We need an address to send thank you cards. Seriously now, this is SO helpful!

Excellent teaching! Your clips save my life in studying SPSS/Statistics!

Dr. Grande- This video highlighted how to use simply. This topic was easy to understand and I find that SPSS is easier to use than Excel. The information that you provided made it easier to understand they study.

absolutely love you... your tube is clear and concise.. You don't waffle but simply stay on the topic. thank!

Thank you for your videos. I needed a clearer explanation than the one my professor, who does not speak clear English, could provide. Your video is clear, concise, and you do not rush through. The explanations you give at each step relieve all sorts of frustration I have been having with this class. Thank you a ton!

This was a very clear video that helped me to understand how I would conduct a two-way ANOVA if I were to actually conduct my study. I am beginning to understand SPSS a little more from watching these videos.

Your statistics videos are saving my life

Significantly helpful video and I can't thank you enough.

Thank you so much. Your students must be happy to have you as a teacher.

Very helpful information on conducting and interpreting results from a factorial ANOVA!

This was another great example of the differences of when to use the ANOVA instead of the t-test. I understand the interaction effect much more clearly. The SPSS is a clear representation of the data which makes it easy to understand once the data is entered correctly. It still may take me some time to learn the various data entry tabs with SPSS.

Wonderfully explained, and thorough with clean examples and rhetoric. Thank you!

thank you sooo much! this was very clear and saved me much frustration.

Omg this is so amazing!!!! Literally doing this right now for school. Can't believe you do this as well!!!!!! I mean video wise!!!!!!

Great video like always! You always save me with your videos 😁

Great vidoe that clearly explains how to conduct a Two-Way ANOVA in SPSS. I really loved how easy this video was to follow. It was a good reminder of two-way ANOVA's for me as well.

Thank you Todd. Happy new year to you and your closest.

Thank you!!! You help me a lot to understand statistics and SPSS

This is the video I needed! thank you!! Awesome explanation!

Thank you so much for this great video, it really helped us!! :D

thank you a lot. It was very very helpful. you are a wonderful teacher.

Thanks for the video, it was helpful. It is actually optional lecture for an online statistics class at ASU.

Very detailed and helpful. Thanks for sharing

Wow thank you so much for this video, it explained things that I should know that I didnt even know I should know

I have just finished an exam and I cannot thank you enough for the amount of help you have been with your videos. God bless you

As always, very helpful

This is wonderful. Thank you.

Excellently explained Thanks a lot

Two way ANOVA- good explanation why not to use multiple T-tests. A little fuzzy on which Post Hoc tests to run but will probably be explained in further videos. Nice review of how to interpret the graph.

You just saved my undeserving life, thankyou sir 🙏🏼🙏🏼

great tutorials, thank you for sharing

thank you! with love from malaysia

This helps when working with more than one IV but I'm still a bit confused on the homogeneity of variance, which seems to have been glazed over in this video.

Running multiple T tests with more than two levels in the IV and more than one IV will increase Type 1 error; ANOVA is better because it can study the interaction effects. Thanks for the foregrounding.

thank you for the video but please turn up the volume

The graphs were helpful as I am a visual learner. I understand when to use the Two-way ANOVA, just not certain about the post-hoc tests and outliers in the data.

Hello Dr. Todd, Thank you for this video! I don't know if you still look at the comments but I have a question regarding the two-way ANOVA. One of my variable (Distraction) is significant while Group (2 levels) is not. Their interaction is significant. The SPSS is not showing the post-Hoc test for the interaction effect but only for the main effect. Is there a way to calculate post-hoc test for the interaction terms?

Thank you for this video Dr. Grande. If you don't mind me asking...what Post hoc test does one use when the sample sizes are not similar? Please and thank you

Thanks for this video

Seeing all the data in the tables and in different comparison is very helpful, then, seeing it all together in the graph was great. This was quite easy to follow. Like some others, I don't fully understand the Post-Hoc and REGWQ, what did that show?

really good video.

Thank you. no need to do multiple comparison for interaction effect?

Thank you!

Thank you so much for this video! What can I do if my dependant variable is skewed/doesn't follow a normal distribution?

Hello Dr. I did not get that blue red green circle for my independent variable. How?

This video was so helpful. Thank you!

Hi! Thanks for this great video. I have a question in regards to the post hoc tests. The differences in between duration refer to both genders? In other words the differences between 6 week and 18 week is refering to what? males females or both?

really helpful thanks😍😍😍🥰🥰🥰👍👍👍👍👍👍

Hello!! Your video is so helpful but do you know what should I do if I got a results said “ All absolute deviations are constant within each cell. Levene F statistics cannot be computed” ?

