This tutorial series on the two-way AONVA, including SPSS, is a LIFE saver. Very well done!

The amount of work you dedicate to each video is admirable! Thanks to your videos, ANOVAs are MUCH easier to understand!

Thank you for the time and effort you put in. It really shows in the high quality and concision of your videos.

the best tutorial i've seen till now!!! Been looking for months! Thank you!

Thanks for explaining it so well..I could not find a better video on youtube explaining how to perform ANOVA test in SPSS

This was great ! I have a marketing research project due tomorrow and I have to critique the former group which chose a t test I will conduct an anova Test, this was so much help!

Always nice to hear my videos are helping students learn.

What a wonderful resource ! Thank you for all the hardwork that you have put into this.

Fantastic video, best one I've found so far. Really gonna help with my thesis!!!

Thank you so much for the series provided, It is really easy to follow and absolutely helpful.

Your videos are brilliant, I was completely lost until I watched this!

This is a good youtube, simple and easy to understand. Thank you!. Have a nice weekends!

Incredibly clear and helpful, thank you for making this video!

You deserve and award for explaining in such an easy way. Thank you sir

No explanation is greater than this. I have already shared! Thanks..

Thank you. You make this sound easy. Your narratives help make sense of all this.

Your videos are always so amazingly helpful. You got me a first for my summer exams! Do you have a video about how to deal with assumption violations on SPSS? I am confused about what to do when you have a violation of normality and your videos are always so clear

You explain slowly and clearly.. I appreciate your understanding..

you are a lifesaver ! Thanks so much for simplifying stuff down.

This was a great video. Thank you for being so thorough.

You are a life saver!

Excellent explanation and I really appreciate for making such kind of video.

This was so clear and easy. THANK YOU!!! It makes so much sense now.

Thanks! I use a variety of different software including photoshop, illustrator, HTML5, Final Cut, GarageBand and a few other products. Each video takes me a long time to create. My rule of thumb is each minute of video takes about 12 hours to create, so a 7 minute video takes me about 84 hours of development time.

Thank you for posting these videos. They were very helpful. You have great sound on these videos and the pace was perfect. Many thanks!

concise and explained simply... great job

I am truly grateful about how you explained and tried to simplify this topic. The videos, those I have viewed, are all very very helpful. Persons, like me, who are not so into statistics can benefit from your wisdom. Thank you so much and more power to you!!!

thank you so much for the best explanation of 2-way ANOVA!

thank you for the series! :) helps a lot to understand

absolute legend, this video helps so much. Thankyou !!

Thank you. It is a great video. I like the way you explain the main points.

Great videos sir, best I have seen . Thank you

true to the YT name, you are making this fun!

Great. Really clear. Do you cover Post Hoc tests? What they are for and when to use them. Thanks

VERY VERY GOOD TUTORIALS. ABSOLUTELY AWESOME. THANK YOU VERY MUCH

Thank you this was simple and made it very easy for me to understand

Hi David! I value your videos. Thanks for making them. I would like to request a video about two-way MANCOVA. Thanks in advance.

Very instructive and easy to understand. Thank you !

Thanks for the Video, It's a great help.

I love your tutorials. I wish you could make a video for calculating Factorial ANOVA in R!

In SPSS, I think "Score" should be SCALE and "Age Group" should be NOMINAL. Other than that, this video is great! Thanks!

Love your style.

hi Sir, hi from India,,, thank you for the detailed video..it was really helpful to cover statistics portion for psychology optional in UPSC exam here.

Big THANK for from UAE ... Now I understand two way ANOVA with SPSS :))

Thank you for the information, one of my question solved,

Thank you very much for the incredibly nice and comprehensive explanation! it is very helpful.

It is very helpful. Thank you very much!!!

Thank you for sharing. All confusions clear. owe you man..!!!!

Lol this video was great and he's got a good sense of humor

Thank you sir, excellent video.

thank you for this!! thank you so so so much!!

Great job! Thank you!

Big THANK for you from UAE ... Now I understand two way ANOVA by using SPSS :))

Thank you very much, such a big help!

