Wow! You should do this for a living! Teach stats that is. You have adopted the perfect professorial tactics: take nothing for granted. Keep the explanations simple. Don't use jargon if you're not going to explain it and even then, keep it to a bare minimum. I've seen others posts of yours and they're all equally excellent! Thank you!!
I enjoyed this subject matter only because you explain the definitions and the procedures very clearly and your tone of voice is calm and soothing, unlike other instructors that act and speak with an obnoxious attitude. You are awesome!!!
With all words of gratitude availed : Thank you for your great manners which is the highest radiance of light in your insightful well-devised structural method .
At last!!!! It never occurred to me that there is a difference between the standard Normal curve and the normal curve. The standard deviation thing was driving me crazy! Thank you!!!
I've taken through Calc III (in college), and got an A in that. A few years later, here I am taking Stats. I decided to do it online, because after doing Calc III, Stats would OBVIOUSLY be a piece of cake! ...Wrong. I'm having so much trouble with it, and not having a teacher to talk to is horrible. Then I found your videos and all is well! I'm seriously just watching each video you've made as I go along and learning from those. Thank you so much for making these, and for explaining the concepts so well!!!
So far I've seen that graphs help a lot in understanding stuffs in statistics. it helps us visualise what's there in the distribution. Most of the classroom teachers give pdfs and solve problems using mathematics without telling what is actually happening there. so after watching this and some more videos from other channels, I've learnt that graphical approach is the best approach (at least in statistics).
i'm a homeschooled 10th grader and i'm learning this but since i only see my teacher once a week and i do my work online i am expected to figure it out myself. this video saved my ass
had to watch on another computer mine was giving no sound, althogu i can listen to other youtube video's just fine. im glad i spent the effort to watch, you explain it in such a clear way thank you very much. for some reason i cant get sound from any of your video's, guess ill be watching them on some one else's computer. PS. i tried watching other people explain this and they were not even close to how clear and easy you made this.
Best Stats lecturer ever :D ! Love all your videos its simple and concise as you work the problems with us ^.^ ! Fun :D -Your a awesome lecturer that is not afraid to laugh at his mistakes as well ^.^ which makes it more fun learning from you :D .Thank you,Sir with all my heart
... Dear Sir .... Thanks a lot for your invaluable videos please could you numbering them in sequence to enable me and others to follow the course in sequence ...thanks a gain for your efforts
I'm already challenging someone else on UA-cam for this, but the area under your curve > 1, isn't it? The height at the mean should be only ≈ 0.4 other than that, I like your delivery and presentation. You even put the +1st SD on the inflection point. Thank you. Pretty good for a quick sketch! But does the integral matter? I think so: when Psych students get tests back with a Z-score, an improperly swollen curve exaggerates their rank in the population (as seen from comparing areas left and right of their Z). But the graph is just that: it's supposed to be a picture that reflects the data rather than distorting it. Notice how on the swollen curve we can visually square the length from the origin to SD1 and it fits under the curve. In fact there's room for another such square on the negative x-axis. That means the area is already 2 and climbing, since there's still space above the 2 squares and out down the tails. Without an integral of 1, we are forced to disqualify the curve as a probability distribution. Please plug the SND equation into a graphing calc pgm to see the true curve. You'll see what I mean: they should have called it a cymbal instead of a bell!
clarklambert Well, depends on what you mean by area. When you're talking about the probability, then yes, the area under the curve from -infinity to infinity will always equal 1. Let's say the area under the curve of some distribution from - infinity to positive infinity equals 5 units. If you want the area under the curve to equal some probability though, you can just divide the function by 5 and voila. This is because by convention probabilities are out of 1. You're talking about the probability density function, and the 0.4 does not mean what you think it means. The number on the Y axis is the number that you would multiply the it's corresponding infintesimally small x interval to get the corresponding area under the curve of that infintesimally small x interval, (or probability). Another way of putting it. If you have 5 possible scores on a test, and you had 10 people score a 1 ,15 people score a 2, 20 people score a 3, 15 people score a 4, and 10 people score a 5, the area under the curve on a histogram would be 15+20+30+20+15 = 100. But that's not what a probability density function is, the equivalent would be like this. Instead of the y axis being the "total number of people" who got that score, it would be the amount of people out of 1, or the percentage of people divided by 100. So the probability density function for this would be 0.15 for 1, 0.2 for 2, 0.3 for 3, 0.2 for 4, 0.15 for 5. And the area under the curve would be 1.
Could you explain why in statistical inference one should never standardize a variable according to a sample distribution of the same data and why that would be circular reasoning?

BRUH WHY COULDN'T MY PROFESSOR EXPLAIN IT LIKE THIS?! Thank you.
lmao my also
I learned more from this 5 minute video than I did in my hour and 30 minute class.
Same
Yes same situ
😖
You explained an hour and 45 minutes of statics in about 4 and a half minutes. I love you.
This is the best explanation ever! and your voice is so soothing !
I enjoyed this subject matter only because you explain the definitions and the procedures very clearly and your tone of voice is calm and soothing, unlike other instructors that act and speak with an obnoxious attitude. You are awesome!!!
The world needs more youtube teachers like you. You are not the stats teacher we want, but one we need!
THANK YOU! I'm learning from home and the textbook is all greek to me
Τι εννοείς όλα Ελληνικά φίλε μου haha I learnt Greek and it's an amazing language, I just study every night for 30 minutes for 1 year.
Fast forward 4 years, we are all learning from home.

This is so simple and really loved the way you explained in simplistic terms, thanks so much. I wish my teachers and professors were like you!
With all words of gratitude availed : Thank you for your great manners which is the highest radiance of light in your insightful well-devised structural method .
Beautifully short and to the point without confusion. Thanks for the video
Thank you so much for the videos. I have been struggling with Stats until I found you :)
This is the best explanation i have ever come across.
At last!!!!

the most effective 4 min in youtube
Thanks! You are awesome, your voice did not put me to sleep!
You are brilliant in your simplicity! Thank you thank you thank you!
Thank you! Your explanation is so simple. Hope you are still active on UA-cam.

thx my teacher made it hard for mr to understand but ur explication made it easier
Great Teacher indeed.
great!! much better than listening to my stats teacher
Concise and very very clear! Thanks!
It is clearly explained...do you have more of probability & statistics topics like Gumbel & other probability distributions?
Thank you for explaining it in layman's terms. Great help.
really helped .Thank you for the job.
Thank you soo much Sir, I never concentrated on the 5th and 6th points. Good Info, Thanks once again :)
THANK YOU, my professor was so confusing explaining this
Really wish you are my stats professor!!

soo interesting...very helpful
Omg....Thank you for this!
Hello sir. May I ask if the standard normal distribution and the standard normal curve are the same?
Thank you😀
How is the area of the bell curve 1?
Thank u sir , 😇
best teacher
Could you explain why in statistical inference one should never standardize a variable according to a sample distribution of the same data and why that would be circular reasoning?
does skewness between -0.5 to 0.5 is normally distributed?
nice explanation
So helpful, thanks!
Link to next video??
it does help!!!! thank you so much!!!
Thankyou sir..
Excellent!
thanks
God bless you richly
could you please also tell me the second order differential of gaussian curve
you are great man
Thank you .. thats really helps
🌸