I am not sure which Post-Hoc test to use. What does R-E-G-W-Q mean? I liked the combined marginal means of symptom level graph, I am a visual learner so it is easier to read than some of the tables.

HELP PLEASE... My 'tests of between subjects effects' box has a full stop where the mean square, F, and Sig figures should be for my main effects and interaction

For postdoc, which test to be used if sample size is not same?

Thank you.

what should be the post hoc and confidence interval adjustment for unequal sample size

can this be used to analyse a 2x2 ANOVA within and a 2x2 ANOVA between participants?

Thank you for the video, doctor. I wonder if we have repeated data and replication data simultaneously, how can we do factorial design(ANOVA) by SPSS. What I mean is: For 10 samples , 5 Male, 5 Female. sample 1, we do treatment 1, treatment 2, treatment 3, sample 2, we do treatment 1, treatment 2, treatment 3, ....... sample 10, we do treatment 1, treatment 2, treatment 3. this will produce 3 repeated data for each sample. So gender can be between subject factor, and treatment be the within subject factor. But if we do 3 replications(maybe random simulation results) for each repeated data. Which means for sample 1(as well as for sample 2~10), 3 replications for treatment 1,3 replications for treatment 2, 3 replications for treatment 3. How can I form the table and do factor factorial design(factorial anova) for this situation? Please help me.

How do you do anaova when there is over 5 independent variables in the analysis?

Thank you for your video its extremely helpful! Can I ask please why on the 12:28 - table 4. Duration * Gender there is no significance column? How can I examine significance of both occurrence?

If I have 3 independent variable, can I still use two way anova?

what version of SPSS did you used ?

This would work in a 2 x2 data ( for examples, 2 sexes and 2 diets and one dependent variable)?

How do you write your results in APA style. I need help with that part.

thanks a lot

You have outliers in your data means sample wasn't drawn from a normally distributed population, means not suitable for anova. Is it correct?

Whenever I click options in the univariate dialog box, it doesn't give me the option to add any factors to the factor interactions box... as in it doesn't even contain that portion of the dialog box at all, just the display/heteroskedasticity tests/parameter est. w/robust standard errors options?? Do I need to do something to my variables prior to running this test? (reference 6:06 in video I believe the box I'm missing is "Estimated Marginal Means"?) P.S. Love your videos!

5:13 Hello Dr Todd What do I do when working with two independent variables that have just two groups each, when I obviously cannot perform a post hoc test? Thank you for this lecture❤, it's really helpful

Dr. Grande, hi. When time, please explain the following regarding homoscedasticity. "The problem with having different amounts of variability in the groups rests in the fact that the within-group variability is used as the error term for the F-ratio. If the groups differ in their within-group variability, then it doesn't make sense to use this as the error term for the F-ratio and the logic of the F-ratio (between-within) comparison falls apart. Thus, we turn to different analytical approaches when this happens."

thank u.......

A two-way ANOVA seems a little more difficult for me to grasp. The post hoc tests and pairwise comparisons were new to me and left my mind a little hazy.

Great!

May we know sir, what version of SPSS you're using?

Hallo. I have followed your example but i dont get any F-values. Any clues?

Can I use only one factor at fixed factors?

how can u make it one tailed?

Are you sure Two-Way ANOVA is robust enough to neglect the effect of homogeneity of variances?

i thought you cannot have a sig of 1 or 0 ...so it would always be a number in between, so how come week 6 vs week 12 has a sign of 1???

How to put superscript? Please.

Everything is good with ur demonstration, the only thing lacking is your voice is not audible.

what is the difference between LSD and Benferroni?

Why does my f value and p value just show dots?

What are the steps in spss to graphing a two-way anova?

Tanks for your videos. Could you please show me how to do Multiple Classification Analysis using SPSS synthetic? Tnks

I liked the estimated marginal of means graph. It shows the data in a linear line of gender so we can see how the two are different. Two way Anova is becoming clear as to variables and levels.

thx todd nic very nice

starts at 4:10

I see how this system differs from Excel, though they look similar. I would like the chance to compare the two with a study. It would be nice if we could get an in-class demonstration of both and compare and contrast the two as a group.

What is psych bike in SPSS

Where can i get SPSS ??

video good but the volume needs in an environment that is completely silent to hear the voice.

Awesome explanation, but the video isn't showing clearly

What if normality is violated and transforming doesn’t fix this? What is the non-parametric model?

Hello Dr. Your Video explanation on two ways anova in spss is very clear and useful for me. I am studying on Agricultural science, so statistics analysis is focused on agricultural research. Therefore, could you give me model of explanation base on agri research statistics pls.?

It would be great if next time you could also attach the data file you used in the example. Great video though.

i got error zero in annova test