Great tutorial. Thanks alot

Appreciate that so much, you are the savior!

You make ANOVA very easy to me, thank you.

thank you so much i could cry this really helped

Hi Prof. How do we analyze if I have three independent variables (nominal) and one dependent variable (scale)?

thank you! u've made things a lot easier. :)

thank you for this tutorial!!!!!!!

thank you so much. I'm gaining confidence in stats now

Than You, sir! I am working on a model and performed two way anova as you described. I got dot (.) in place of p and f values. could you help me please?

thanks for this valuable information!

it was so simple and i learnt it easily

Muchas gracias! Algún día espero tener la narración en español también. Many thanks! Someday I hope to have the narration in Spanish too.

Great job, thank you

Hello Thanks a lot for your useful videos, you make statistics easy. my question is that, should the groups be the same size???

This is very good tutorial to understand ion simpleway

Brilliant exposition for students.

For my studies I have an assignment to write a report based on change blindness. I have 3 IVs and 1 dependent variable. Would this be the statistical data method to use? I'm really confused on how to work with SSPS. Thank you

THANK YOU VERY MUCH. I LOVE THE VEDIO.

Once again your video starts well, and certainly gives a clear explanation of how to calculate numbers. Please add more about what are the actual conclusions. As this is observational data, it is incorrect to say that either of these factors has a significant "effect" on score. That implies causation. What you really found was that there was a difference between the mean score for the boys and the mean score of the girls that was so large that it would be unlikely to occur if there really was no difference between these groups. So that leads us to reject the idea that the means are equal and say that the mean scores of boys are significantly different from the mean scores of girls. As we also found that at least one of the age groups has a mean score that is significantly different from the other age groups, we now need to examine some post hoc tests to see which groups are different. And then, even more importantly, we need to look at how large those differences are to see if they have any practical significance as well as statistical significance. We need more videos that develop statistical thinking, not just ability to calculate and blindly follow rejection rules. Thanks.

Hello! Thank you very much. Please how can i use this method for agronomic data? for example! Plant height and branching contribution to seed yield.

Thank you, Very useful

Many thanks!

Sir, just question is that subject the same as a factorial analysis under data reduction

Thanks! It is very helpful.

THANKYOU SO MUCH SIRR!!!

Thank you so much for the video!

VERY COMPREHENSIVE! THANK YOU VERY MUCH FOR SHARING YOUR KNOWLEDGE WITH US!

Well done...thank you!

Right... in Hypothesis testing it seems like you are doing the opposite thing. I just added a link to a playlist on Hypothesis testing (two short videos). You can find the link in this videos description.

Michael, sure I am. It is probably best you post your questions as a Facebook Message since you are not limited by space and you can add attachments too. There is a link to the MyBookSuck Facebook page in the video description).

Thank you!!! :)

confused right now as i am not a statistics person but will work on them and give verdict. Thanks for these need them exams nearer! Scary!

God bless!!! Thank you very much! I am so saved!

Is there a way to use a one-way ANCOVA with repeated measures? Ive looked everywhere and I cannot seem to find. I want to give a rational as to why one way ANOVA with repeated measures was used vs ANCOVA

Excellent sir

Ssss......love it! You help so much!

Great job :D

Yes I think a Two Way ANOVA sounds reasonable. If you want you can post a longer question on MyBookSucks FB page (see link in video description) and you can include an attachment with a message. I am curious what are your two independent factors and dependent variable. And when you write you have 11 variables do you mean observations?

It is easier than an expensive College tutorial. Gracias Amigo

How dose it work? null hypothesis is only a text. you can choose any text as H0. Please explain it. Thank you

Please, How can i use SPPS to make correlation and regression between the two mean of different treatment

Great!! Please also put for R/R Studio and SAS

Thank you sooo, sooooo much. Bless you!

Hi, Thank you very much for the tutorial. You made it easy to understand. I have a question here. If gender and age both cause difference, why the interaction of these two makes no difference? how does it happen? thank you in advance

In this case you used parametric data, but what i should do if i have non parametric data? What is the equivalent non parametric test for parametric 2 way anova?
