EXCELLENT Dr Kristin Atchison...Delhi (Research Scholar)

[@Huedtunes]

Completely overthought having one main effect with no interactions until seeing this video, thank you so much!

[@locustphysalis3300]

Once you understand it it’s actually pretty straight forward, thanks!

[@arianaehtesham6052]

You are amazing Dr. Atchison!

[@vinniedeoliveira2641]

Hello, is there a video on the tests we could do after detecting the interactions? For example, if ANOVA showerd interaction effects, what could I do afterwards? cheers

[@alexs.5107]

Thank you!

[@MrAlButler1]

Thank you. Very clear explanation!

[@mikelegare4502]

The examples used in each study, are themselves, interesting, which makes the teaching easier to adhere to.

[@wyclifeindiaka1124]

Thank you..

[@mikelegare4502]

Better teaching than I am receiving from my own university.

[@N12Gautam]

I started understanding from the televsion program example

[@junitalynn3815]

Nice tutorial! But I didn't get the result from the first example in 6:11. Why the highest grade means 8 indicates the highest dissatisfaction while the highest score in book means which is 6 indicates the highest self-esteem? What does the score mean? Body dissatisfaction score or body satisfaction?

[@2010ohmygoodness]

Great job on explaining this...thank you so much! : )

[@aryanshahabian5108]

Very informative. Thank you Dr. Atchison. How can I cite it in my dissertation? Shall I put a link to this video with your name? Or, are there specific papers you would like to be mentioned as references?

[@mikelegare4502]

Excellent teaching

[@nidhiarora477]

Thanks.

[@fengyuwen4072]

Thank you! That is very clear and easy to understand!

[@georgiahutto-friman7279]

Thank you so much! Great lesson

[@krystalgangi]

can someone explain the reasoning behind the example in 20:25? and why there is no interaction?

[@DrKristinAtchison]

All we have there is a main effect of B. The easiest way to explain it is if you were to draw a line between the two "b1" bars in the graph and another line between the two "b2" bars, those lines would be parallel. Parallel lines indicate there is no interaction. Also if you just look at the data in the table, you can explain the difference in the marginal means (8 vs 12), by the main effect of B alone. Hope that helps!

[@makhosazanethandeka4228]

thank you

[@nerdstadistica]

Excellent lecture! I have just one question, what do the numbers mean in the table in 6:25? Are they some kind of self-steem score? or body dissatisfaction score? If it's the last one, the mean effect of the barbie book should be greater than the others, shouldn't it? Thanks in advance!

[@num4328]

Hi Valerie, I know you've posted this 3 months ago, but yeah, I was wondering the same thing. If higher average means higher body dissatisfaction, the average book means for barbie version should be the highest, but it was in fact the lowest out of all three (4) compared to Emme (5) and Neutral (6) Did you had it figured out?

[@Han-yh5jc]

From which book is this?

[@DrKristinAtchison]

A combination of resources was used to create the video. Depending on your needs Gravetter or Morling both have good texts.

[@vanadydaniels416]

Very helpful instruction.

[@DrKristinAtchison]
