This is the next video in our series about the analysis of variance, or ANOVA.; more specifically the Two-Way ANOVA. To make the topic more manageable, I have divided this video into two parts. In Part 1 we will discuss the conceptual background using graphics and charts and then in Part 2 we will go into Microsoft Excel to conduct a "hand" calculation of a Two-Way ANOVA and also solve our example using Excel's built-in data analysis tools.
There are several types of ANOVAs. In this video, we will be focusing on the Two-Way ANOVA which itself comes in two flavors; without replication and with replication. In this video, we will be learning about the Two-Way ANOVA without replication; also known as the completely randomized block design.
If you are new to ANOVA or are still trying to figure out exactly what it is...this video is for you. So sit back, relax, and let's go ahead and get to work.

Thank you for these great tutorials! The slow and detail approach combined with visual descriptions really helped me understand the problem thoroughly.

@lala.grateful 6 лет назад

I just wanna pop by and say thanks! Your stats videos are awesome! Those complex stats concepts were explained in a simple and visually helpful way without lacking the depth. You've made the concepts easy to understand! Please continue to make more videos on, e.g. neural networks, machine learning, decision tree, cluster analysis, factor analysis etc.

@munierhossain6412 4 года назад

Thanks Brandon for your great series. I am not a statistician by training but hold an amateur interest and have been teaching basic stats to medics for a few years. I am a visual learner and I like your attempts to break things down and explain with visual graphs.

@ann-mariecastille9369 4 года назад

Thanks so much for your extremely professional video! I am teaching stats and a student asked me a difficult question about this type of ANOVA that I feel like I inadequately answered. I'm going to show them this video to clarify things.

@desiadaven 8 лет назад

These videos are super helpful! One thing that may be worth considering is numbering the videos so we know which sequence to watch them if we are to start from the beginning and build from there.

@laapozle 10 лет назад

BRANDON: Eres el mejor maestro que he visto en mi vida. Que lastima que no ensenies en CSUS! After a semester of straggling with STATS, you made my life easy with just couple videos, Thank you so much!!!

@BrandonFoltz 11 лет назад

Blocking doesn't "eliminate" row variance per se; it accounts for it. The total variance is split up into column/group variance, row/block variance and then what ever is left is error variance. If the error variance is small, then most of the overall variance is in the columns and/or blocks; which is another way of saying, that is where there are differences in the means.

@olivierlaverde9771 Год назад

your classes are really good, i've been strugglin with this subject fo a while and your videos are really helping alot, even though english is not my first language i can understand better than my brazilian teacher trying to teach it, thank you very much!

@telesphoremarie1514 2 года назад

I have always struggled with statistics... BUT your videos prepared me the night before my PhD comprehensive exam... Which is right now... You are soo good, that I took the time to make this comment even though tomorrow morning is the real deal.... And many of yous will be like "heyyy, he's a PhD and doesn't know the foundation of stats??!!". And I'm like "Yoooo, it is my weakness and I scratched by up to this point without knowing the depths". Then yous will maybe say "Broooo that's not good man". Then I will emphasize "Yeeeaaa maaaan, it's bad, and that's why I came here, and gosh-darned it was effective thanks to Brandon Foltz".

@saketdeshmukh6881 10 лет назад

Hi Bandon this concept which most of the statistics professors struggle to explain are explained in so lucid language that even a primary students can understand them. thanks I have one request please could you also explain linear model using anova specially it is executed using sas EM expalaining roles of variable and output.

@shivampatel-zp3tb 8 лет назад

great explanation ..thanx a lot ...

@TonyIngramPhD 10 лет назад

These videos are great. Thank you so much for making them. Very clear descriptions, which is rare in statistics. Also clarifying how things have many names helps big time. I'm still not 100% on one thing: how exactly is Repeated Measures different from Two-way without replication? When I see how the data is laid out, it looks pretty similar, doesn't it?

@BrandonFoltz 10 лет назад

Hi Tony! Yes the layout of the tabular data in a randomized block design and repeated measures design are similar. However the difference is evident in the name. A randomized block design is well, randomized but in the repeated measures it is not; each subject acts as his/her own control (doesn't have to be a person per se). So in repeated measures, we are only interested in how each subject changes over time. We do not concern ourselves with the differences between subjects. The only subject that matters to any given subject is itself. Does that make any sense? LOL :) - B

@michalchik 5 лет назад

Brandon great series of videos. I am sure they are very helpful to many students and i use them with many of my students. You are patient and clear. I have one suggestion about positive message in the video introduction. Please contact me if you are interested. It's a subtle point.
