In this lesson, you'll learn about the concept of variance in statistics. We'll discuss how variance is derived and what the equations of variance means. We will also cover how variance is very closely related to standard deviation in statistics..
Oh my god you are so clear! Your 17 min video is more useful than the last month of lectures for data analytics at the university... Keep up the good work! :)

SO BLOOMIN TRUE!
I wish i had a teacher for statistics like this guy. (i had a stupid one hated stats) but had to work with them and learned them myself.. you rock! excellent presentation
Nova Cane ditto
i had the most stupid teacher you can even imagine in statistics.
The same to me. I wish he could be my teacher. It's my first time to understand variance in my entire life
Same here...
Yo bro.....same situation was there
Looked at several tutorials; this by far is the most direct approach. Thank you.

raashid khan hi
Hello
Are you good at stats?
I'm familiar with this concept, but this by far the clearest and best explanation I've encountered. Respect!
I love this tutor, this is the way to teach students, he makes it very basic and teaches it in an applied way. I wished I had known him earlier
I can't express how much I love the way you teach. it's so interesting and easy to understand. thank you so much for your initiative. I am a student of mass communication, and for my PhD program I need to learn statistics, and it seemed so pathetic to me. your lessons made me feel like statistics is as interesting as journalism itself. thanks you is a small world. but I mean it.
Thank you! Thank you! Thank you!
5 statistics books, about ten videos, and a college course, and none explains what a variance actually is in such simple description

Absolutely incredible. You are a true legend, sir. Honestly, one of the best teachers out there and extremely patient in arriving at the answer with a logical and intuitive approach. Thanks so much
I've had different statistics courses throughout my degree that I've kind of just been winging. For the first time, I actually understand this concept! You're an amazing teacher.
This is explained so well, especially for a beginner, thank you!
Finally! I now thoroughly understand variance, thank you! I wish all my professors would speak this clearly when teaching about complicated subjects.
Your explanation is so incredible, l tried other videos to understand stat terms was so difficult but with yours now is very clear. Many thanks!
What a great explanation! Thank you a lot, Professor. The world needs more instructors like you!
Sir, this was a very clear and pure way to understand variance. I am very grateful to realize this. I am studying econometrics and i could never really fundamentally wrap my head around what the variance truly meant. It's easy to calculate, but for me to intuitively understand what the variance is at its core and the importance of this for statistics... is because of you. thank you
Sometimes I just get frustrated on our education system for just running behind marks and not making the students understand any of the stuff .Hope one day my country will also have great teachers like you who makes the student know clearly what they are learning. Thanks a lot sir,huge love and respect from India.
Thank you for breaking this equation down and making it so easy to understand.
This is immensely helpful. Thank you so very much for sharing!
You have to watch 2 or 3 times, to appreciate.
Very detailed, thumbs up.
bless you kind man!!! it has helped me tremendously. y cant my stats teacher teach like this!
nice
Thank you for this very simple and easy to follow explanation
amazing description in everything, actually I am shocked by how this teacher consider himself as a simple student to not make explanations even a little bit complicated..thank you so much, teacher.
Excellent video! The concept was extensively and clearly taught. Thank you so much!
I like you. You make this easier to understand. Quick questions-is there a list I can find on which order to watch the stats videos?
Hi.Thanks alot for your quest to make life with stats bearable for people like me.I am forever grateful to you. i wish i listened to the videos at the beginning of the semester would have done an 'A'. How can i get the complete stats video by the same person with topics like Correlation ,regression,probability ,hypothesis.mean.medial,mode,measures of dispersion ie interquartile range, relative measures of dispersion ,coefficient of correlation,standardization ,sampling proportion etc Keep it up Sir. You are a gifted teacher.
To "simply" do your work as it should be done, is already helping other people. And you do that beautifully, humbly and very effectively! God bless you for that! You are a truly master and professor! Thank you so very much!
Thank you so much!! I've been racking my brain trying to figure this out for my college statistics course and you made it much easier to understand. Thank you for taking the time to help! :)

