Dang! That is wonderful to hear that you think my work is a masterpiece. I really appreciate that because I do put a lot of time and energy into my videos.
Thank you so much for this, you've saved my life (and my grades). This is genuinely such a simple concept to grasp when explained like this - I wish all of my math teachers and lecturers had explained the logic behind these concepts like you do because I would have fallen in love with mathematics sooner.
Saying your own work product is a “masterpiece” seemingly apropos of nothing (at least post it as a reply to a viewer comment) is going to make you appear a lot more arrogant than you probably are. It’s a cheap “social proof” advertising technique
Seriously! I'm taking second year stats for psychology and our uni brought in a PhD candidate guest lecturer for this concept (literally the most complicated part of the course) who took a whole hour to explain what this video did in 10 minutes 🤦♀️
WOW, spot on man. So far your videos have been the cleanest, and most presentable for easy visual learning, and your explanations the most straightforward, practical, and logically applicable! Truly beautiful. You have a gift, don't stop, please!
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.
Thanks a lot for this. I'm a visual guy, and this really helps sort it out for me. As a college senior (age 62) I can use all the help I can get. Thanks again!
Seven years have gone by and this is still the best video out there for two-way ANOVA. Prove me wrong I'll wait (As in, this video is awesome... but if you can prove me wrong I'd appreciate it. There are some really impressive videos out there for linear algebra, calculus, etc that this doesn't quite compare to)
You are deadset incredible. Our entire class is struggling with our lecturer who makes a lot of errors and is not good at explaining concepts. We have completely been reliant on you and are all planning to include this in our unit feedback so that the university may have a look and see what is expected of succinct teaching. Thank you thank you thank you
You are amazing, please don't ever stop making these videos. You're helping so many of us undergrads finally understand stats, when our lecturers suck! Keep it up!
this was amazing. i hated stats because the profs and teachers keep using big words and throw this ratio that ratio and whatnot right at the beginning. with your example and very clear presentation, i was able to understand the concept behind ANOVA perfectly, within minutes!
It is very clear and step by step explanation of two way ANOVA. Glad that I got to see this video for better understanding. Thanks for this video and I appreciate your work!
It's a great introduction, It's been about 4 years since I last used two-way ANOVA and needed a quick reminder. I remember covering at Mach 7 during my course using algebra so I liked your gentle pace. The only suggestion I have for improvement is to provide better explanation of the concept of interaction otherwise great!
May God fk my uni teacher for getting paid and not being able to teach me a quarter of this single video offers. You are a champion, well-put-together video. Proficiency at its best
oh wow!!!! I know I'm going to do much better in my stats class now that I have found your videos. Thank you so much for explaining this so clearly and, your visuals are great.
Great video format, elegantly designed, and easy to follow, you don't put to much information and everything is neatly organized. Great content, keep up the good work!
Well thank you for that! It is much appreciated. Make sure you like MyBookSucks on FaceBook (see link in video description). This will help others find the educational videos.
You are very welcome Jakob. Make sure you like MyBookSucks on FaceBook (see link in video description). This will help others find the educational videos.
I appreciate you thanking me. Make sure you like MyBookSucks on Facebook (see video description for link). This will help others find the educational videos.
You are very welcome too. Make sure you like MyBookSucks on FaceBook (see link in video description). This will help others find the educational videos. I was going to call my company MyProfessorSucks but went with MyBookSucks instead :)
That would be great. I would really appreciate that and other students would appreciate that as well. It may be easier for you to send a message on facebook since you can't have an attachment on RUclips. You can find a link the the MyBookSucks FaceBook page in the video description of this video. Thanks again!
I'm probably about to fail my DOE course but I learned a lot. It sucks to have to take it again. This is not a good course to learn without a good teacher.
Great video. Lets say I have 2 treatments (factor 1 with two levels) and I have a control group that gets no treatment. I have pre and post-test for all three groups. What test is that? The test-scores are numerical.
Hi! If I am planning to compare the effect of two independent variable (say: type of sweetener and daily intake frequency) on one dependent variable (antioxidant capacity), do I still need to have a negative control group? Thank you so much!
Can I do 2 way Anova with 5 categories for each? So if I had red, blue, pink, white, brown flowers in garden 1, 2, 3, 4, and 5. I want to compare, for example, measurements of the flowers. I want to see if location or type of flower- or both- has the biggest effect. But every 2 way anova I see, one of the categories only has 2 options (like girls and boys)- implying that more is too much.
Hello. Please I want to ask you a question. If we have one independent variable and we want to test its effect on two dependent variables, what statistical analysis system we'll use. Thanks in advance.
I've watched all the videos on ANOVA one way, but somehow I am still confuse how does the ultimate result (reject/fail to reject) relates to the null hypothesis. What is the initial null hypothesis for the one-way anova example (level of stress)? thanks, you made things a lot simpler
I had a question, are you using a fixed effects model (model 1) or a random effects model (model 2). Whichever you chose, can you please explain the reason behind your choice? Thanks in advance!
That is the goal Ricardo... now you have time to party or do something you would rather be doing that statistics. As our tag reads, "Party More Study Less"
this looks a lot like OLS. What is ANOVA for that you can’t do with standard econometric methods? I always thought that ANOVA was some really advanced concept in inferential statistics, but it looks very similar to the linear regression methods I'm familiar with
What happens if my groups have different participant sizes. I want to do factorial analysis based on age group and job banding but I have more participants in certain age groups in comparison to others. Can I still do the above analysis?
Hi! do you maybe have any videos of how to do Ancova test? I tried to search but it seems there are no from you-and you are really great at explaining so it would be great to have one!best regards
I just want to know an important thing regarding Nested and two away ANOVA with replication. If I use two away ANOVA with replication on nested design is that wrong? Note that I get the same answer as nested by ANOVA
Thanks for the lesson professor ! But i have some quetions, in pratical therms, whats defines the statistical test its my hypothesis and my experimental design ? Using your example, if i am interrested in analyse the effects of gender and age over scores, i need to collect the data for scores, gender and age all for the same sample from a population, and at end use Two-way ANOVA. But, what happen if i have the same hypothesis and collect two individual samples, 18 people for age (6 people per age group) and 18 for gender (9 per gender group)? In this case, i need to use One-way ANOVA for the first case and t-test for the second? In this analysis i am creating bias because of a poor design ?
Dang! That is wonderful to hear that you think my work is a masterpiece. I really appreciate that because I do put a lot of time and energy into my videos.
do you have a series on anova and modeling/testing in r studio
what makes it a masteriece is that after each essential sentence or statement you take a second thus giving an audience time to understand
Thank you so much for this, you've saved my life (and my grades). This is genuinely such a simple concept to grasp when explained like this - I wish all of my math teachers and lecturers had explained the logic behind these concepts like you do because I would have fallen in love with mathematics sooner.

