You explained in 6 minutes what my college professor failed to teach in 2 weeks. Thank you so much!!!! I have a test on this next week and I was so lost. I spent three hours on a homework assignment because I didn't understand their wording and now I get it perfectly!!! Thank you!!
i've been out of school for over a decade but recently returned to pursue an MBA. I literally learned more in 10 minutes than I did in my class last week. Thank you.
@@maxwong4918 if i could pay attention to this video, his way of teaching and understand the concept then why do you think I didn't pay attention to my professor 😂😂 anyways think as u like im glad i cleared my exams coz this guy I'll always be thankful 😊
For programmers (Python): # sd_list = [3,5,7] top_row = [(x - mean(sd_list))**2 for x in sd_list] final_equasion = math.sqrt(sum(top_row) / 3) Amazing video, again and again! Thank you so much TOCT!
here's a cool python program I made for this: import numpy from math import sqrt heights = [175, 180, 190] new_heights = [] x = len(heights) z = numpy.mean(heights) for i in heights: y = i - z y = y**2 new_heights.append(y) for i in range(x): e = new_heights[i] / x new_heights[i] = e std_dev = sqrt(sum(new_heights)) print(std_dev)
i cant count on both of my hands how many times i watch your videos for help. In 9th grade from alegebra, chemistry, and alegrbra 2 to statistics first year in college, you helped me so much you dont understand
yup, this guy has been one of the best tutor I've got. his voice is nice that makes me calm when it comes to math and the explanations are so easy to understand.
I just got mad watching this video cuz I’ve been in stats for 8 weeks and haven’t understood SHIT. But I come to this 10 minute video and everything is clicking and making sense 😭😭PLS KEEP MAKING THESE VIDEOS
I sometimes did not catch up with some of my topics but coming across this channel saves me huge amount of time and he always make this topic much easier and interesting. You are the best. Thankyou
Tysm for your content! Thanks to you I scored a 72% on my statistics test! I usually get really bad grades on my math (between 25% and 46%) this is the first time I've ever gotten this good on math this semester. Really thank you
Dang this is such a simple explaination of SD and Variance! I wish he went over practical examples like how this relates to reading statistical research papers! But his channel alone is the main reason I'm doing well in school!
I love you so much man, you’ve single handedly saved my ass when it comes to statistics. (I’m disastrously bad at maths so seriously, thank you so much)
Thank you sir for showing me what the Sigma symbol represents. It appeared scary at first glance but that short explanation was all I need to use this formula with confidence.
If you’re preparing for an exam or test and are here you gots this and also these videos help so if you’re looking for feedback in the comments here is it
here's a python program for standard deviation import numpy from math import sqrt heights = [175, 180, 190] new_heights = [] x = len(heights) z = numpy.mean(heights) for i in heights: y = i - z y = y**2 new_heights.append(y) for i in range(x): e = new_heights[i] / x new_heights[i] = e std_dev = sqrt(sum(new_heights)) print(std_dev)
dude, i thank you so much sir, once again u saved me in my exam, i only have 2 problems wrong and its all because of arrangement i kinda rushed answering my exam, but still got highest, thanks
I see that you've understood everything without a problem, would you mind to give me some extra easy examples? You dont have to explain it in word, just example of set of numbers and the actual computation? Please i beg of you 😢
Quick question, why is the standard deviation calculation you made for 3,5,7 not over n-1? I thought that 3,5,7 was a sample of the population 3,4,5,6,7. Just asking for clarification. I appreciate your channel it really helps me learn. Especially when I don't understand my professor, so thank you for your work.
Hi Michael, I'd been struggling with the very same question personally for quite some time until I found the following video explanation and it just elevated my whole understanding of this concept to another level. Go ahead and give it a watch, I bet this would be a super productive one. Do let me know if this helps, Cheers! th-cam.com/video/ANsVodOu1Tg/w-d-xo.html
I love how I watched this video back in Yr10-12, thinking that I won't ever need it again, while laughing at ppl in comments that are using this video as a guide in collage and uni Now in second yr of uni, im back to here again cuz I forgot every shit I learnt from my past, and i finally understood why there r so many ppl in here. my professor sucked at explaining the concepts

SAME!
This man is phenomenal! He’s methodical and patient in his teaching. I learned so much from his video.
I come to this channel for everything I don't understand from my University professors
Same here😂😂
Me too 😂😂😂😂
University? I’m learning this in grade 10 yeah buddy your probably in the American school system that’s why
@@alessandrozito7047 statistics isn’t mandatory in the US but you CAN take it and higher in our high schools.

