Analysis of Covariance (ANCOVA) - SPSS (part 7)

I demonstrate how to perform an analysis of covariance (ANCOVA) in SPSS. The first part of the series is relevant to the ANCOVA tested through the conventional approach to doing so by getting SPSS to estimate adjusted means through the GLM univariate utility. In the second part of the series, I demonstrate the exact correspondence between ANCOVA and multiple regression.
NB: The results of the analysis in this series found that males appear to have larger cranial capacities than females, even after controlling for the effects of body size. However, it should be important to emphasize that research has found that there are little to no general mean differences in IQ between males and females. Furthermore, there is neuroanatomical research to suggest that female brains appear to have more neurons per cubic cm than male brains. Thus, the difference in cranial capacity/brain size between the sexes may be counteracted by the differences in neuronal density.

You sir, are my hero!
Thank you so much for this! I've spent hours in class trying to figure this stuff out, and this 40min guide was ten times as useful!

[@Chandrajith100]

This video saves class work of close to 3 weeks in this set of videos!!! Thanks a lot!!!

[@RH91750]

I've watched all 7 videos and feel a deep need to THANK YOU for helping me to understand ANCOVAs, as well as how to run one in SPSS. You have made my homework assignment this week so much more interesting and doable!

[@ashwaniiop]

Excellent demonstration of the ANCOVA. The simplicity with which the results were the interpreted and almost same deduction with two methodological approaches for scaled dependent variable with categorical and scaled independent variable is deeply appreciated. Would line to have more of such videos on Topics such as General Linear Model and General Linear Model with repeated measure design as these two are also misunderstood

The last two vids of the series weren't too applicable to me, but I stuck around for a listen. Fantastic teacher, explained everything succinctly and in a helpful manner. Esp since I'm analyzing hard sciences data myself.

I watched all 7 with RAPT attention--you are a great teacher. Thank you so much!!

[@folliculostella]

Thanks Prof, you save a grad student from frustration. Statistics becomes more understandable when you explain it :)

[@kamranahsan1]

I had a great understanding of ANCOVA before but it's quite amazing to see the corresponding relationship between ANCOVA and regression.

[@serramuderrisoglu6893]

This is a wonderful series! Thank you so much! Your explanation makes complete sense, and I feel like I now understand what is going on with both (ANCOVA and MR) analyses!!

[@how2stats]

Thanks!

[@peterbolin2720]

I liked it, thank you for sharing this with us.
At first I was cringing a bit but it is interesting after taking some notes and seeing your thought process.

[@kipseremjacob9690]

Thanks, thanks so much, very interesting to follow from video1 to 7, so educative and makes one to long for more. great stuff here, kudos.

[@kinatone]

You are an excellent teacher!!!

[@kaili9264]

Thank you very much!!! You teaches much better than my teachers in medical college.

[@zilongzhang5595]

Yeah, thanks for talking about the corresponding relationship. Sometimes it is really tricky to choose one of these two methods.

[@kyzer7777]

awesome videos. Very clear and useful.Thank you

[@pabloarcadio]

Thank you very much how2stats for your videos. As a profesional statician I have to admite that you make me feel like I knew very little about stats. Go on with video tutorials.

[@kathrinho9136]

very helpful and good tutorial!!!

[@hirajpanosian]

really an eyeopener :) thank you so much!

[@matthewslocombe6271]

Thank you for the great videos. The comparison between ANCOVA and regression is really helpful! I have query regarding homogeneity of variance in ANCOVA and I was wondering if you could help - is there a method for running an ANCOVA (one between-participant factor with two groups and one continuous covariate) when there is unequal variance across the two groups?

[@samiraedres8970]

Thank you, did you do any videos about ANCOVA with multiple covariates?

[@DiegoBoada]

Great explanation. Thanks!

[@jonaskneer]

Nice lesson. Thanks.

[@Athenachandrasena]

Thankyou so much very useful. Can you also advice on how which values ideally can be quoted in the research manuscript finally

[@sharifmumu]

It's really a gteat video. Thanks -ShariF

[@andreaserrano3809]

Great Video, do you know how could I manage to develop my RESULTS after finding statistically differences among these participants? Which are the main values to report in my final results sheet? Thanks in advance!

[@mkhkheder]

Is it possible to get the data set so we can duplicate the results? or run it on a different software?

[@Ganadora13]

How do you do an ancova with 3 IV? Is it the same?
