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.
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!
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.
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.
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.
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.
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.
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!
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).
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!!!
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.
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.
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.
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.
"Grief is not passive but active, grief reveals and challenges while it deals with the facts, it lends itself to truth in a way no other emotion can, it identifies all of the participants in tragedy and allows them their role in the universe." Quote unknown. thanks
thanks for the video! do i need to take the logs from the original data before starting? and then but the log at "item 1" etc or do i just use the original data that i collected?
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.
I like this video (even though ones like this are tough) because Dr. G does take it step by step. I do think that it is nice to have tips given for how to do certain things and how to look at variables in a new way. for example, Dr. G tells us that it would be quite unusual to have variables that do not correlate in our filed (usually) and that was not only good to hear, but reassuring. Thanks!
I too appreciate the fact that he walked us through the process step by step. I wasn't able to follow much tho. I will have to try watching it again later on to see if it gets a bit better.
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?
I tried to adapt the knowledge from you video to my data, firstly tested factorability with KMO and Barlett`s test of sphericity, which indicated that Exploratory factor analysis is possible. However my factor structure with absolutely messy. Meaning I had lots of Cross loadings, low correlations and table results were different than scree plot suggestion. Could you please make a video, showing how to deal with something like that, with no perfect data. Anyway thank you so much for your videos!
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
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.
The text does not provide great detail regarding factor analysis, so this is an eye opener. The explanation between what is an acceptable determinate (greater than .00001) and multiple correlations (.8 or greater) was really helpful, even though I still feel lost as SPSS.
I agree Jessica. I think these videos have served as an excellent add on to the basic descriptions to the text. Perhaps Dr. Grande should pursue teaming up with the authors of these text books!
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!
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
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.
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.
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 .
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.
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.
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.
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.
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.
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.
Hi Dr. Grande. First things first. I thought you should know that I got a 1st on my quantitative research because of your videos! So thank you very much for putting these up, with them I wouldn't have understood the numbers that my quantitative tests gave me in my project so THANK YOU! Secondly is there any way you could explain to me what Factor Analysis is. I've tried everything to get it and I'm not sure at all to be honest. What does it mean to see how the factors load together. What is a factor exactly?
Hello Dr I am really pleased to see your informative lectures. I have a question regarding the cut off value for correlation matrix determinant which is said to be 0.0001 in this video. How you can determine that cut off value. Second, your video is lacking information on the interpretation of the correlation (Sig-1 tailed) test scores. if 0.05 is the P value than the assumption we have is the P value less than 0.05 we will reject the null hypothesis (A=B) which is in contrast to the correlation results. for example two of my variables have a value of 0.754 and P value 0.000. With correlation, this shows two variables are 75% resembling each other and P value is saying they are significantly not equal. Please elaborate it for my understanding. Thanks Salman
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.
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?
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
I wish this guy was my lecturer... Explanation was better than my university!

you are quite welcome

I have finished my Master’ and doing my PhD only thanks to these videos. Thank you Dr. Grande!
Thank you Dr Grande! This was incredibly helpful :)
that moment when you watch the explanation during lecture and youtube makes more sense..
it always make more sense .. trust me
A really excellent explanation of using SPSS to run a factor analysis (PCA)
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.

Thank you Dr Grande 💙 I'm considering doing a f a of my mock psychometric scale data set for my MSc coursework x
The video is immensely helpful Dr. Grande.....
Great step by step description of how to use SPSS, Well explained.
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).
Thank you so much!! Your clear and thorough explanation made my analysis for my master thesis not seem like a nightmare anymore!!
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!!!
I don't always run a factor analysis, but when I do I check out Dr. Todd Grande's vieos
It was certainly helpful, Dr. Grande ! Thanks a ton !!
Excellent primer! You helped me decode this process in a very meaningful manner.
do continue producing videos like this. thank you for your effort. help me alot!
Thanks Dr.Todd for your well interpretation
Dr Grande thank you for sharing your knowledge !

Many thanks for posting this video. Very easy to understand and helped me prepare.
A lot of information to digest, I will have to watch this quite a few times to get a clear understanding.
This is a very good video and sums up everything that's important perfectly.
Thank you!

This is quite detailed and useful in running factor analysis.
No words to say thanks to such a wonderful teacher in you sir
Thanks a lot Dr. Grande. Useful explanation.
Thank you. this really helped me with the understanding of factor analasis
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! :)
You saved my coursework! Thank you!!!
You're welcome!
Muchas gracias, funciones super bien!!!!
wow..good explanation and well composed..thank you.
Really helpful. Thank you.

You're welcome and thank you for watching -
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.
Thanks! Very useful!
I think it's safe to say that Dr. Todd is the real MVP
This is the only aay I have been able to understand this topic - thanks!!
You're welcome, thanks for watching -

What does this mean ?
Very useful explanation! Thanks a lot!
You're welcome - thanks for watching.
Thank you so much!!!
Hi, thank you for your video. I have a question, concerning the extraction of variables and observations on the same plane! How can I do this please?
Hi Dr. Todd. I'm curious what the selection variable box is for during the set-up screen. Could you tell me?
thanku sir iwant to the detail theory of factor analysis with little bit variance in aspss package thanka u

Me watching tutorials on youtube the night before the exam cause i understood nothing in class 👁️👄👁️
Thanks, Dr. Grande!
Thank you so much. It's easy to understand.
You're welcome.
I thought this was a great video in showing the groupings together and the similar factors to stick together on the similar construct.
Please also add the rotated component matrix that also makes sense how to handle it. Thanks Dr.
Thank you sir !! that was very helpful !!!

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

Sir, can you give me the dataset file so that i can practice...
Thanks doctor for the good explanation
You're welcome - thanks for watching.
Thanks, great video.
You're welcome. Thank you for watching.
This is really really good. Please, I need your clarification as to whether this is a confirmatory or exploratory factor analysis.
Me too lol.
Thanks for your lesson. I understood the concept. However, one of my Eigen Values is 20. What is meant by this?
I have a question. When I do oblime rotation, do I have to choose "Maximum likelihood" method or still "Principal components" method?
thanks for useful explanations Dr.Grande, but the sound level is terrible, ı can hardly hear.
i'm also
How do you make the correlation matrix for the extracted factors?How do you create the values for the new variables that you extract?
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 DOCTOR TODD HOW CAN I SUMMERIZE IF ONE indepedent varable more than two dimensions ? how i can anailze it?
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?
Thanks!
