Thank you so much Mike. I have been looking for videos that explains how to interpret my pca outputs in simple terms but with no luck until I came across your video. So informative and easy to understand. Definitely recommending to my friends

Hi Mike! Very useful video here. Yours is definitely one of the most resourceful and clear PCA videos I have ever come across (with reference too - which is awesome!) Highly recommend this video!! Just one quick question: when I was doing the rotation component matrix, some of the items appeared do not contribute to any component at all (e.g. the item instructor being sensitive to students does not have any number to either component 1 or 2 when I set the suppression value to 0.4. Does it mean that I have done something wrong? or I can just take out that item when I consider naming my components?) Thank you so much! :)

[@mikecrowson2462]

Here there. When running a PCA (or EFA for that matter), you often will have items that do not meet loading criteria. This does not mean you did anything wrong. Those items that do not do a good job of defining a given component are basically not used in the naming of the component. If you are forming scales based on the pattern of loadings, then you usually just include those items that met the loading criteria (and that were used in the naming of the component). Cheers!

Hi everyone, be sure to also check out this video on PCA using the open-access (freely downloadable at www.jamovi.org/download.html ) program, jamovi: kzbin.info/www/bejne/nH3IiXh9Z72Ihqs

In output, I am not getting my rotation matrix coz it says only factor was extracted The problem fixes when I change eigen value from 1 to 0.5 in extraction. Is this legit way to do....?

Mike Crowson! Can you give the short description about this dataset? What was the purpose of collecting this dataset? I'll be very thankful.

[@mikecrowson2462]

Hi there. Actually, I didn't collect the data. I downloaded it at: stats.idre.ucla.edu/spss/output/principal-components-analysis/ The data appears to be instructor ratings, and there's a better description of the individual items at: stats.idre.ucla.edu/sas/output/principal-components-analysis/ hope this helps!
