What is a p-value? 

Oh, it's a puppy value. Got it now

I sat down for 2 hours reading/watching about p-value thinking how this is so counter intuitive...then I watched your video...EVERYTHING MAKES SENSE! You're my hero (and Fido)!!

4 years of math degree and i've never heard a better explanation. thanks

This is fantastic, please continue this series. Also, I have an 8 year old and you are correct, the entropy increases dramatically.

i think many people wont realize actually how brilliant u explained ... thank u

Thank you :-) You're always a true inspiration. It's clear you're new on YT, but please, keep going and polish the videos you're providing. Your previous articles were amazing. Please translate them into video lectures and build your brand here as true decision scientist. This is gonna be a revolution! :-)

Wow !! What an simple way to make even a newbie understand what's p value ! And the way you've described, it also allows the educated audience to infer that the magic lies in constructing the null hypothesis world !! Thanks for the video ..

I have no formal education but that's only because the Grateful Dead used to tour. Now that they're long retired I have a bit more free time to flail about in many advanced fields. What I've discovered is there are certain teachers that can make the most fascinating, mind blowing subjects as engaging as watching paint dry. Then there are teachers that can take a subject that, at first glance, has the appeal of eating mouthfuls of dirt, but after a few moments you realize you're gripped with increasing excitement. You are the latter. I know I'm late to your channel and blog, but I hope you continue on. You are very helpful, illuminating and funny! You had me at puppies but I lost it at "8 year old are evil." Who woulda thunk statistics could be so fun? THANK YOU.

So clearly explained. Never fully understood the explanation even in "reputed" books. Thanks!

Wow! Explained this way it gets soooo easy to understand. Brilliant video!

Most amazing p-value explanation ever!

Albert Einstein had it right: “Education is not the learning of facts, but the training of the mind to think.” And this series prove it. Keep it on. I would like to learn how to think.

Brilliant explanation. I wish I could tell you in words as to how confused I was about this till I found your video. Really liked your example.. thank you so much :)

Thanks Cassie......i was struggling with the p-value......it just turned out that I had not thought of it in the right way

Great video! Your tone, and cadence and voice is a nice change of pace to listen too as well!

Bravo Cassie, I like your style of narration :-)

I adore your explanations! Period.

Thank you for these ! please keep them coming

Finally made sense after watching 5-6 videos... thanks so much Fido!

Completely amazed about you! Very great work!

Amazing explanation! Thanks for sharing it! You made my world better!

Very well explained, thanks a lot Would love to see more content on statistics basics

Simply incredible. I can't find words to express how I am grateful for this explanation!

OMG! You simplified the explanation of a p-value beautifully. I love the puppy example, metaphors help. Thank you so much 👃

Hi Cassie, greetings from Dominican Republic. Great video, a lot of people struggle to understand some stats concepts, but then someone like you show us the light at the end of the road. We really appreciate your effort. Ah and the next time we run out of cookies, i´m going to applied p-value, but guess what? P-Value=my 4 year son. see you...

OOOHHH MY GOOODDD..... I have been trying to understand p-values for such a long time but I was not able to!! THIS IS A BRILLIANT EXPLANATION

One of the best 3min vid I have ever seen.

I love your explanations. they are brilliant.

This was such a good explanation. Thank you!

Thank you for explaining it so easily!

Thats the most brilliant and closer explaination found on youtube till now...... 👌👌👌👌👍👍👍👍🌹🌹🌹🌹🌹

Very neat explanation!

the explanation that i was looking for, thanks!

I love your explanation!

Thank you so much for the wonderful explanation! Please keep sharing :)

holy sh this is the best video i've watched im taking ap psych and i had no clue what this meant. thank yo uso much

Great explanation, thank you!

I just loved this video! thanks a lot for sharing x

Everything in this video is just beautiful.

Awesome video! Love your explanation. I didn’t know stats could be funny :D

Wow..that's the simplest way to teach p-value. thank you

Wow. Some inspiration there. Good Job!

It's amazing!!! I loved!

Very good explanation and lovely accent

This is real intelligence, defining complicated concepts in an easy manner.

Great video!

