"you cant roll a 7 on any dice I've seen" I see someone who has never played D&D before
. Thank for the video btw.
haha. No d20s in my games cupboard, unfortunately.
First thing I thought too! LOL
I thought that instantly
What's funny is that on this exact moment of the video I thought exactly the same, went to the comment section to write it and I see that's its already there haha
@@kamilnowak4329 You perfectly described what just happened to me! Ok back to the video now.
bloody rippa mate. you really got the knack of explaining rather than just telling.
ridgy didge feedback right here^^
My first month of Prob. and Stat. lectures and these concepts were still lost on me. I now feel such a wave of understanding that the euphoria can hardly be contained. Thank you!
One of the best explanation of PDF, CDF, PMF across CZcams. Your channel is so underrated. This video deserves million views.
Oh but it's worth it just for this one view. Thanks Azan!
@@zedstatistics Love how humble you are; read your papers on biostatistics the other day. Not that I understand all (or much) of it, but massive respect and great channel! Much love. Please make many more videos!
soooo true
Can u explain to me, where did he fine all those number out of 1/6 probability pl?
This video now has one million views!!
Everything in this video is perfect
Examples : we can easily imagine
Video : perfect
Voice :not having high pitch
Everything is amazing
I have just watched half the video and can't hold myself back from Thanking you for putting a video with such a clear explanation. I had watched 7-8 videos on You Tube before I found this..Simply Superb
I think your ability to explain this concept in such a succinct and clear way really speaks volumes about your grasp on the concepts - it's just as they say; you don't understand a concept until you can explain it really well to someone else. super helpful video!!
well done mate! very few people have art of explaining things perfectly (method, pitch voice, pace, graphics and more) and of course it comes naturally. You are one of them. keep it up!!
I’ve been viewing a lot of stats videos on CZcams and there are a lot of very talented teachers that can explain this tricky subject. But, this channel is the very best of the best!
Can't believe 16 minutes back I was struggling with this topic.
Thank you for this great lecture! It was so easy to follow. This was my first video on this channel and I didn't even give a second thought and just subscribed.
You precede me by 3 months. You were stuck 3 months back where I was 16 minutes ago. And in spite of this being the only video I have watched, I too subscribed to the channel, with no second thoughts.
You precede me by a year and I share the same sentiments. I, too, will now subscribe.
lol. me too. now i gotta find differentiation and integration examples though
I have been through almost 10 videos to understand the y-axis of a pdf and this nailed it!
Classic way of presenting and teaching. Absolutely loved it.
Hey man,
I would like to take a minute to thank you for your videos. They are so clearly explained, to the point explained in short videos. Really helped in gaining a good grasp of the concepts intuitively and please continue this work of helping students like me.
Holy crap this is perfect. Thank you so much. Once I hit this point in statistics, I have felt lost. The more videos covering this type of stuff, the better!
So grateful for your videos. Your teaching style is so natural and suitable for 'stats idiots' like me :) I'm probably the one who's always raising her hand to ask a question but the teacher ignores/misses my raised hand. Most stats videos I've watched assume the viewer understands everything then jumps to the next level. But you actually take the time to make sure your point is understood before moving on. Thank you so much for your superb teaching!
that transition from stats to calculus was super smooth and intuitive. Z, we NEED a calculus tutorial from you. It would make school SO much easier.
You shud refer to Professor Leonard
I have to say; I've had professors throw around the terms PDF, PMF and CDF in class. While I understood that PMF referred to discrete functions and PDF to continuous functions, I never really understood the relationship to CDF until watching this video. Thank you so much, this was excellently done.
Finally! Someone who has explained these concepts in a way that makes sense. Thank you!!
You are what the kind of professors I aspire to be. Super clear, thank you!
You are doing a great service to those who got lost in understanding statistics. Keep up the good work.
I have subscribed! There is coherence, clarity and fluency. Everything in this video works together for the betterment of your resource. Thank you!
I suggest for a video giving real-life examples and situations that will further explain the topic. By the way, I love your introduction stating that it is more intuitive.
You definitely saved my life. The objective of teaching is making learners easily understand the content and your videos do a very good job. Thank you and hope you have more representative and informative videos like this.
This is probably the best explanation of PMF, PDF and CDF on youtube. Thanks a lot.
