In this lesson, we will cover what the normal distribution is and why it is useful in statistics. We will solve problems using the normal probability distribution and describe its characteristics..
I bought the statistic course and oh my god every one hour spent watching them is like the best hour of my life this guy knows what he is talking about i cant thank him enough without him i would still be lost and confused god bless you
you are making a great difference in our lives
Thanks a million! At first I was thinking to write down that you have the most suitable voice for teaching. After I saw how much sense everything makes for me I believe that it would have been a shame if you wouldn't have been teaching. Best of luck!
Hats off! I have been browsing through video after video on TH-cam to understand what this means, most professors took a mathematical approach to explain it. You explained it through plain and simple logic - exactly what a non-math student like me needs. Thank you so much.
I never thought it would be easier, your lessons are interesting and recommendable 100%
Thank you for your beautiful clarity. My interest in life is poetry, you bring out the poetry in mathematics. You actually, unlike a lot of renters, make a difference in the world. Bravo!
THE PROFESSOR DESERVES A STANDING APPLAUD
All youtubers are saying the normal distribution is a bell shaped distribution
But no body explains like you with the watermelon example,I understand the normal distribution with the help of that example

I like ur teaching
Thank u Sir
U r the best lecturer
-----
U r awesome
I'm a working professional.
Performing as deputy manager in Morris Garages India.
This guy's videos have helped me understand the concept and crack the interviews.
Thank you sir.
You are awesome.
Love from INDIA
You are making statistics fun and easier to learn. Thanks a lot
Eventually found a video I can understand totally. Thank you! You are way better than many famous professors for me.
It is amuses me the way he served the topic to us . He is make things absolutely clear in head and recommend his lecture to my little brother .
You make learning math easy and fun. Some of the concepts I learned over fifty years ago are coming back, just by watching your videos. Algerbra and statistics for example. Great job.
I love the way you bring the concepts of the subject down to a level that's easy to understand for those who haven't seen them for a while. Another point is the way you will explain concepts learned back in elementary school.
Again, excellent job.
This isn't math
some people are traders and have no business teaching, you sir are a teacher as i finally understand what all this means ,hanxs alot for the time
For all those who do not understand why the area under the curve is 1: the sum of all probabilities for a sample is equal to one. For example if there is a box with blue and green and red balls and the probability of getting the respective colored balls are denoted as P(green), P(red), P(blue). The sum of their probabilities will always be equal to one. i.e. P(green)+P(red)+P(blue) = 1
The only difference between the above example and the watermelon example is that this example is a discrete distribution while the length of the watermelon is a continuous distribution. Hope this helps
Yes that was a question I needed to understand, the onset for that is when you have to understand when the equation asks for the value to be minused from 1 or not, I am still trying to get to that stage. But thanks for the explanation.
Sometimes I refuse to attend 2 hour class and watch 20 mins video and still pass more than others😂😂😂👽☠️
Thanks to your videos I could pass my statistics exams in my engineering studies!
This is the bestttttt channel explaining the concepts of statistics on internet.. thank you sooo sooo muchh 😀😀
This guy never says his name but I've learned SO much from him I LOVE this guy. He's the best teacher there is anywhere.
His name is Jason Gibson he used to work at NASA up until 2009 when he started to make online courses. If you want more in-depth videos you can check out his site and buy his courses.
Thanks ... I agree he is an excellent teacher
Thank you for what you do and doing it so extremely well! You are making a big difference to society!
waoow, you have satisfied my day with normal distribution and the hypothesis test...
Thank you for breaking this concept down in a way that is easily understood. I've learned more from you than lecture, lab, and other youtube videos!!
super sir, well explained. your voice is clear and peasant
"Now I'm not a perfect artist" -every math/science teacher ever
Thank you, brilliant presentation, 👍
I really appreciate your clarity on how you explain. Please do not assume that we know. Every step is important to those of us who do not know a thing about statistics.
Thank you!
i am a tutor at chegg if u have any problem with quiz in statistics i will help u
You are an excellent tutor. Some people are just gifted that way.
you are a legend! such a big help, cant thank you enough
easy and straightforward , I swear i am going to watch your whole probability course as a netflix show
You present in a clear and comprehensive way. Tks a lot
i dont have words to praise you sir....this is magic, after loke wartching 100s of vdos on youtube......finally i got hold of Bell Curve........HATS OFF
im pretty sure lot of people have passed their tests because of this guy
@Jace Ryker you think you did a great job bud?
All 332k of them.

