the fact that he added practice questions give me mad respect for this mans work
Thank you so much bro
Agree!
It's very easy to follow! Thanks for simplifying the process.

Videos like this are the reason I love youtube. Learn much more than attending a lecture for 3 hours and still not learning anything.
Thank you for your comment :) I wish you the best with the rest of your studies!
Exactly!! So grateful for these tutors!
Couldn’t agree more!
I am a professor of engineering teaching my daughter statistics and this is probably the best video I have seen on introducing the normal distribution. Kudos.
95% of viewers approve of this. The other 5% are just mean.
Incorrect. Its not "the other 5% are mean". Its the other 4.7% are just mean
@@Kennymac8251
Incorrect. Its not "the other 4.7% are mean". It's the other ~1% are just mean.
and some folks are simply average.
We call them, outliers.
i think you where one standard deviation off with your guess ;)
but hey .. at least far less than 5% are mean :D
Jeez, I'm studying at one of the most prestigious business schools in my country, and never have I heard an explanation of the normal distribution and the the 68-95-99.7 % rule, that is so simple and easy to grasp.
Just, wow. Great job, this is going into my Statistics playlist, and I'm liking it right now.
I was about to comment the same thing hahaha, thumbs up!
You didn’t get this at a prestigious business school? Yikes. What school, may I ask ? I learned this in undergrad- at a second rate college
@@recipehacker9752 He mean that he never follow the lectures because he always play his handpone during the lesson.
Sometimes B school professors can make things too complicated.
bruh ur profile pic made me rub my screen..
Although I know most of this stuff, I was astonished by the way the graphics had added detail to the presentation. Excellent presentation.
Thank you so much, I appreciate that!
Same here
@@Simplelearningpro Par Excellence stuff, excellent work and super excellence team work. Could you share which software is used to make this presentation. I would like to learn this.
@@Simplelearningpro would you like to inform us what software to use to design the motioin graphics, thankyou
Exactly. It makes everything more clear
The way you explained everything was in a very organized matter. Thank you!!
The brilliance in the renditions is overwhelming. Thank you!
Creating Curiosity and interest in the students is not a child's play, That is just what you did !😇 Thank you ❤
I think I learned more out of this video, than I did in my college Sadistics class 40 years ago
sadistics...good one
Me too
Same here
It’s SAD and it’s SADistic. Great one!!
Hell correct!!
Precise, clean, ordered, neat and the graphic representation just can't be more dynamic or easier to grasp. BIG THANK YOU!
A big thank you as well for leaving a comment! I appreciate it :)
Excellent! Precisely done along with easy, user-friendly, easy for one to understand, up to the mark, and rank beautiful infographic implementation with a great sound knowledge of the subject.
Thanks! for such a nice video!
❤
This really helped me understand the normal deviation rule. Thank you so much, this was very useful and a great way of simplifying the rule for easier understanding.
Thank you! I have such a greater understanding of standard deviation because of the visuals and I can actually get the 68-95-97.7 rule. The questions at the end also helped me understand better.
This is hands down the best format for delivering information that I've come across
Best explanation of normal distribution ever. 68-95-99.7 rule. where have you been all my life. Thank you very much
Loved the simplicity in explanation!!!
Perfect way of teaching and presenting. Thank you.
You made my day so easy. From yesterday I was sitting with one page from Andy Filed’s book to understand this. But ended up getting frustrated and sad as the explanation was going to unnecessary stuff. Came across this video, just made me to understand the concept so easily. The question at the end is gold. Please post more videos! Thank you so much.
❤ Nobody else shows the 68-95-99.7 rule and its been bugging me. Thanks for including that.
This is the most comprehensive explanation.
This is legit premium content for free on RUclips, tomorrow;s my exam and your videos helps a lot! More animations and interactive it got, more impressed I was from your content delivery
I'm glad I was able to help! Hope your exam went well, and good luck with the rest of your studies!
Sir you are the teacher we need in our classes.
You make the best educational videos. LOVE IT !!! CLEAR and CREATIVE
The use of diagrams and graphs makes this video really easy to follow.
I have an exam in an hour and this helped everything click right away. Thank you so much!
I hope your exam went well :)
so..... how did it go?
WHAT AN AMAZING EXPLANATION BRO,U HAVE EXPLAINED ALMOST ALL UNDERLYING CONCEPTS RELATED TO THE TOPIC...KEEP POSTING WE WILL SHARE AND SUPPORT
It is much easier to say "bell curve" than "normal distribution". He said it so many times the video is 25 seconds longer than if he' would've said bell curve. :)
What? I can’t hear you 👂
This video was more thoughtfully laid out than the curriculum at my college. I just learned in 5 minutes what my stats professor has been trying to explain (unsuccessfully) for weeks... I may pass this class now haha. Thank you so much!!!
Clearly & concisely taught. Thank you. I struggled with this 50 years ago, got it eventually but I wish I had your help back then.