Thank you!! I really needed it for an article called Predicting the Probability of Correct Classification, it's unbelievable how you explain these concepts in an easy way!
Thank you so much mate! Like you said, very intuitive. This style of teaching really works for me!
Such a great and easy going explanation.. go on, please.
Thank you so much, I have struggled all the way in my undergrad to understand the difference between a c.d.f and p.d.f, no one could explain it to me better. This is perfect, just as I am starting my Ms.
Thank you so much for such a clear and straightforward explanation. The graphs were very well done. This cleared up my confusion between PDF and CDF.
You put everything so nicely. I have studied the same concepts multiple times but never have I ever actually understood them.
Thank you
First I would like I would like to congratulate you on an excellent series of stats videos. You have a talent of presenting difficult concepts in a simple way and demonstrate that stats is not boring, but exciting method of data exploration. I teach stats at graduate level for biomedical programs. You lectures helped me to structure my courses to capitalize on intuition and understanding. I highly recommend your lectures for students and professors alike at any level . Best of luck
I have been searching for hours and I am so glad I found your video. Best explanation of PDF, PMF and CDF hands down.
The explanation is an "Art", You are the "Artist".
No one can explain better than this.
Thanks for saving my time going here and there, did a lot.
you are awesome man. I am learning datascience and i just can't explain how much your videos are helping me. Being from a computer science background i have no idea towards statistics and your explanations were tooo goood,
just going to recommend to all my fellow datascience folks who are struggling in the area of stats. Thank you
Thanks for the videos! I'm about to start a master's this year and the videos have been helpful to refresh and gain a deeper understanding of stats!
Thank you for making this video! The best I’ve seen on PDF, CDF. That last bit was pure gold 👏
Thank you! I'm taking mathematical statistics right now and were covering CDF and PDF using differentiation and integration and I finally understand. Thanks again!!!
wow one of the best videos I ever have seen. Thank you for taking the time to explain to us.
thank you so much for your videos! i have to do 4 stats units at uni and i'm on my 2nd so far. your videos helped me revised what i have learnt, thank you and keep up the great work. I wish you were my lecturer
These videos are so helpful! You truly make learning this material intuitive! Thank you so much!
You're the first youtuber i saw create a section on the video progress bar and it looks neat.Keep up the good works 💪🏽💪🏽💪🏽
I don't even study or use this stuff anymore but the way you put it is just so satisfying to see
That's why you're special, providing us with all that intuitive sense of statistics which other internet and college sources lack.
What a GREAT intuitive explanation of distribution functions! I can tell your videos will come in useful throughout my Probability course! (and statistics course once that comes along) :)
Clearest explanation I've encountered so far! Thank you!
I'm about to take the qualifying exam in PhD and your's is a substantial help. Thanks
Amazing, superb, very good, excellent explanation. He teaches first intuition behind the pdf, pmf, and cdf, then teaches how the formula is working. You have explained very patiently that almost everyone would be able to keep up with what you are teaching
Why don't this channel have more subscribers?!
This is the best statistic video I've ever watched on ytb. It cleared my doubts halfway through the video. Thank you so much for this. You're really good at explaining things easily and clearly.
Spread the word, PL. It's the little channel that could.
have to say you explain stats concepts really well. very easy and intuitive to understand.
Thank you so much! This video explained PDF and CDF so clearly, I was struggling to understand the graphical relationship and you explained it so well!!!
I've been learning this for weeks and you explained it to me way better in like 10 min
Thank you for such a well-explained video! Really helps understand the concept with ease and clarity! Thanks!
This is beautiful, honestly. Thank you soo much.
YOU ARE JUST THE BEST AT EXPLAINING THIS! Please continue!
This was my first lecture related to stats and maths in which I dind't get bore. You just took the video to a whole another level of interest. God, the music itself was so interesting!!
by far, best explanation of PMF PDF and CDF on youtube.
Wow...!! This is great. This video helped me sort out so many confusions and put everything into perspective. Thank you for this simple yet valuable video.
life saver!! explains the concepts really well with visual representations. Thank you.
Thank you so much! You explain in an intuitive way the importance of the accumulative fct!
