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.
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!
No there are no missing observations. In variable view the rows equate to columns in the data view. In this case I have three columns (Gender, Score, Age_Group) in the data view and I have 18 observations.
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?
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).
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.
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!!!
Talking Pen Thanks for your kind words. The number of people that are not into statistics greatly out numbers those that are into statistics. Good luck in your classes. Hopefully you will like, share, subscribe, If you get a chance could you please like our FB page. www.FaceBook.Com/PartyMoreStudyLess It will help others find the videos.
***** You are very welcome Jennifer. I appreciate it that you took the time to let me know my videos are helpful. If you get a chance like, share the videos (and www.Facebook.Com/PartyMoreStudyLess). This will help others find the videos. Good luck in your studies too.
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.
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
James, SPSS will generate the exact p value for you. As long as the p value is less than your confidence level (p < .01 or 99%, p < .05 or 95%), you should be good to go.
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.
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?
Sure I can help, tell me more about the problem you are trying to solve. It may be easier for you to post a message on MyBookSucks on FaceBook (see link in video description). Your comment can be longer and you can add an attachment.
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
thanks for nice tutorial, I just wonder why the score, as dependent variable, is registered as categorical nominal, while it is continuous; and in independent variables, which suppose to be both categorical, the age-GROUP is registered as continuous. Does it affect the analysis in the SPSS?
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
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?
Thanks ,good video. Can I ask whats the difference between using a Univariate analysis of variance and a repeated measures in SPSS ? are they the same thing ?
Ian Dunican I included a link to a video on SPSS Repeated Measures (not mine but it should help you) Univariate is using just one variable (uni, as in uni cycle). This is frequency diagrams, calculating the mean, or standard deviation. Imagine tracking Math Anxiety. I could calculate Math Anxiety at one point in time. Repeated measures allows you to track a variable over more than two time frames. I could measure math anxiety, then have people watch some of my videos and measure them again, I could do this several times (repeated measure). Repeated Measure is just that. I am tracking the same variable over multiple time frames. Make sense? th-cam.com/video/6T6dvrwDe_U/w-d-xo.html
Thanks so much for the very informative videos. MY BOOK SUCKS also. You helped me understand the two way ANOVA. I just may get a passing grade on the next quiz.
I have 12 teachers rating 3 student speaking performances. I want see if teachers' scoring is affected by their demographic background (collected via questionnaire), student gender and language background. How should I set up the data in SPSS? Two-way ANOVA can help? or Regression?
Hi, I particularly liked the animations you have used. Could you please share the tools you use for creating educational tutorial. Being a tutor myself, I am most interested to know. Best wishes
I think an interaction is more than simply the additive effect of each IV on their own. It has to be an effect that is more than what is explained by looking at the effects of the IV's independently.
you amazing. thank u very much for ur explanation. but i have question for u, my experiment was measurement bacterial adhesion with antibiotic and without antibiotic, each one with three replicates. so, what i must use? one way anova ot t-test. please help me I'm M.Sc. student in Microbiology.
hello, I hope you'll find time to reply my question. I'm planning to do two-way anova for my paper i have two independent factors with 11 variables (all nominal) and one dependent variable-- is two way anova the best way to go? thanks.
sir, please reply, when you say fail to reject null hypothesis, it means we are accepting alternate hypothesis?? or some other interpretation it can have??? waiting for your reply. thanks for all your uploads.
We have a hypothesis which is "gender will affect the score" This is our hypothesis. Now scientists don't try to prove their hypothesis but disprove it (to see how strong it is) and therefore there is always a null hypothesis. A null hypothesis is the exact opposite of our hypothesis, in this case "gender will have no effect in scores". If our results are statistically significant then that means that our hypothesis is correct and that the null hypothesis (which is there to disprove our point) is rejected.
This tutorial series on the two-way AONVA, including SPSS, is a LIFE saver. Very well done!

Thank you for the time and effort you put in. It really shows in the high quality and concision of your videos.
The amount of work you dedicate to each video is admirable! Thanks to your videos, ANOVAs are MUCH easier to understand!
Thanks for explaining it so well..I could not find a better video on youtube explaining how to perform ANOVA test in SPSS
the best tutorial i've seen till now!!! Been looking for months! Thank you!
You are a life saver!
This is a good youtube, simple and easy to understand. Thank you!. Have a nice weekends!