Loved everything abt the video except your boss trying to throw ads before I can actually watch it! Seriously - if someone’s willing to watch a video on p-value spate them the ads! Can’t believe you have an 8 year old either-well done!

I have started a course in Data Analysis and p-values are, of course, involved. And the past week I struggled to fully comprehend p-values and the entire analysis thereof, but your explanation has helped a great deal. Thank you so much!

Very clever explanation.

You mate just earned your self a sub!

Thank you so much! Great for my students.

i love your videos!!! Thank you

Someone's starting a vlog ;) Thanks, Cassie!

beautiful explaination

Thank you. You're great!

I love you... Finally I understand p value

best explanation ever!

the puppies did help! thanks!

Thank you very much! Now, I understand it!

... constructed as to what was learned from putting to use statistic(s) testing of a sufficient sample wrought from the whole of that world, as held out to exist, arbeit while not necessarily having been in a reasonable position to access and assess the whole of all possible words of all sizes beforehand. :)

Thanks for this.

I'm years late to this but wow, this was helpful.

Damn now I have to calculate p-value every time when my dog messed up my room. Gr8 explanation loved it.

Low pvals means low entropy, low surprise, ordered and expected distribution of reality?

Couldn’t wrap my head around the puppy concept. However, it included puppies, so it’s a win for me.

Amazing!

Are you serious??? I just spent so much time trying to understand what the heck the p-value was. You broke it down so easily.

That's a great contribution, I will steal it (with a reference 0:)).

Thank you for saving my brain cells that were about to be destroyed by watching several other videos on p-values 〒▽〒

Rarely leave a positive comment, but it was a very nice video! Thumbs up for you and (not) innocent Fido.

Super I have done something similar to it to explain students. BRAVO Cassie!

Thank you very much! I suppose I've finally got it.

thank you

I didn't fully understand it yet, but she has a reaaaaally good voice and sense of humor and yea I can hear her voice all night long

Excellent

Great!

Thanks ❤

You have a beautiful mind

Awesome!

dunno why but her voice is kinda mesmerizing

Great 👍

спасибо!

THANK YOU!!!!!!!!!!!!!!!!

Wow! You think you were taught p-value badly. I was just told a formula to calculate it and compare it to 0.05 for some reason to accept or reject the null hypothesis. I am glad I don't do stats for a living. However, it would be worth wondering that with the base knowledge that I got, could I ever be a statistician in my life!? I think my course's name should have been "How to pass the stats course but fail life 101"

unbelievable. thank you :=)

Genious

Thanks

I love youuuuuuuuuu

Chicken or egg problem / Dealer's choice I reckon, oh yes I do, because, duh, duh, duh -- If you understand the purpose and use of null hypotheses before attempting to convey p-values vis-à-vis to them, _and_ have some basic understanding of probabilities then it seems to me you're well on your way to estimating something somehow.

This is how we learn...through story.

Okay, you said the p-value is a probability that the result is that ridiculous in a world where the dog didn't do that. But I hear statisticians tell me all the freaking time that the p-value is NOT a probability. So what am I getting wrong here? There are so many conflicting statements about that goddamn p-value I don't know where to start. I just see it as a tool to distinguish the signal from the noise with some sort of confidence, not more, not less.

But, also, no, I'm swilling down my third cup of coffee today. Sleepy would not be the word for it. Assertion denied. 🤪

The p-value of a dog alone in the house for a long while is probably quite high.

yeah, the puppies helped indeed :)

Well it's said that if you want to know how well you know a particular topic. Just try to explain to a 5 yrs old kid, if he understands it well, you know the topic well. And i must tell you, you know what p- value is???? ❤

Ah, I edit, therefore I subsist in persisting.

OK, it's like when the doctor told me I had been diagnosed as a total paranoiac... OK, OK, OK... so, that does not mean someone is not following me and trying to kill me... Conclusion, Fido is innocent. PS, I love your presentation

Thanks for the effort. The null still makes no sense to me. At all.

p(D|H0). This is p-value :) There is nothing mysterious about it . It's just that it doesn't fit into the definition of frequentist probability, so they dont call it "probability".

👏👏
