.

Hi! Dr. Grande, I just wonder where did you get the information about the multicollinearity at .8 and above from? Thank you so much for your advise.

The book barely talked about factor analyzes, so I appreciate this video. I must say tho that I am very lost in this. I will certainly need to watch this video again. I still do not understand how this factor analysis is done... :(

[@jessicamcnemar182]

I am with you on this one Danni! This video presented many things that were not in the text. I feel like I need a whole class to go over these things and understand them.

It is nice to have these videos supplement what is covered in the texts.

Thank you Sir. I have a query. What does Component plot in rotated space denote in spss? Thanks

[@kostasandrio3069]

How do you make the correlation matrix for the extracted factors?How do you create the values for the new variables that you extract?

[@samuelvanlalruatakawlni6207]

Suppose on a 10 item scale (i.e a subscale of a larger scale), 4 components was extracted with diverse loadings (widely spread) among the items. Shall i retain the original items or remove those items that are alienated from others. Please

[@jyotijibankhisha7565]

Thanks for your lesson. I understood the concept. However, one of my Eigen Values is 20. What is meant by this?

[@Renssu]

After discovering a correlation between items above 0.8, what would be the correct way to deal with this 'too high' correlation? Average the 2 out into a new item?

[@andrewr6433]

Pretty much agree with everyone else is that factor analysis is an interesting process and definitely useful, but I hit a block with the fact that I have never used or even played around with SPSS. I do find it pretty easy to understand the Excel videos though

[@Djorouh]

Great explanation. Thank you so much.

[@juajune5519]

Hello Dr Todd Grande! I just conducted this Factor Analysis and I ended up with 3 components. However, I need to measure the effects on this variable, and measuring the effect this variable has on another- so having 1 would be a lot better. Do you know what I can do to fix this without deleting too many items?

[@ojl6475]

I have a question. When I do oblime rotation, do I have to choose "Maximum likelihood" method or still "Principal components" method?

[@kendallwilson7319]

While these videos are very informative and really do help me understand these concepts better, the videos in SPSS are a bit harder for me to wrap my mind around because I have never used SPSS and I can’t apply this information as well as I can to excel since I have used that program and can practice in it. The video still helps me understand the concept though because he does explain all of the variables and processes in so much depth. Especially when you see the outputs and he explains the results.

[@sammiejo6344]

I too agree. I think it would help if we were doing the steps ourselves as Dr. G is explaining it. He makes it look really easy, but there are so many components to it, that it can be a bit too much.

[@danielamoore1412]

A Od I agree. I think it would help if we had lectures in class at least up till chapter 6 (cause they are more stats based) so that we could try doing things WITH Dr. Grande. I don't like this kinda class to be online or "independent learning". Sometimes I get frustrated because I do not understand the material... I barely followed this video.

[@laurashine7134]

The text book only briefly touched on factor analysis but this video did take the concept to another level. I have never used SPSS but watching the step by step example that was delivered was helpful.

[@robertrobertsjr.2245]

Kendall, I agree with you about how informative this video is and also understanding how to get the results using SPSS. I think would help if we did some examples in class, so that we could see in done in front of us. Practice, practice, practice is what I would have to do to learn.

[@amandayarn5160]

I completely agree! I think that I was able to understand the videos in research because I was able to replicate them in Excel. Since I can't do that with SPSS, it is a little bit harder for me to comprehend and follow along.

Can I use a dataset with multiple gaps to conduct factor analysis?

[@moltobhai]

Thanks for the video. This will certainly be helpful for my exam tomorrow. But, I have one question... not sure if its too obvious or "too wrong"... after I group the variables in factors how do I assign values to these factors, as on my survey I had collected data for the variables, not the factors? Or is my line of thinking absolutely wrong in this concept?

[@talhaiftikhar6195]

Please also add the rotated component matrix that also makes sense how to handle it. Thanks Dr.

[@UDrivin]

Once you have a suitable factor solution and you wish to look at correlations I'm told you need to create standardised factor scores that take only positive values. The method I used to do this was adding a constant to each factor, and taking the fact score away from the constant when the factor was measuring in a "negative light" so for example a factor measuring antisocial tendencies was transformed to measuring sociability. However, when I produced correlations with age none were significant. Have I missed a step or made a mistake?

[@daiveellis1]

Am I right in thinking that this is an example of Exploratory Factor Analysis (because nowhere does he tell SPSS that 1-5 are meant to be one factor etc)? And not Comfirmatory Factor Analysis.

[@javeda]

Dear Dr. Grande, Can we run moderation and mediation analysis with a dichotomous binary variable as an outcome variable?

[@slumpighet]

I don't know why people complain that factor analysis is hard. It sure is easy without crossloadings! ;)

[@drjaycool3393]

Hello, I was watching your video and somehow started thinking about another issue unrelated to factor analysis but thought I would ask you advice. I have survey results that include a PRE intervention condition and a post intervention condition. It was supposed to be a paired samples t-test but when the results came back there was no way to pair up the scores. So I no longer have a paired samples test but I also don't have an independent samples test as the groups are not independent. What test would you suggest? Overall, the people that answered the PRE and POST survey are the same people just not paired up. They are matched in other ways - they are all nurses and also all fall under another category (filed of study). My dependent variable is ordinal (likert scale). What are your thoughts. I have already run a sign test, Wilcoxon signed ranks test, Chi-Square test of independence, and a paired samples t-test. All of which produce the same results in terms of significance levels. Thanks, Jeff