Hello from India🇮🇳!! I was new to statistics & was studying statistics topic like ANOVA & chi - square.. However these symbols were not making sense to me, randomly watched this RUclips video.. & goshhh.. This was such a eye opener... Easily explained the basics with simple animation.. Now it is all cleared. Thank you so much ❤
Perfect explanation for my Statistical Quality Control class. Greetings from Universidade Federal do Tocantins (Brazil).
Greetings! I love Brazil! Thank you for commenting!
I had three fantastic QBA courses (quantitative business analysis, statistics for business majors) at Penn State in 1976 - 1977. This terrific video brings it all back, Ty!
Dude i’m in college and none of the 5 semesters explain the concept like this. You make it much more simpler for people to understand. And my major is STATISTICS CAN YOU BELIEVE I DONT UNDERSTAND ANY OF THE FKING CONCEPT until i saw this video. You saved my life. Thank you so much
This is the best explanation I have found across all platforms, it will become so easy for the people who get confused with complex problems while solving the questions.
Thank you, your comment means a lot to me :)
I don't think it was an explanation. It was a presentation.
This is amazing, your videos should be compulsory viewing for statistics teachers and lecturers!
Congrats my friend, simple, clean and direct! Loved it
Amazing! Thank you. These were one of my most efficient 8 Mins in my life
Thank you very much. I benefited from this 9 minutes video more than the $1500 college class.
This is just amazing! It is the best, I mean best, explanation I have ever had on the topic since I started postgraduate business school! Thank you so, soooooo much!
You're welcome! Thank you for watching and leaving a comment. I appreciate it :)
This video helped a LOT! I never could understand the Normal Distribution curve or the Z-scores in general, and no matter how much I asked for help I always ended up more confused or lost after two steps. This video gave me a simple explanation and even helped me understand the 68-95-99.7 rule which I never knew even existed at all. This was very helpful in my understanding on the Normal Curve/Distribution so thank you guys for this!
Excellent and lucidly explained- JUST AS YOUR ENTITY is Named
This video crystallized what I've been trying to understand all semester, thank you soooo much! MATH 1342 Stats
Cynthia McAlister Hi, Cynthia. This is your stats professor. Please see me after class. I hear you’ve been confused all semester :)
Guys this video amazinnnnggg, thank you so much 🙏🏼 🌸
Hope you upload a whole tutorials in the same way ❤️❤️❤️❤️
Many more videos coming soon! :) Thanks for watching!
Gosh, when I first saw the parameter vs. statistic distinction at the beginning, I was sold. First time it became clear in 10 years of learning. Thanks for helping out so many of us here!
Thank you for the comment Amanda, I really appreciate it :) good luck with the rest of your learning!
I haven’t even gotten to the end and I have to say this is the greatest instructional video I’ve seen in my life. Even though I studied this stuff your presentation has given me new insight. Wow. You’re doing what Feynman did so well. Thank you so much for this video.
Thank you so much, that means a lot to me!
I’m sharing this to my entire cohort. Hopes it help !
Thank you so much!
i have my first ap stats exam tomorrow, so this was very helpful thank you!!
Hope it goes well!
Amazing.. The Easiest and Shortest Video I came across in the Web for Understanding Normal Distribution Curve. Thank you
Keep up the good work. I love it. The very best videos on RUclips.
Keeping going bro!
Thank you! I will do my best!
OMGGG FINALLY I FOUND A GOOD AND SIMPLE VIDEO AFTER 3 HOURS ;(((( THANK YOU SO MUVH THAT YOU EXIST THANKS AGAINN -^-
Thank you so much! Glad I could help!
Thank you very much for making my learning easy. Your lectures are simple and sweet. Not complicated at all!
Amazing! Thank you for inserting the practice questions. Without them, I think my learning would be compromised!
great explanation about normal distribution. I will use this to my class. thank you very much :-)
You're welcome! I hope it helps out your class :)
4:23 mistake: the value used at the end of that notation is supposed to be the variance (σ²) not standard deviation.
Note: that I studied normal distribution in Australia.
I agree it should be variance, σ². Overall, it is a very nice video, well illustrated and narrated; it is a concise overview. I especially like the definitions at the beginning to help us understand the terms statistic and parameter.
@Donald Trump Good question. In this video an important idea is standard deviation; however, in further studies variance is important. It is used not only to derive the function for the normal curve, but can be used to calculate endpoints for confidence intervals and critical regions.
The notation used in the video is a standard form, which means if it is not presented accurately it perpetuates errors. Using your Pythagorean example, a common error with students is that they do not take the square root after they square and sum the leg terms, meaning their formula is a^2 + b^2 = c. The square is lost in their thinking and so they have an error in their solution.
Again, it is a nice video. It does well to present the real ideas they are trying to cover. Discussing a minor error without losing the rest of the topic is important too.