Extremely good teaching, captivating and simple explanation.
Wow, you explained this very well. I read the book, however, I wasn't able to understand it. I now understand it after watching this video, thank you.
by far the best ever, online AND in reality. I am purchasing the rest of the courses right away. its priceless.
I wish most professors are THIS elaborate! I needed classes where they explain why we use the formula, what it gets for us, and basically the significance of it all. Few of the professors I had in Stats were going straight for the formula, and they didn't really explain the whats, whys and hows. I wish he was my Stat teacher, maybe I have fallen in love with Stats from then on!
I thought I was innately bad at Math until I came across educators like yourself who really care about learning as opposed to getting through a curriculum. Thank you for this.
I've been trying to understand what variance was actually for all year and you've explained it in 17 minutes. Thank you
Clear and precise! Thank You!!!
Almost all other stats videos never really explained the concepts but this guy teaches us in a way that it really gets sinked in deep in our minds. dam well done Sir.
Great thank you!
Thank you, I have always known how to calculate variance, however, your video helped me gain an intuitive grasp of variance.
You are awesome man! Thanks to you I understood what I was struggling to understand a while in class. Thank you so much.
My statistic course is completely online. Finding you tube is my lifeline. Its a complete statistics course in 5 weeks. This video is super helpful
I wish I would have found this channel before, such clear explanation that the concept would get ingrained in your brain, hats off sir!
There should be an award for making a 17 minute math video feel like it was over before it started. This guy understands how to teach.
Thanks so much!
Man you're great! I finally understood a concept that it was foggy for me, now it is cristal clear. Thank you!
A very clear and well-paced explanation. Thankyou.
Perfect explanation!!! Love U ! This video is super helpful !
This channel has been so helpful to me, at the age of 36 and jumping into the local University, i feel like i need as much help as possible and your the most helpful person online. thank you so much.
Agreed, at 50 I jumped back into the University environment, and I wish all instructors had this guys skills at breaking down a problem and explaining it thoroughly. I often feel as if I am teaching myself, and have done so for the last 2 years. However, in the process I have learned even more.
I really find this video very helpful because professor try to explain the concept from perspective of a know-nothing student instead of giving hard terms. Respect a lot!
You, sir, are a brilliant teacher,thank you.
Your explanations are crystal clear. Your explanations are easy to follow. I wish I had you for my statistics lecturer at the university. Thank you Sir!
The simplicity of your explanation makes this topic very understandable in one go!
Thank you very much I was looking for an explanation why there is a square in the variance formula
You make it look so easy. My stat teacher spent an hour explaining this concept yet I couldn't understand. Thank you so much.
you have no idea how much you've helped me! Always grateful to you !
That was extremely helpful. You explained it from the fundamental concept and now I know the definition of variance. Thank you.
Mister, you are a teacher everyone is wishing for. Thank you.
hello from the year 2019. Love this, came here for clarification in my studies - doing Intro to Biostats this is great. Thank you

