Lesson 1 - What is the F-Distribution in Statistics?

[@nielakshi3132]

Hello sir, Thank you so much for such a crystal clear and detailed video. I had missed the lecture on f-distribution and I was quite scared that I might not be able to understand it. But someone recommended me going for KZbin classes and I don't regret coming here at all. Your video is so informative and I understood the whole topic easily. Thank you again. Have a good day/night....💜

[@pedrocolangelo2458]

Sir, you are like a god teaching. Ok, excusing the previous joke now. You have a didactic skill that only few people are born with it. Thank you for these videos!

[@vincentagbe5709]

I like the way you make your video. It makes me understand better as you explain in details. Thank you Sir

[@TonyTongWA]

Great video, thanks for explaining things much clearer than my college prof! Looking forward to hear your explanation on ANOVA and partial F-test!

[@MathAndScience]

You are very welcome!

[@gayatrimagi]

Explained so simply and brilliantly. Thank you

[@sannguyenngoc8705]

A big thanks for such a clear and made-easy explanation

[@MathAndScience]

So happy you liked it! Jason, MathAndScience.com

[@Minerva734]

This was a really good explanation. I struggle with stats but I understood this.

[@jab5569]

Thanks for creating this video, I learned a lot. That said, perhaps start with concept, drawing, example problem then the in-depth description? It took five mins to know why and how we'd use this distribution. Eg, tell them what you're going to tell them; tell them; tell them what you told them. Just my .02.

[@gregn5389]

Subscript of variance under population x2 should be 2?

[@alexismartinez8868]

Excellent video, could you explain more about degrees of freedom in statistics? and about the ANOVA thx

[@miskemarsogi8388]

i still dont get it.. if F is 5.5 with p-value

[@raghavagrawal9861]

great video Jason....I simply loved the videos...!!

[@bchaitu]

Who else was waiting all the time for him to correct the population variance (σ) of population 2 (σ1 → σ2)? :D Great video, though!

[@feebee1982]

Thank you so much, you have done an outstanding job explaining!

[@ashrafta4188]

Excellent videos, congratulation, I need to subscribe this channel

[@nthattempt9352]

Hey. Thank you for the video's, they are helpful. Please may you re-organise the content, I am finding it difficult to move from one video to the next. Regards.

[@adarshjha3922]

great explanation

[@suhailawm]

Tnx alot sir. From srilanka

[@srisatya1630]

What is the real life example for f-distribution

[@abraham4813]

Thank you for efforts, sir.

[@JD-ol7sh]

REALLY well-done. Thank you.

[@alexismartinez8868]

awesome thanks, could you talk about degrees of fredom and anova and design of experiment? pls

[@AnilKumar-qd9eo]

Sir how to find the percentile value of f distribution with given two degree of freedom ?

[@MbowaSamson]

It's really nice

[@andrewchase3807]

Does this require a normal distribution?

[@latanezimbardo7129]

very student friendly Thanks!

[@mohammaddawodieh4098]

Thanks for explaining, when will you post the next section?

[@jordanjtbraun]

I would move away from using the IQ tests as an example here, as it is a standardized test. So, supposedly the way it was formed was to give a test to a bunch of people. Then score the test. The mean test score was given the number 100. So if someone was "average" intelligence, then they would score a 100. So what ever general population you are using, you should get an average of 100 for an IQ score. If the mean of your population is scoring 85, then they are lower in the test performance than the average. I would agree, however, that IQ tests are inadequate to evaluate ones ability and mental capacity. IQ tests simply test how well one takes tests, not necessarily how well they can do other things, such as shoot an arrow or swim fast. They are not the end all and be all, but they do give us a specific amount of information about certain cognitive capacity a group has. So it does have value. But its value is not in assigning a person their worth.

[@yazanalkassem2473]

Thank you very much!

[@crisli.b6314]

thank you bout this but could you also put a link on that T distribution and other stuff that you have mentioned on the video? thanks. salamat! :)

[@onyameabasa]

How i wish he could be my mentor

[@nourammar4368]

thank you Sir

[@sdsa007]

Thanks!

[@trishahipolito7177]

thankyou!!!

[@fundementalroast7002]

Do you do manova?

[@0xoRial]

It is not clear what y-axis on the graph means. you have one number s12, second number s22, divide one by other and suddenly get a 2d distribution o_O. ps. I had statistics class 10 years ago and trying to refresh memory, perhaps that is why I am missing some piece of information...

[@44분]

damn you're better than my prof.

[@ndoli7872]

please share statistic textbook or your notes pdf

[@bathama.k.7759]

thanks sir

[@yahyazahlane1337]

Thanks a ton sir : )

[@litongj6227]

very detailed:)

[@MathAndScience]

Thank you! Cheers!

[@youcefk7843]

Thanks so much

[@akshayak435]

I don't understand, u have variance of 2 samples and u r testing if they r equal or not wtf, just look at values n see if they r equal or not

[@juanperon2466]

Well, actually they're never equal to be fair, but you want to check if the measured difference is big enough to proudly and without any question say that they're not equal.

[@shujiezhang3494]

The pace is a bit slow.

[@sushmagavde1982]

Let x &y f disturbution with (3,6) & (6,3) d. F. Respectively find the value of p(x0.1)... solve this problem .... I dont come this problem

[@melissakelley5867]

So your symbols are not clear what you call a sigma symbol looks like the standard deviation symbol

[@MathAndScience]

Yes of course, that "standard deviation symbol" that you re referring to is the lower case greek letter sigma. The upper case sigma looks like the bit "E looking thing". Lower case sigma is what I am drawing here. So that standard deviation symbol is a sigma.

[@Kryptsanies]

Yes intelligence tests are real and IQ tests highly correlate with intelligence. This finding is one of the most replicable in all of psychology, but people hate the message.

[@iMutt-yy6vf]

you should look up the term "reification"

[@bigflakes6699]

wewe bana!

[@naaritalks]

great

Where is the math? The proofs?

[@xavierdsouza8885]

why do u sound like salman khan

[@aliceliu8232]

Couldn't play it smoothly,buffering every several seconds,tough I am using VPN,none of other youtube videos had such difficulty of playing.

[@MsShenjie]

Very clear and helpful!thanks!

Thank you so much
