Factorial Designs: Main Effects & Interactions

Omg this was SO helpful and straightforward! Do you think you can do a video showing a 2x2x2, 2x3, and 3x3 design?

Awesome video. Well explained!

I did some experiments with 2 Factors (Let say A and B) and 3 Levels (A1,A2, A3 & B1, B2, B3)
A1 B1
A2 B1
A3 B1
A1 B2
A2 B2
A3 B2
A1 B3
A2 B3
A3 B3
I have performed a total of 9 experiments. How can I perform a factorial analysis for this kind of experimentation.

Thanks mate!

This is such a great explanation! I love how you go over all possibilities based on some tangible examples. Thank you for making this

Thank you. great!

I'm taking research methods this semester and my professor does the least. He has no actual lectures, but will type them up and give us power points. I want to thank you for sharing this video, because this helps me out a lot.

I wish i could give you a hug 😭😭😭😭😢

Very good explanation of factorial designs! Great stuff man!

Thank you so much for the help! I'm in a class on this and the prof is useless, really appreciate people like you!

Thank you so much, I watched at least 100 videos and had no idea what they were saying BUT YOU MY GOOD SIR, HAVE DONE IT!! I UNDERSTAND!! I WAS CRYING BUT YOU HAVE MADE MY DAY!!!

Extremely helpful, thanks

The most simple description I've ever heard! Nice job!

this is quality content, thank you so much!

A question on my homework just shows the line graphs of a crossover interaction, parallel lines (no interaction correct?), and a spreading interaction. The questions ask for each one, how many main effects there are for each 2x2 factorial design. Does every 2x2 factorial design have 2 main effects? I feel like this question is made to trick me! Thanks for your video!

Thank you! This was a super clear explanation.

I was having a lot of trouble understanding factorial designs and why we use the table format to figure out the data but you explained it so well! Thank you so much!!!

Thank you! You've helped me so much!!!

Great explanation, THANK YOU!

Best explanation so far about interactions I have found, Thanks for this content!!!!

thank you so much! this was so helpful :)

this is so helpful in my research methods class thanks so much

Thank you for this. This helped me a lot to prepare for my Research exam!

That you expressed in best way!

Lord bless this man and this video.
Makes it so much easier to understand