Hi 👋 truism
Ty I think 💭 said she has
This man is AWESOME!!! I wish I'd met him years ago! I love viewing his videos and I truly learn something everytime I view this great teacher. I wish there were a way to ask questions and get answers from him.
Can someone tell me how to design a bell shaped curve using a sample from past winning lotto numbers?
For example, in the Indiana HOOSIER LOTTERY I graphed each of the 5 columns of past winning numbers for the CASH 5 game going back a couple of years.
Let's just look at the first column. The MAX number that won is 28 and of course the min is 1. So, the range is 27.
Wouldn't it be easier to analyze each column separately like that instead of trying to figure out the winning picks of all 6 numbers as a whole? (CASH 5 has numbers)
How can I make a bell shaped curve with 1/28th increments with, say, 14 as the mean, and how do I interpret it?
Also, How does one make predictions from this?
I've been using Excel 2013 and my TI-83 calculator to calculate mean, trend, median, mode, max, min, range, q1, q3, , variance, st.dev, skew, and kurtosis, of each column of numbers ... now I'm trying to learn how to calculate Z scores and apply this info to making predictions for each column of numbers separately.
Since they didn't even have computers and calculators when I was in high school, (I remember when out high school bought their first electric typewriter), I watched TH-cam VIDS to teach me how to use the Ti 83 calculator and EXCEL 2013 to do statistics. I need some help with the afore mentioned. ident2twin@aol.com
Took Statistics 28 years ago from a guy just like this🙏 warned folks back then that 80% of mathematics is studying the college schedule and researching your instructors! I got a 3.9 in that class and the folks in the other class averaged a 2.4 from the PowerPoint professor👍🏾
Hey There..…! I Am From Bangladesh... And I Would Like To Say That This Video nd The Professor Is Superb... I Mean He Delivers The Speech In Such a Tremendous Way....! Keep It Up Sir...! ❤ These Help us a lot to study more nd to understand the Statistics in a Beautiful Way......! ❤❤
I am from Bangladesh too.. Where are u studying now?
Very clearly taught. So appreciate you!
You are much better at explaining than my teacher, because he wants us to understand not just do procedures.
I love watching your video.
Thank you so much, I am in mid forties and I am just getting a hang of these concept because my job now requires that I apply them. Just know that you are helping strangers out there.
I'm in my mid 40's getting a bachelors in statistics lol...
My job change requires it.
that's a fantastic explanation...
Awesome explanation. Hats off..!
Love it, this is great, THANK YOU for your videos.
Perfectly explained .. Thank you
Pretty simpler and clear. Very good!
Thank you for your explanations! The way you explain statistics helps me to separate concepts. I appreciate your videos greatly!
You're very welcome!
@@MathAndScience 🙏😇🙏😇
This guy is a genius when it comes to explaining. Good work comrade.
i am a tutor at chegg if u have any problem with quiz in statistics i will help u
God bless you Sir you've eased my pressure to learn these topics under statistics
Simply the best.
such clarity. thank you.
Needless to say, No one could explain better than you in this youtube world !!
Aw professor you are so brave with your explanations. The mean is from 20 going down to the right side of the length. Is increasing sir. The drawing of that shape is population pprobility. distributions up to the top of the drawing is the area. When the shap is going to the left side is decreasing to 10 and so forth. My God this professor is great with his sound explanations. Those formular is good but it some how difficult to work with your hands. Is good to plot the work in a calculators sir. I dont do calculus. I did algeriba . I love to work on maths so i will put all my attentions to work on this and understand correctly. Perfect explanations sir. Sound video
I am so happy I found you, about to binge - Thanks so much!

It's null hypothesis and alt hypothesis. The z score that has rejected the null or has failed to reject the null. Valid or invalid
Brilliantly Explained, Helped me to understand easily. Thanks
You are amazing. Thank you 😊
Please help: 4. Bone density can be measured using a DEXA test. Bone density for a 25-year-old woman is normally-distributed with a mean of 956 g/cm2 and a standard deviation of 5.52 g/cm2. Let X be the bone density of a randomly selected 25-year-old woman in g/cm2.
My great Prof!!!❤️❤️❤️
I have enjoyed, thank you. From malawi
14:54 🧐😵 I’m like damn I have to cram this formula.
Excellent.
What is the difference between normal distribution and normal probability distribution? Or are they same thing and can be used interchangeably
I'm taking a state test on 5,6,7,8,and 9 grade math. Do you have any DVD's that teach those grades?
Text book jargon explained in a way that anyone can understand it. Awesome! Why couldn't they do it this way in the first place??? (I'm getting very annoyed with the way they generally 'teach' math and statistics! No wonder people hate it.)
thank you.. this was really helpful..
So happy you liked it!
