This is the BEST explanation of ANCOVA I've heard yet, and I am so glad to finally understand how to apply it to my research properly! Thank you SO much!
It's tough to subscribe to anyone on RU-vid, but what you have presented here has given me the impression to subscribe. Thanks for the clarity, and keep on the excellent work.
Big B is back!!! (I thought i was alone in this tough neighborhood called statistics...but Brandon's back to guide us through.!!!!) So glad to see you're still doing these videos!!!!! Stats to me is such a "beautiful and alluring... but hard to approach creature"I am getting there slowly however. I am still pushing my way through my classes but I plan on contributing towards the continued development of some of the best videos out there. (as all who benefit should if they can...from these videos!!!!! Folks at my university are calling out your videos by name ("That Foltz guy is the best for...") to students looking for the best entrance into the world of Statistics. THANK YOU SIR!!!!!
This is so helpful and easy to understand! I just got a job in statistical programming though I am an infant in statistics. Thank you Brandon for raising me to the teenage :)
Thank you. Very well done. I hope you do the next video w/ complete examples and visuals like your "Statistics 101: One-way ANOVA, A Visual Tutorial" Thanks again for creating this.
Very great explanation, more clear, much better than the current course "Learning Statistics" taught by a Harvey Mudd College professor in "Great Courses Plus".
What you mean by saying "3. how can we CONTROL for initial differences between groups either due to chance or because observations cannot be randomized fully?'
Hi Brandon, Thanks for the video, it's my first time here and I thought was very helpful. However, I've a question about the covariate. Is the covariate supposed to be continuous or I can also use a categorical variable as a covariate? I've been told that covariate is always continuously measured and a cofactor may be categorical. I'm used to work with SPSS and we have different boxes to set up. I know you're busy, but I'd appreciate if you take a time to answer me. Thank you!
Amazing video I learned a lot! I have a quick question, if I only have two populations to compare (for instance year 1 and year 2), and I still want to put GPA in as a covariate. Would ANCOVA still be the best option here? Thank you very much!!
Yes you can! A few ways to approach it but in that case you would have two feature variables and then the target. Feature 1 would be the year (binary: 0 and 1) and Feature 2 the GPA continuous covariate. Thanks for watching Haopeng!
Hi I am currently doing a research and I am confuse of using which statistical analysis in my hypothesis. If I would like to test the hypothesis "Is there a significant effect of gender differences and personality traits influence on mate selection?" Which statistical analysis should I use?
Sir, could you please tell, which screen recorder and video editing tools you use for content creation. I'm looking for a reliable screen recorder and video editor for making R programming videos. In past 6 month, I have used movie maker for video editing but from this year January Microsoft discontinued support for movie maker in win 10.
Sherridon Sweeney A factorial ANOVA just means that you have more than one “level” of grouping for your independent variable, and these levels are basically discrete. In ANCOVA you have a second factor called a “covariate” that influences your results, and the idea is to basically remove the effects of the covariate. This way, the means of the groups can be evaluated as basically what they WOULD have been if they had started out on an equal footing without the covariate factor affecting the results.
So basically, ANCOVA seeks to reduce both random and systematic error by considering the influence of one or more covariates on the dependent variable.
