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.
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.
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!
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?
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).
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.
***** 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.
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.
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.
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.
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?
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.
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.
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.
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
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?
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
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?
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
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.
Easier is good! Thanks for the feedback. Make sure you like MyBookSucks on FaceBook (see link in video description). This will help others find the educational videos.
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
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? ruclips.net/video/6T6dvrwDe_U/видео.html
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
If the two factors do significantly influece students' scores, Why is there no interaction between these factors? Am I missing somthing about the defenition of "interaction" between factors?
Martha, I don't have the video (I should). I do have a video showing how to calculate a two way ANOVA by hand? Help it helps you. ruclips.net/video/lZFmFuZGQTk/видео.html
Thanks, I've already used that one. Hopefully I can try to use your other Excel templates to create my own. Thanks again! These vids are a massive help.
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?
Thank you for this video, it was very helpful.But you did not explain the use post hoc (tukey test) I have exam on Tuesday, can you please post one more video explaining the post hoc tukey test and its interpretations in two way ANOVA Thankyou.
Hi StFun, I hope you are well. Could you plz help me? I have two dependent factors (Healthy and infection) and three independent factors( Size,Height, diameter) do you think two way ANOVA is the best to go? please How can I contact with you Regards
I am not asking in the relation to above problem (How to Calculate a Two Way ANOVA using SPSS) I wish to know wt sh'd we do if thr is any missing observation happen to occur in an experiment (data)..... then hw necessary way we have to follow for analysis/ Plz let me know ASAP.....
If anyone is here 11 years later, for interpreting output in SPSS for factorial ANOVA, we would not have to calculate F crit to determine significance, correct? We would just look at the P-values? Also, are "gender" and "age_group" considered main effects while "Gender * Age_Group" is considered an Interaction?

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

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!
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!
Thank you for the time and effort you put in. It really shows in the high quality and concision of your videos.
You are a life saver!
The amount of work you dedicate to each video is admirable! Thanks to your videos, ANOVAs are MUCH easier to understand!
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!

Muchas gracias! Algún día espero tener la narración en español también.
Many thanks! Someday I hope to have the narration in Spanish too.
No explanation is greater than this. I have already shared! Thanks..
You explain slowly and clearly.. I appreciate your understanding..
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.
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
Excellent explanation and I really appreciate for making such kind of video.
Thank you for posting these videos. They were very helpful. You have great sound on these videos and the pace was perfect. Many thanks!

Big THANK for from UAE ... Now I understand two way ANOVA with SPSS :))
Big THANK for you from UAE ... Now I understand two way ANOVA by using SPSS :))
Thank you. You make this sound easy. Your narratives help make sense of all this.
thank you so much for the best explanation of 2-way ANOVA!
I am currently completing my dissertation and could use your expertise. Are you available for dialog? Mike
It is easier than an expensive College tutorial. Gracias Amigo
true to the YT name, you are making this fun!
You make ANOVA very easy to me, thank you.
Somilas GH You are very welcome!
Fantastic video, best one I've found so far. Really gonna help with my thesis!!!

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

Many thanks!
May I know if some observations are missing then in variable view.....? hw to go for analysis ? Plz let me know ASAP.....
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.
Dear, very good explanation,👍 when do we use post hoc ??
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
Than You, sir!

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!
Thank you this was simple and made it very easy for me to understand
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?
Do you have a video on how to do a write up for this?
concise and explained simply... great job
Sir, just question is that subject the same as a factorial analysis under data reduction
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
Excellent!! but can you please tell me what are the maximum marks in score?
This was so clear and easy. THANK YOU!!! It makes so much sense now.
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.
Hello
Thanks a lot for your useful videos, you make statistics easy.
my question is that, should the groups be the same size???
Easier is good! Thanks for the feedback. Make sure you like MyBookSucks on FaceBook (see link in video description). This will help others find the educational videos.

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.
can i use two way anovq to analyze a proximate analytical result?
Thank you so much for the series provided, It is really easy to follow and absolutely helpful.
Lol this video was great and he's got a good sense of humor

cheers mr statistics fun :)
Thank you. It is a great video. I like the way you explain the main points.
You can do it!
it was so simple and i learnt it easily
VERY VERY GOOD TUTORIALS. ABSOLUTELY AWESOME. THANK YOU VERY MUCH
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 Prof. How do we analyze if I have three independent variables (nominal) and one dependent variable (scale)?
Incredibly clear and helpful, thank you for making this video!
thank you so much. I'm gaining confidence in stats now
Very instructive and easy to understand. Thank you !
If the two factors do significantly influece students' scores, Why is there no interaction between these factors?
Am I missing somthing about the defenition of "interaction" between factors?
Your vids are great! Really helping. But is there one for putting a two-way ANOVA into Excel, like with the one-way ANOVA?

absolute legend, this video helps so much. Thankyou !!
Thank you for this video, it was very helpful.But you did not explain the use post hoc (tukey test)
I have exam on Tuesday, can you please post one more video explaining the post hoc tukey test and its interpretations in two way ANOVA
Thankyou.
Great!! Please also put for R/R Studio and SAS
Thanks for the Video, It's a great help.
Hi David!
I value your videos. Thanks for making them.
I would like to request a video about two-way MANCOVA.
Thanks in advance.
Hi StFun,
I hope you are well. Could you plz help me? I have two dependent factors (Healthy and infection) and three independent factors( Size,Height, diameter) do you think two way ANOVA is the best to go? please How can I contact with you Regards
what should i do if the f value and sig value do not appear?
I love your tutorials. I wish you could make a video for calculating Factorial ANOVA in R!
Can I please ask, how is it possible for the combination of Gender & Age to have no effect, when, individually, they have an effect?
I am not asking in the relation to above problem (How to Calculate a Two Way ANOVA using SPSS) I wish to know wt sh'd we do if thr is any missing observation happen to occur in an experiment (data)..... then hw necessary way we have to follow for analysis/ Plz let me know ASAP.....
what shoud it be done with the F column?

thank you so much i could cry this really helped
thank you for the series! :) helps a lot to understand
If anyone is here 11 years later, for interpreting output in SPSS for factorial ANOVA, we would not have to calculate F crit to determine significance, correct? We would just look at the P-values?
