ANOVA stands for Analysis Of Variance. It’s used to compare the averages or means of two or more populations to better understand how they differ. In this SAS How To Tutorial, SAS’ Andy Ravenna walks through the steps to calculate values of an ANOVA table, and then shows you how to apply it in SAS.

Thanks everyone for your kind comments! I really enjoyed putting together this video so that you could get a thorough, baseline explanation to ANOVA. Please do let me know if you have any questions or comments. And also let me know what you would like to see as a topic in the future. Thanks! Andy

I can not thank you enough for this tutorial. I have been a SAS programmer in pharmaceutical industry for over 12 years and with no background in Statistics I have always struggled with ANOVA, even though I can write code in SAS for ANOVA. Today you have helped me to understand the one way ANOVA and I have not come across anything like your video. You made the whole tutorial so easy and interesting, truly grateful to you!

Hi Jose! Thanks again, for the suggestion. If you liked this video, you might want to check out the free Statistics 1 class, which focuses on more ANOVA and regression. You can find Statistics 1 and all our free classes here: 2.sas.com/6059Je2gP . You'll just need to sign in with your SAS Profile or set up a SAS Profile as part of the process. Also, you might find these user group papers to be of interest: 2.sas.com/6050Je2gu 2.sas.com/6051Je2gR 2.sas.com/6053Je2gT 2.sas.com/6054Je2gp

@andyravenna4222 2 года назад

Thank you Roger! That's very kind of you to say. What topic should I cover next?

@JohnPValentine 2 года назад

I’ll chime in…have you done one on logistic regression/survival analysis in SAS, Andy? I’d be really interested in that. Also I’d be interested in survey sampling in SAS, survey sample weighting, and dealing with existing survey data that has been weighted by demos (raked). Not sure if any of those are your wheelhouse though. Thanks for all the great videos!

Hi Michael! The topic of counterfactuals appears in a discussion of the SAS/STAT Causal Analysis procedures, as discussed here: 2.sas.com/6053MNpLW and the documentation lists some references that you may find useful.

@MaschlNES 2 года назад

I appreciate your way of explaining - it helps me understanding both statistics and how to put it in SAS. Would it be possible for you to make a proc mixed video, with random and fixed variables?

@SASUsers 2 года назад

Thank you for your feedback! We will be sure to share with the presenter.

@SASUsers 2 года назад

Hi: Thanks so much for your suggestion. We've forwarded the suggestion to our Curriculum Managers who decide on which analytic topics to record for RU-vid. In the meantime, to learn more about using PROC MIXED, you might want to refer to the overview and examples in the documentation, here: 2.sas.com/6051JbH1F or take a look at our Mixed Model Analysis class that feature PROC MIXED. here: 2.sas.com/6052JbH12 . Here's a blog post on the topic that you might find useful: 2.sas.com/6053JbH1N

@andyravenna4222 2 года назад

Thank you for your kind words, Ines. And thanks for the suggestion. I will definitely work with our Curriculum Managers to select the topic of my next video. We will move MIXED up the list :)

If an experiment was conducted at two and more locations, how to combine these over locations data during analysis?

@SASUsers 10 месяцев назад

Checking on this for you!

@SASUsers 10 месяцев назад

Unfortunately, we cannot provide detailed help or code or screen shots in this RU-vid feedback area. Our free Statistics 1 class covers performing ANOVA analysis and the examples in that class may help answer your question. To activate the Statistics 1 free e-learning class, visit this web site: 2.sas.com/6055PtfNv and scroll down until you see the section for Statistics 1 and then click the link to start the activation process. If you have a SAS site license at your company, you have 2 options for detailed support: 1) open a case with SAS Tech Support at support@sas.com and send them your site license number, the code you've tried and a small sample of your data, so they can help you with your question; or 2) post your question in the SAS Community Forum for Statistical Procedures here: 2.sas.com/6056PtfNa . We hope this helps!
