Factor Analysis in SPSS - How to [part 3 - rotation and interpretation]

Sometimes it's hard to use SPSS. Here's an easy way to rotate and interpret - the final phase - a factor analysis in SPSS in few simple steps. check out part 1 (how to make) and part 2 (interpretation) -- Às vezes é difícil usar o SPSS. Neste vídeo pode fazer a rotação e interpretar - a parte final - numa Análise Factorial em alguns passos simples. Não se esqueça de procurar também a parte 1 (como fazer) e a parte 2 (interpretação)

Crucius, your tutorial is great! Based only on your tutorial and my understandings of SPSS, I actually was able to perform quite a decent factor analysis (judged by my thesis supervisor, it was better than most students' first attempts). Thank you! One thing I would like to indicate is this: if you save your results from the factor analysis as variables, you can actually use the results to perform a regression analysis. It would be nice to add this to the tutorial.

@Fietsband1900 i'll be adding some more tutorials and i'll include one on Regression Analysis. Only it was not intended when i was doing this tutorial and, as such, didn't include in the video. Thanks for the tip, and i'm glad it helped you! If you have requests for spss tutorials, you can PM me!

I just want to say that your video saved my life.  As a person with very little stats background doing a master's thesis, this is incredibly helpful.

@aMuuuuuuuu i have to say your commentary made my day. it's great my videos helped!

Hi Crucius,

If an item has close loadings in different factors, what factor do you think they should be assigned to? Is there some value cutoff, like if the difference is greater than 0.3 it goes to one factor over the other? Or do you simply discard?

[crucius]

well, it actually depends on the investigation...if an item has close loadings in different factors it means that that item is ambiguous, so you can say that either is good to both factors or not good enough for any. you CAN put that item on both factors, but what's the point? usually, i just discard it...but i'm no expert on these things, so the best thing is to find some good SPSS manual (there are some free on the web)

thanks for the interest in my videos!

A.S.

Very helpful, thanks :)

@crucius thanks for your quick response. I wasn't really looking for a tutorial on regression analysis (mind you, there are plenty of those available), I was merely indicating that after all this work you can actually save your factors as variables. In my case for example, it would be insane to test all my constructs (30) using a regression analysis as the sample size is not nearly large enough (30). As I cannot increase my sample size, I will be using the factors (7) for my regression analysis.

Sorry meant Crucius.. Really sorry

Hi Circus, do we include the negative loadings as well uder the factors or just exclude them? Thank u
