It’s great to hear that it is helpful!

[@arjaydeleon5996]

Thank you very much. I learned a lot in this almost 22 minute video than in our 3 hours class. I was so confuse during our lecture. Thank you very much sir.

THIS IS HELPFUL, IF I MAY ASK SIR WHY IS IT ONE TAIL?

[@emmanuellaokoro901]

Thank you so much , this was absolutely helpful! pls what figures would we get to be able to support Ho and reject Ha? .

[@aachinthaka7311]

Thanks a lot. Very nicely explained.

Thanks for watching!

[@robinakhaliq5451]

Sir If we have 30 values in our table so it's very difficult , time taking to find total some of square .... So do you know any shortcut to calculate total some of square by using calculator

[@dmcguckian]

It depends on the calculator. Graphing calculators allow you to calculate the sum of squares with a built in program or you can enter everything into a list and then tell the calculator to square the list and tell it to sum the list. For my students, I try to give them the sum of the squared values on the exam to save them time.

[@beast2542]

well appreciated. 🙏

[@dmcguckian]

Thanks

[@evanpenas9594]

is two treatments enough for crd?

[@dmcguckian]

Yes, but then the test is equivalent to the independent t test.

Thank you so so so so so so much

[@noturecologist]

In getting the fstatistic from dividing mst to mse my answer is 3.61, where did i go wrong sir?

[@Samy-xt7nu]

Immensely helpful

[@dmcguckian]

Glad to hear it was helpful!

Wao so welll like this ❤️ love 💕 from Pakistan

[@dmcguckian]

Thank you!

[@kujayasinghe9199]

Thank you so much for this video! I really admire your teaching style! Btw, the answer I got for sum of treatments is 92.942925. Why am I not getting the answer you have there? Please clarify! Regards

[@sel9358]

Where did 92,97 come from?

[@labomba8206]

thanksssssssss 😭😭❤️❤️ explanation of parameter estimate for the model

[@fredrickantwiafrifa9364]

Thanks so much. The only problem I have is, you skipped something around the summation of Yi squared - CF so I don't get that part. Any help?

[@dmcguckian]

The sum of yi squared is found by squaring every value in the original data and adding them together. If you had 3 values only, 2, 6, and 10, you would get: 4+36+100=140. To get the correction factor, you add the original data values together and square the sum. Then divide that by the number of values: (2+6+10)=18, then we perform 18(18)/3=108

[@fredrickantwiafrifa9364]

@@dmcguckian Thanks so much. I found it in the problem 2.

[@sullivandwyer9230]

blessed

[@mercy_amoka]

Thank you sir, for helping students like me understand this topic better, I have a question tho, this Correction Factor explained in this video, is it necessary to square the sum of the Yij values before dividing by n? because I noticed some people don't.

[@dmcguckian]

Yes, it needs to be squared if you’re using the approach I used in the video.

[@mercy_amoka]

@@dmcguckian Alright sir, thanks for clarifying.🙏

[@eternal6323]

So basically CRD is for one way anova, and rbd is for two way?

[@dmcguckian]

Yes, but the RBD assumes that there is no interaction between the two factors.

[@jessiequilantang3298]

why was the df decreased by one?

[@dmcguckian]

Hi Jessie, there are a few degrees of freedom in this problem, so I am not sure which one you are asking about. However, in general, for every estimate the data is used for the number of values is reduced by one. For example, if n values are used to estimate the mean, you would have n-1 degrees of freedom.

[@jessiequilantang3298]

@@dmcguckian oh thank you I literally forgot about that AHHAHAHA

[@ayas-3390]

You should learn how to use calculators for these calculation😎

[@dmcguckian]

😆 I have videos on that if you need to learn.