Your videos are brilliant, I was completely lost until I watched this!
Muchas gracias! Algún día espero tener la narración en español también.
Many thanks! Someday I hope to have the narration in Spanish too.

In SPSS, I think "Score" should be SCALE and "Age Group" should be NOMINAL. Other than that, this video is great! Thanks!
Score is ratio , age also scale , gender nominal
Big THANK for from UAE ... Now I understand two way ANOVA with SPSS :))
thank you so much for the best explanation of 2-way ANOVA!
Big THANK for you from UAE ... Now I understand two way ANOVA by using SPSS :))

Thank you so much for the series provided, It is really easy to follow and absolutely helpful.
you are a lifesaver ! Thanks so much for simplifying stuff down.
true to the YT name, you are making this fun!

+David Jahanlu The most important thing is to make sure you have all your variables classified correctly. SPSS takes care of the rest of it for you.
Great. Really clear. Do you cover Post Hoc tests? What they are for and when to use them. Thanks
Incredibly clear and helpful, thank you for making this video!
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.
Great videos sir, best I have seen . Thank you
This was so clear and easy. THANK YOU!!! It makes so much sense now.
Thank you. It is a great video. I like the way you explain the main points.
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!
concise and explained simply... great job
Sir, just question is that subject the same as a factorial analysis under data reduction
Thank you this was simple and made it very easy for me to understand
Thank you very much for the incredibly nice and comprehensive explanation! it is very helpful.
+Baktash Mohammadi You are very welcome. Hopefully you will get a chance to like and share the videos. This will help other students find them.
Hi Prof. How do we analyze if I have three independent variables (nominal) and one dependent variable (scale)?
It is easier than an expensive College tutorial. Gracias Amigo
VERY VERY GOOD TUTORIALS. ABSOLUTELY AWESOME. THANK YOU VERY MUCH
Hi David!
I value your videos. Thanks for making them.
I would like to request a video about two-way MANCOVA.
Thanks in advance.
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
absolute legend, this video helps so much. Thankyou !!
I love your tutorials. I wish you could make a video for calculating Factorial ANOVA in R!
Dear, very good explanation,👍 when do we use post hoc ??
Very instructive and easy to understand. Thank you !
I am currently completing my dissertation and could use your expertise. Are you available for dialog? Mike
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
Hello
Thanks a lot for your useful videos, you make statistics easy.
my question is that, should the groups be the same size???
This was a great video. Thank you for being so thorough.
thank you for the series! :) helps a lot to understand
Do you have a video on how to do a write up for this?
You can do it!
Thanks for the Video, It's a great help.
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?
May I know if some observations are missing then in variable view.....? hw to go for analysis ? Plz let me know ASAP.....
Great!! Please also put for R/R Studio and SAS
Thanks ,good video. Can I ask whats the difference between using a Univariate analysis of variance and a repeated measures in SPSS ? are they the same thing ?

Love your style.
It is very helpful. Thank you very much!!!
Good observation.
Please, How can i use SPPS to make correlation and regression between the two mean of different treatment
How dose it work? null hypothesis is only a text. you can choose any text as H0.
Please explain it. Thank you

I think an interaction is more than simply the additive effect of each IV on their own. It has to be an effect that is more than what is explained by looking at the effects of the IV's independently.
can i use two way anovq to analyze a proximate analytical result?
How I can account the Total and Corrected Total?
Thank you
Lol this video was great and he's got a good sense of humor
This is very good tutorial to understand ion simpleway
you amazing.
thank u very much for ur explanation.
but i have question for u,
my experiment was measurement bacterial adhesion with antibiotic and without antibiotic, each one with three replicates. so, what i must use? one way anova ot t-test.
please help me I'm M.Sc. student in Microbiology.
hello, I hope you'll find time to reply my question. I'm planning to do two-way anova for my paper i have two independent factors with 11 variables (all nominal) and one dependent variable-- is two way anova the best way to go? thanks.
it was so simple and i learnt it easily
Can I please ask, how is it possible for the combination of Gender & Age to have no effect, when, individually, they have an effect?
Thank you sir, excellent video.
what shoud it be done with the F column?
what should i do if the f value and sig value do not appear?
Ssss......love it! You help so much!
Susan King Also nice to hear Susan that my videos are helpful.

Ah shit I just saw this comment was a year ago
What's dat width column in variable view??