dude this account legit saved my life
This guy helped in Differential calc, then integral calc, then stats, now in GIS courses 🤝
A big thanks to you, this really really helps alot, i understand this lecture alot more than my Math teacher...
this guy deserves everything
thanks for your explanations! you've made online statistics so much easier to learn!
you're an amazing teacher and I've used your videos for all my math classes. I wish you would teach teachers how to teach. Thank you
the way u said sigma, made my day🥰🥰🥰
i have exams this upcoming week, and you teach me better than my lect
Thank you for detailed explanation , your video is always the best. Your are the reason I understand and pass my math classes.
I always find his videos helpful. Thank you so much
This helped me several years ago and now I’m workong and using this in analysis. thank you
Thank you bro, missed 2 weeks of class and this is saving me.
You're so Generalist to explain about all science disciplines briefly
First of all, I love his voice but he helps me understand.
OMG...this video was so helpful...the stress all long gone...thankyou very much..
ha ha i understand more from you than from my teachers explaining in my native language. thanks, man! you re awsome!
Tysm l learn everything from you and lve been the honor of our class by the help of your vids
I love you so much man, you’ve single handedly saved my ass when it comes to statistics. (I’m disastrously bad at maths so seriously, thank you so much)
My favorite math youtuber
seriously thank you so much, all my professor did was the way to find standard deviation is just do this equation here .
You are way better than my ap stats teacher 😢😢
You just saved my life thank you so much!!!! I have a midterm, and without this video I would of failed lmfao.
You have a good method of delivering lectures
Thanks a lot, super concise and clear, you're a blessing man.
This Guy is the Hope of mine in whatever mathematics challenge i face,A big Shout out to you Sir
i finally know how to do math, im so grateful for your account TT
Thank you so much❤ this literally saved me from my exam this week
Thank you sir for showing me what the Sigma symbol represents. It appeared scary at first glance but that short explanation was all I need to use this formula with confidence.
Well and simply explain, My best online tutor.
If you’re preparing for an exam or test and are here you gots this and also these videos help so if you’re looking for feedback in the comments here is it
Thank you professor, currently busy witha an assignment.
He is way more better than my professor .
Hello, when you are solving standard deviation, I don't see the part in the formula where we use (n-1). It's sqrt8/3 at the 6:00 mark in the video?
I believe it's Because We are using the Population instead of a sample
here's a python program for standard deviation
import numpy
from math import sqrt
heights = [175, 180, 190]
new_heights = []
x = len(heights)
z = numpy.mean(heights)
for i in heights:
y = i - z
y = y**2
new_heights.append(y)
for i in range(x):
e = new_heights[i] / x
new_heights[i] = e
std_dev = sqrt(sum(new_heights))
print(std_dev)
Man! you are G.O.A.T👏
thank you very much you have no idea how much you are helping me
Thank you. You helped me get more statistics homework in on time.
I like the way you simplify it. Thank you.
this guy made standard deviation so simple but my teacher in school gave me a long winded complex explanation I did not understand
You have save me so many times!!! Thank you!
you explained this wayyyy better than my teacher. im finally gonna do good on my retest. thank you so much sir
dude, i thank you so much sir, once again u saved me in my exam, i only have 2 problems wrong and its all because of arrangement i kinda rushed answering my exam, but still got highest, thanks
I love this man, but the ads come right when I’m making a break through and then I lose focus
Your voice is so calming I love it I wonder what you look like in life)
Thank so much my teacher didn't explain this topic and give me a assignment so when I watch this i understand n complete my assignment 🙏🏿💔🙏🏿
You are a miracle worker💯
You're the hero we need
Thank you really helpful, my professor forgot to upload the lecture video for the hw due in a few hours
My favorite channel,therefore every video that I watched makes sure subscribe and give thumbs up to appreciate him..top
Long life for this channel
So basically the variance formula is same as the STD without the square root. thanks a lot buddy.
I see that you've understood everything without a problem, would you mind to give me some extra easy examples? You dont have to explain it in word, just example of set of numbers and the actual computation? Please i beg of you 😢
@@asdfghjkl-vq2qz
I can help you
I needed this when I took statistics
Thank you so much for your help! It’s easier when you teach it.
Thanks for the video, I literally thought regular standard deviation was the same with Population and sample deviation
Thanks! I got a quiz on this tomorrow!
Wonderful video thanks for such a helpful video. And thanks to a teacher who helps their students in.
Quick question, why is the standard deviation calculation you made for 3,5,7 not over n-1? I thought that 3,5,7 was a sample of the population 3,4,5,6,7. Just asking for clarification. I appreciate your channel it really helps me learn. Especially when I don't understand my professor, so thank you for your work.

I also thought this, is this a mistake?
he just did the population standard deviation and not the sample.
The sample formula is with n-1
Dude honestly thank you it took me 6 mins to learn it and perfect it rather then 45 mins 😂
Thanx for the demonstration message be blessed
I love how I watched this video back in Yr10-12, thinking that I won't ever need it again, while laughing at ppl in comments that are using this video as a guide in collage and uni
Now in second yr of uni, im back to here again cuz I forgot every shit I learnt from my past, and i finally understood why there r so many ppl in here. my professor sucked at explaining the concepts
He just knows what we need😭