Had to write a comment to thank you for this video, we covered this in my first year stats unit, and the lecturer has delivered the entire content of this part of the unit almost entirely in maths notation and mathematical definitions that left me puzzled and wondering whether I had registered for the wrong class, in the 16 minutes from your video I understand the content far better then I did after watching hours of lectures on the exact same topic
Absolutely adore your videos, especially the series on distributions. I’m sure these are in the works, but could you do videos on the Geometric, Beta, Gamma, Weibull, Pareto, Logistic, and their inverses of those that have them? Really get into the guts of each...
got much planned this year! Hope to get to these but they do take a while :) Have got this comment screenshotted and will give you a shout out when I hit the whole Beta-Gamma functions :)
One of the best videos till now I've come across on PDFs!
Thank you so much, I've been trying to understand this concepts for the longest time!
Something in your video made me focus more while learning. Thanks!
beautifully explained, keep going on all statistical concepts
Amazing!! As smoothly and simply explained as possible
Very nice and simple explanation that just hits the nail on the head!!!
YOU ARE THE BEST! I am following you fron Austria and you have saved me so much time through this great video. I'll make sure I buy you a beer or two when I go to visit a friend in OZ next year. Thank you, thank you, thank you!
I am not from mathematics background. this video beautifully simplified such a complicated issue. thanks. God bless you
thank you so much for the wonderful explanation, the visuals sure made the concept easier to understand
Such a helpful video. Great job giving the details and explaining everything thoroughly.
Oh wow these videos alleviated so much anxiety! Thank youuu
Didn't cover as much as I thought, but still a very effective video for basic. Clear cut and understandable!
subscribed immediately. You're the best, thank you so much.
Thanks a lot man. I have paid a lot for a Data Science course and the quality of statistics content you deliver is much more higher than them.
Lovely lovely explanation. Amazing! God Bless!
Seriously, one of the most I liked video.... Thanks for this wonderful job...🙇♂️
தமிழ்லயும் இந்த மாதிரி சொல்லிகுடுக்க ஆசிரியர்கள் இருந்தால் நல்லாருக்கும்.....😒😒
Your explanation was really interesting and more understandable... and I got an cristal clear idea about this topic instantly.. Thank you so much 🔥🔥🔥
I was so confused with what the y-axis on the PDF represents. This video helped me a lot. Thanks!
You are the god of simplifying things. Thanks a lot! May you get everything you wish for . And keep helping us this way. :)
you cleared my confusion and i just can't thank you enough!!
I wish i could have a teacher like you in my class..i was revising all the basic concepts and it really helped me. thanks...gonna see the whole playlist..
yeah, he has been really nice in making videos that are easy to understand and even simplifying the hardest concepts
thank god you were there! I was almost halfway through my portions suddenly in book they used PDF achronym dk what they were refering. First few min through your vid my doubt got cleared. thankyou
You helped me understand a 1000x more than my professor ever could. Thank you so much.
Really helpful! appreciate for distinguishing those buzzing term with clear graph
Thanks for the video. I was looking up PDFs to understand Maxwell's velocity distribution & this really helped!
Great videos to help me pick up the basic concepts of statistics! Thank you very much!
Most detailed and explained lecture I have seen . Big ups
oh lord. this video put me on the right track, I suddenly understood so much more. thanks!
I'm so glad I found these videos! I am tasked with implementing some of these techniques in code. Deer in front of headlight situation without much of a mathematics background... Not anymore!!
Oh my God. How you simply teach the topic ,
At one go I understood wholly.
U are brain gem .
Knowledge not shared , is wasted.
Thank you
OMG SUCH AN AMAZING VIDEO!! Thank you so much and please keep making videos! I have just found your channel and these topic seem so easy now!😍
Thank you, Justin, very much for these video series on the distributions. You are my favorite Statistics channel!
Can you, please, make a video on Gumbel (Generalized Extreme Value) distribution?
Your explanation is absolutely perfect!
This was explained better than my masters and its free!! Unbelivable! Thank you
my professor took several hours to explain this & still didn't manage to teach clearly :( you are a hero!!
Thank you! this was so helpful. I have subscribed and will recommend this channel to my peers.
Dude I've paid statistic courses in Udemy and other platform that don't explain nearly as nice, or in the same depth, as you do. Thank you very much.
Crystal clear explanation!
Just the perfect video I was looking for regarding PDF & CDF
Statistics makes so much sense when you explain..thank you! Please could you do a video on Limits especially the Central limit therom?