You bring it out clearly that teaching is a talent , you have got to be my best teacher for statistics from today and onwards, thank you so very much 14:08
Omg, this tutor is EXCELLENT! SO well explained. Thanks !
Amazing explanation. Thank you so much!
I simply like your way of explanation.. Great job. Salute you.
Lifesaver for my statistics topic, more than happy to purchase your full version at your website. The lecturer at my Uni just assumes us know what these concepts mean, and rush right into SPSS, but really, we need to understand why. BIG THANK YOU!!!
Excellent video! I was not into statistics when I was in college, but somehow the way you explained this made a lot of sense. Thank you
Thank you for explanation, so simple to get the logic , would like to see more videos from you
You're very good at explaining statistics in a simple way! Please continue! :D
I love the way you teach. You just cleared the doubt which is rolling in my mind for ages in a few munites 😍👍
Your lucid explanation on variance helped me out a lot. Thank you very much!
Fabulous content and a simple teaching method! Thank you!
This is the best explanation I have seen. Finally a teacher who understands that students need to feel the concept in their guts!
I'm a psychology student and you are my hero! cause our teacher doesn't explain to us what the words like variance and SD we use are he says the spss will do all calculations. Well, I want to understand the logic behind at least.
This teacher is a genius. He explained it so clearly that even in sleep I can explain what variance is. He directly persist his teachings in first brain.
You bring it out clearly that teaching is a talent , you have got to be my best teacher for statistics from today and onwards, thank you so very much
Dear Jason, thank you so much for this fantastic series on Statistics. I will purchase every single volume you put out on statistics. Everyone out there should recognize that Statistics and Data is the new oil of the 21st Century!
Amazing clarity. I learned this math in the early 1980s, studying for my Land Surveyor's license. I was sitting here trying to remember the math, and it occurred to me to look on CZcams. Now I remember the unknown variables left for me in the field, by incompetent forbears, data points that were suspect just by virtue of who established them. I ended up co writing the license exam for a couple of years. I still have Hewlett-Packard RPN nightmares. So many people know how, but they don't know why. Thanks for being a great teacher. Maybe now I can penetrate my "great cloud of unknowing".
You are extremely good at explaining these concepts i want to know if you have done videos on ECM or VECM?
I have learnt Statics in College and Other courses but now I have have actually got a clear understanding for it. the best explanation.
You have great teaching skills man. Keep up the good work!
You are just GREAT! Thank you for such an amazing lecture.
This helped out with an upper-level biopsych course covering the stats of genetic heritability. Thank you!
This is BY FAR the best explanation I've heard yet. Thank you.
Thank you very much! This lesson help-me understand this topic.
This was very informative; I am in a statistics class this semester, and I actually understood what he was explaining.
This man made me love statistic this trim in school. I couldn't have gotten a better explanation than this. thank you sir
This was so helpful, thank you!
Thank you ! very nice explained !
Outstanding! O LOVE the way you explained the logic and rationale, and not just push for memorization of formulas. I am in my FIFTIES re-learning statistics for my Masters and forgot most of the fundamentals though I use statistics very day. I hated math in high school because I preferred to understand and the teaching style was flash cards for math! Zoinks. Any way, i appreciate you. 1000 thanks!
Please accept my gratitude 🙏 I've been browsing the internet for 20mins. just to understand what variance is. Now i finally get it because of you 🤧 Thank you so much Teacher 😇
Very clearly explained, very detailed. Two thumbs up, can't do better than this. Thanks a lot !!
Extremely helpful! Thank you!
Amazing guy! Teachers should learn from this expert.
Thank you so much for this explanation. This is the easiest / best explanation of variance and deviation. One question that might be stupid: can't we take the absolute value instead of squaring it? like Abs(7-5) + Abs(2-5)
I am grateful !!! You have a perfect way of getting through to students !
Amazing teacher! can't be any clearer than this. thank you so much. it is a mega help
Million thanks from who study German language but take statistics lecture too.
I speak Korean and your explanation is so clear that even I can understand very well. Thanks again for the lessons.
this teacher is perfect thank you for this clear info
Thanks a lot for the video, really well explained!! Greets from Madrid, Spain
Simple and very clear explanation. Thank you !!!
nice explanation. clears out a few obscure angles of the concept. thank you!
One of the best explanation I've seen so far. Awesome! One question though, what if modulus/ absolute value operation is applied instead of squaring to get the positive value from the numerator?
I've wondered the same thing for ages. The teacher in this video czcams.com/video/eZB1TdtO7zQ/video.html says it's ok to absolute values, but these used to be harder to program into a calculator, so they went for squaring instead.
Your video is really helpful for me. Thank you so much 😍 Such a great lecturer 🧡
This was very helpful. Thank you very much sir!
wonderful presentation, simply you just pour the information in my brain, very talented
Thank you! Thoroughly explained!
Thank you! I needed THIS kind of explanation. My mind doesn't just memorize formulas!!