No one has been this good at teaching ANOVA literally
Seriously! I'm taking second year stats for psychology and our uni brought in a PhD candidate guest lecturer for this concept (literally the most complicated part of the course) who took a whole hour to explain what this video did in 10 minutes 🤦♀️
You mean apart from at least a half dozen other RUclips videos? Literally.
WOW, spot on man. So far your videos have been the cleanest, and most presentable for easy visual learning, and your explanations the most straightforward, practical, and logically applicable! Truly beautiful. You have a gift, don't stop, please!

N.B. who said it " a blessed mind is too busy for good." Dear Prof. STAY Blessed.
"1 minute of video takes about 12 hours".....U R exceptional!!!
Generations all over the world benefit from your incredible content. Thank you a lot
You are the best!
that's not very efficient ngl
We appreciate your time, effort and dedication. Also, your explanations are saving grades. Thanks.
One of the most straight forward and most structured tutorials I have seen so far! Keep on!
Thanks a lot for this. I'm a visual guy, and this really helps sort it out for me. As a college senior (age 62) I can use all the help I can get. Thanks again!
College senior here at 45 yo! *waves*

simple to complex is everyone should seek for, your lectures are perfect for any novice
Exceptionally well put together video, second time watching and just realising how much it covers while looking simple
I have this class at 10am!! Thank you for the great explaination, this helped me to understand One_way ANOVA also!
what a way to teach, you got amazing teaching skills, and what a cleanest way to demonstrate, I loved it
Thank you Professor David!!! you help me building confidence in statistics and my research quality! Thank you for all the videos! you are the best!
Thank you Professor David! Your video has definitely made the concept easier to understand.
May God fk my uni teacher for getting paid and not being able to teach me a quarter of this single video offers.
You are a champion, well-put-together video. Proficiency at its best
Your lecture is really clear and good to understand for me who don't have the experience in statistical analysis. Thanks a lot Sir.
oh wow!!!! I know I'm going to do much better in my stats class now that I have found your videos. Thank you so much for explaining this so clearly and, your visuals are great.
Great video format, elegantly designed, and easy to follow, you don't put to much information and everything is neatly organized. Great content, keep up the good work!
Thank you for making this so clear! Your voice sounds really calming too :)
Super Helpful!!! I just read a whole chapter in a textbook and after watching this 8 minute video, all is clear!
Amazing video... like literally the best explanation of this I’ve seen in my years of math 👍🏾
For the first time I feel like I'm beginning to understand statistics!!!! Thank you!!!
Very nice visualization! Props! Also the explanation were very easy to understand, I wish there were more content like this in general.
Well thank you for that! It is much appreciated.

