Statistics 101: ANOVA Post Hoc Test (Fisher's LSD) 

Can't wait to use ANOVA and Test on some data I'm tracking. Thanks for the videos. They're great! Very well presented and concise. Well done to you and thanks again!

I love your video, whenever i need clarity about statistical inference i follow you. Thanks.

Thanks! You make this easier to understand

thanks for the aside about the coasters. the wooden ones have an extra "scare" factor. giant dipper in santa cruz is one of those, but the King is over a mile?!? I love it. Thanks for these videos. you rock.

Thank you for this video, and to present the information so clearly!!

I highly recommend watching this tutorial

You are the best Brandon. Your videos are excellent and you make statistics very easy to grasp. Keep it up

As usual a very neat and clear presentation. Thanks a lot.

Incredibly Informative!!! Thanks Brandon, I subscribed.

your videos helps a lot

Great presentation, very helpful. Much appreciated.

I love your video. Really help me in my test! Thank you

Thanks Brandon!

Thank you very much. You are the best!

I love your videos, they helped me alott! will you please make one about PLS (partial least squares regression)

Thank you very much for your videos! :)

very good explained!

I love King's Island.. :) I have been there too.. 45 min drive from where I used to live .. lol

Thank you 😊

I love these videos

thanks ever so much man

9:18 "The alternative hypothesis that they are all not equal" should be "The alternative hypothesis that they are not all equal"

Thanks

A brilliant video like all your other videos. Thanks very much. One question. In this video, you compared the groups pairwise to identify which differences between the groups was significant. But what about the Type 1 error multiplicative effect for 3 groups. Why is this not a factor here?

Sir, please make tutorials for other post hoc analysis methods.

But where does this formula come from what's the theory behind it ?

Excellent work..... please Foltz what can I do if my data is non-normally distributed? what is the best method can I use instead of two-way ANOVA.

In case of Beast VS Banshee we compared p-value with 0.05 but in case of Beast VS DiamondBack we compared it with 0.001, why ?

4:24 what if the 3º value is not relevant for the comparison between 1 and 2, in addition to be completely independent from the 2º value? And the variance of these 3º value is masking the difference between 1 and 2?

"Fisher’s LSD, which is the F test, followed by ordinary t-tests among all pairs of means, but only if the F-test rejects the null hypothesis. The F-test provides the overall protection against rejecting H0 when it is true."

At 7:57 point three: shouldn't it be "sample pair" instead of "population pair"?

please explain when the 0.5 significance level is compounded, and when not. I see you doing t tests comparing each one individually in this video. Please help

I find it hard to understand the part with error compounding. I mean, I know that in probability if two events are independent and have let's say a probability of 0.05 of happening (In our case Type One Error). Then if we want to repeat the experiment let's say 3 times, then we set P(Error) = 0.05 and then we have 0.05 ^3 = 0.0125%. So at the end we decreased our P(E) by repeating the experiment 3 times. I'm I getting something wrong here, can your please help me understand this concept? Thanks.

9:20 13:42 How is MSE Mean Square Error calculated?

Morning sir, Which Post Hoc Test can we use for a TWO WAY ANOVA? W/O replication thanks.

I hace tree samples for tomatoes in differents mature states. Can I use LSD ?

8:51 when I put the same table in excel and run one way ANOVA: Single Factor, it gave me different results. I am facing problems with these statistical techniques when I perform them in excel. Please help me

could anyone told me how to do LSD in two factor anova without replication??