Best video on this topic so far. Thank you.
Great video! The graphics made it very easy to understand the Normal Distribution/68-95-99.7 rule. I extremely liked the questions at the end, which was greatly explained and made it impossible not to understand. Thank you!
Your vedios are the best one's in youtube and it will going to be the top in future
I can't quit without saying thanks to you...
You're welcome!
This is a great explanation of the normal distribution curve.
This is such an amazing way of teaching ... I literally didn't get bored watching this :)
hey! Could you please prepare a video about "statistically important values" when P
Statistically important values are ones that are usually determined by the statistician or researcher. In general, a P value of 5% or lower is considered to be statistically significant. If something is statistically significant, it usually means that the relationship between two variables is caused by something other than chance. And based on that outcome, you can accept or reject the null hypothesis. I will be making a video about this topic in the future, but unfortunately not any time soon. I hope that helps! Good luck with your studies, sebo!
Dear Sebo statistically significant means values are statistically different but that doesn't mean it is practically significant..

And also I m confuse on various charts for continuous and discrete data
OMG, the best Stats lecture I've ever had. Congratulations!
Thank you!
I'm currently taking the Six Sigma Green Belt certification course and I watch these videos to support my learning. Having a different perspective and various teaching styles helps me a lot to see the same information from different perspectives. Thank you!
Glad I could help! Thank you for the comment!
ѵҽɾվ հҽӏթƒմӏ 💐
Yo've summarized my collage degree!!Hehehe...
what a poorly thought college degree
you are part of 5% mean...
@@trotsky5810 u got me, nice
One of the best tutorial I have came across. Bravo, you doing a wonderful job.
The practice problems combined with the lesson made everything click for me. Thx!
what the sigma 🤨🤨
Bejezuz christ .... how the hell did I end up here from watching videos on making various types of omelette?
Hehe your comment made me laugh! Hope you have an awesome holiday, and an awesome omelette!
95% of the recommendations would be related to the video you're watching. The other 4.7% is arbitrary.
I used a lot of textbooks to understand the Normal distribution concept but this video summarized it all. Awesome
Thank you for your comment Anees Javeed, good luck with your studies!
This is the best explanatory video i have ever seen
Me when I m(ew)u so I become sigma 🤫🧏♂️
JUST WOWWW ! this is it !!! beeeen trying since many months to get hold onto this topic from 30 mins+ lecture videos but couldn't understand any of it, came across this one and it made my concepts crystal clear. Thanks Alotttt 👌
Brilliant piece of lecturer. Now I'm fundamentally clear
This is by far the best and simplest explanation I've come across for the concept of normal distribution. Thank you so much for putting in so much effort.
Thank you so much, I work really hard on my videos so seeing comments like these make me smile! I wish you the best with the rest of your learning! :)
Спасибище тебе дружище!!! Very appreciated that sir
Thank you for this! I have a much clearer grasp of population parameters and what it means when there's a Bell curve. I'm glad you don't rush through the practice questions either!
Thank you for watching and commenting!
you are the real lifesaver bro... this what I'll call the effective way of learning.
Absolutely elite teaching experience
I just saved myself so much time watching this video. Thank you for the great work my guy
wow , this video is juts wat I needed .aamzing way of explaining with graphics.its so much more simpler and crisp compared to long boring videos.THANK YOU
This is the clearest explanation I have ever watched on normal distribution. Thanks much simple learning pro.
Great video! The graphics made it very clear for anyone studying Normal Distribution/68-95-99.7 rule. I also greatly appreciate the practice questions in the end, which had explanations that made it almost impossible not to understand. Thank you!
Thank you so much!
made my life so easy with this lecture
Very visually pleasing and interactive. I enjoyed learning through this presentation.
So beautifully and intuitively explained! I believe this is the first video I have watched from this channel, but I know I'll be exploring more and sharing the content :)
Thank you. Excellent presentation of the normal distribution curve.
Perfect. Simply Perfect. Thanks alot.
Thank you for simplifying this for us!! Love you ❤
I have watched several videos to figure out the 68, 95, 99.7 rule and this video has explained it the best!!
Very clear and easy to understand. thank you so much...
Loved the explanation. the best video for sure on easy explanation about the bell curve. HIGHLY RECOMMENDED.
I cant describe how much your videos have helped me to understand these topics. Thank you so much for the effort you put into these.
No problem! Thank you for your comment!
A comprehensive Lecture...
Love the way how complex ideas were simply explained....keep it up
what a video! thanks mate. big shout out from brazil!
Awesome! with you, i understand 99.7% of the content. With others, i understand at most 68%. Thanks.
Thank you so much to the team at Simple Learning. Great resource
never find explanation clearer than this. thank you!
*I never find any explanations more clear than this. Thank you! Please work on your english lol
Such an amazing explanation. The visualizations and animations are so smooth that you get the concept without much effort.