Thank you! you don't know how this was helpful in my work, and hoping to see more case studies.
Thank you so much...you made ANOVA too easy to understand ..Thank you again
I appreciate you thanking me. Make sure you like MyBookSucks on Facebook (see video description for link). This will help others find the educational videos.
This gives me a very good understanding of the topic. Very clear
Very helpful. Keep it up. Clarifying a lot my professors like to speed through.
thanks, after watching your videos , theory becomes much more easier to understand :)
Beautifully made video & simplified explanation.
thank you very much...this is very clear and helpful.. now at least i know how to proceed with my analysis..
Best explanation ive seen so far!
This actually saved me. I am already losing hope understanding this topic. Kudos!
Thank you so much. I wouldn't be passing stats without you.
I love your video. Thank you a lot, for this video helps me in my statistics. I was scared but with this video I will conquer it with confidence :D
Very interesting lecture through visualization methods

Thanks again!
This is amazing and very helpful...You have made it much clear....
I was wondering wether this two-way ANOVA is the same as a Factorial ANOVA and if so, how to report this step by step. Thank you for all your help!
Thank you very much!

So EASY TO UNDERSTAAAAND! thank you very much for explaining it
Fabulous explanation!! Many thanks!
Brian.. I am not sure what you mean by 2^k designs?
Appreciated you efforts dear 🎉
great explanation...i never seen clarity like this
I made an A on this section of my stats class! Thank u!
I'm probably about to fail my DOE course but I learned a lot. It sucks to have to take it again. This is not a good course to learn without a good teacher.
Thank you for making this and the other videos on Two Way ANOVA
SUPERB AND SIMPLE EXPLANATION THANKS A LOT SIR
Great video. Lets say I have 2 treatments (factor 1 with two levels) and I have a control group that gets no treatment. I have pre and post-test for all three groups. What test is that? The test-scores are numerical.
this was just too helpful to be true, thank you!
You are an amazing tutor. Thanks 👍
Excellent presentation/explanation!
Thank you so much for making and sharing this.
Hi! If I am planning to compare the effect of two independent variable (say: type of sweetener and daily intake frequency) on one dependent variable (antioxidant capacity), do I still need to have a negative control group? Thank you so much!
Thank you sir for the knowledge you gave.
You're the best! Thanks for the clear teaching!
You are very welcome!
what is meant by multiple comparison ? does it has any relation with correlation , or ANOVA ? thank you !
Can I do 2 way Anova with 5 categories for each? So if I had red, blue, pink, white, brown flowers in garden 1, 2, 3, 4, and 5. I want to compare, for example, measurements of the flowers. I want to see if location or type of flower- or both- has the biggest effect. But every 2 way anova I see, one of the categories only has 2 options (like girls and boys)- implying that more is too much.
You are awesome, I was so confused before. Thank you for simplifying.
Thanks a lot for this video! Really helped me with my stats class.
you are a magician sir
Excellent work ... Thank you for your time and effort
This is just incredible work. My goodness.....
you sir have done the world a good deed
Thank you for your clear and great explanation!
Hello. Please I want to ask you a question. If we have one independent variable and we want to test its effect on two dependent variables, what statistical analysis system we'll use. Thanks in advance.
You are absolutely fantastic !!!!!!!!!!!!!
You are awesome, you explain it very clearly!
thanks a lot sir. this really helps me on my stat report.
This is the simplest way to understand ANOVA. Thank you so much @statisticsfun
Thank you SOOOOOO much!!! You truly have a gift (contrary to my professor).
I've watched all the videos on ANOVA one way, but somehow I am still confuse how does the ultimate result (reject/fail to reject) relates to the null hypothesis. What is the initial null hypothesis for the one-way anova example (level of stress)? thanks, you made things a lot simpler

That is the goal Ricardo... now you have time to party or do something you would rather be doing that statistics. As our tag reads, "Party More Study Less"
beautifully simple and clear and i love it
this looks a lot like OLS. What is ANOVA for that you can’t do with standard econometric methods? I always thought that ANOVA was some really advanced concept in inferential statistics, but it looks very similar to the linear regression methods I'm familiar with
Couldnt thank you enough for these excellent videos.
What happens if my groups have different participant sizes. I want to do factorial analysis based on age group and job banding but I have more participants in certain age groups in comparison to others. Can I still do the above analysis?
Hi! do you maybe have any videos of how to do Ancova test? I tried to search but it seems there are no from you-and you are really great at explaining so it would be great to have one!best regards
How do you do anova when there is 9 independent variables and 1 dependent variable in the analysis?
Great video! is there a typo in the F-ratio? 0.69 (instead of 0.62).
I just want to know an important thing regarding Nested and two away ANOVA with replication. If I use two away ANOVA with replication on nested design is that wrong? Note that I get the same answer as nested by ANOVA
Best Mathod of one way and two ways slab.
Really great video. Well explained!!!
Thanks for the lesson professor !
But i have some quetions, in pratical therms, whats defines the statistical test its my hypothesis and my experimental design ?
Using your example, if i am interrested in analyse the effects of gender and age over scores, i need to collect the data for scores, gender and age all for the same sample from a population, and at end use Two-way ANOVA.
