You are a one stop shop for bio, chem and math. I went from not knowing order of operations to multiplying and dividing rational expressions in 4 months NOT thanks to professors or the math learning center but TO YOU. THANK YOU for everything you do for all of us. YOU are the only one that makes sense to me🤓

Very educative tutorial with well detailed information I appreciate, *The Semyon Tchernenko Strategy* was the only way i was able to get results. You can Google it.

For me he's statistics, math, finance and economics all im one as well😂

If my professor taught even remotely as good as this guy I'd be attending classes not just for my attendance

My statistics professor SUCKS! Literally paying thousands to be assigned a chapter with no other instruction, then take a mpc test following. I could have just bought the book and read it. Sadly, this seems to be the trend as this is the 3rd class I've had following this disgusting recipe. So, a huge thank you for this video. YOU deserve the "professor's" fee for actually teaching concepts and making them accessible and understandable. You've made my day.

@@jdj8168 so true

Love this! this 11 mins video explains way more than one hour stats class that I am paying for! Bless you

It's fuckin unbelievable that one person can be competent in that many subjects. You are the definition of true genius!!! Keep it up!!!

You are hands down the best person to go to for out of class material aid. You have helped me get through calculus courses and I still reference you while in an economics PhD program. Thank you so much for making these videos.

There is no doubt in this guy since I am watching his videos from the bigining when I first connected the internet, Thanks for everything

I've been struggling with these concepts until I saw your video. Super clear and detailed. Thanks!

Can’t emphasize how helpful this was. Thank you!

Thank you!! This is such a clear explanation. I am taking a grad class way over my head and my dissertation research is using surveys and we keep talking about PDFs and CDF and I have been so lost. So clear to me now, thanks bunches!

Thank the lord this explanation exists. Thank you.

you saved me. I was having so many problems with my probability course and was failing. I watched this and finally, everything start making some sense. Thanks a lot

You are bliss. I will always be thankful for the rest of my life to you. I wish my professor were as good as you.

Thank you for explaining the confusing topic in a simple way. Very clear and to the point explaination.

My notes from class make sense again. Thank you 😄

you have absolutely no idea how much you helped me...

organic tutor can never go out of style. we love you

One of the clearest explanations on a statistic topic that I have heard. Keep on going...

why can't my professor has 1/1000 of your teaching skills... You are the best!

Hey Man. I don't know you personally, but thank you for your contributions to my learning. Wherever you are , I will pray to god that you and family are in good health and spirits. Once again, thanks 😊.

This tutor is dependable. Thank you so very much for this clear explanation.

you just explained this so simply and I have been struggling so much with this. THANK YOU!

Amazing!! Thank you so much, way more better explanation than mi university teacher :)

Thank you, finally someone with a simple expanation, genius

from calculus I,II,III, discrete structures, computer org and now stats? YOU are OUR hero!!!!!!!!!!!!!!!!!!!!!!

this video is fire. thank you.

I love you! Thanks for the thorough explanation

Great explanations!

Thanks for the video! It was so helpful!

HELLLLLLL FINALLY THIS 0:55 CONCEPTS IS WHAT I HAVE BEEN LOOKING FOR!!!! THNKS MAN

Thanks. Great explanation. Thumbs up

"Area under the curve at that point to the left" One line that cleared all my doubts. Thank you

oh thanks! i just wanted a quick difference and here you go!!!

really thankful to u man wishing u a good health

honestly think I'm going crazy by the amount of things I have to learn for a VERY important test that I don't even have to do, but I still will do it because of extra credit and report participation, so I'm so thankful you're you her right now.

Thank you for posting this video

Great video as always!

Thank you very much for such a simple explanation, I wonder why Professors at college don't make it simple as you did here. They make it look much complicated than it is.

Thanks my tutor :D love it

not flawless, but holy cow. I understand PDFs and CDFs. Thanks man!

You’re truly great

This video makes cumulative distribution functions and probability density functions easier for me.

Very well explained.

great video sir! Thank you!

God bless you brother! Thank you!

Thank you again Mr. O-Chem Tutor

It’s true that the CDF for the uniform is (x-a)/(b-a) but if the entire area is not up to one, for instance, if b is the 70th percentile instead of the 100th, this implies the entire area adds up to 70 percent. The CDF changes. It’s the everything like before multiplied by 0.7. Props to this Professor, he is amazing for all courses, what else can this man not teach!

Excellent!

Finally I understood this thing. Thank youu

Thank you so much for such valuable video.

thank you sir the explanation was perfectt!!

Thank you man !

that was commendable 👏👏👏 thank U, sir.

Perfection at its best 💪...Awesome bro

Very nicely explained .

ur the best man

Thank you very much !

such a great help

wow awesome. Now, things are making sense !!!!!!!!!!

Many thanks !

This is much easier to understand than my online professors

Great topic thanks sir

I feel i have to pay for this. FYI🤣🤣 better than my lecturer

THANK YOU

thank you very much sir ...

Thank you!

شكرا على الشرح الرائع 🌟🌟🌟🌟🌟 Thank you You are a great teacher 🌟🌟🌟🌟🌟

You are awesome bro✌

thanks our brother keep it please

Bless you!!!

Thank you :)

The Area of line technically referes to an infintesimally area under the curve being a trapizium out the whole distribution equal to one.You can use the leibenz calculus theorem for that.

I took this lesson from a fake teacher called Masood. He just opens the pdf he found from internet and reads it and he dont even know what that means. And asking the questions probably he cant answer at midterm and finals. After understanding the problem i can finally be happy. Thanks to you

very helpful :)

thanks a lot, man. U deserve an oscar😁

When the video is soo engaging that you forget to like

I Fucking love this guy. no matter what im studying this guy has a video about it. AMAZING

Thanx a lot!

Impressive !

Thank you

really helpful

Thanks for the effort.

dont disrespect him boomer

My savior

@9:16 So to find area between a,b we just integrate pdf from b to a?

Good

i would have liked an explanation to why the CDF of a exponential is 1-e^(-(lambda)x)

@m.b.9026

It's because that's the integral from 0 to x. Which is the area under a function

Amazing

I find it very interesting that you don't even mention integrals once. What made you choose to do it that way?

Thanks

Hi How do I calculate p when I have chi-square?

What is area under CDF represent? I've tried it with exponential pdf, cdf with lambda 1 and integral of cdf seems to give me pdf.

OMG your voice is 100% similar to uki from nijien.

Well, it does explain why CDF is the integration of of PDF.

I am looking for bases that support the reasons why we do not add or subtract CDF. I wonder if anyone could help me find the rule

How can f(x) = 1((b-a) when there is no x in the function?

Why did he omit a lambda on a expression of exponential distribution, when he obtain a CDF of exponential distribution?

My man ate calculus😂!

What about the CDF and PDF for normal distribution?

Pdf tell you the shape of graph. Cdf tell you the left area of some value
