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.
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
@@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 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
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!
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 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
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)
Good question! If they never mention the word sample or population in the question, always assume it is a population either way the answer will be the same for both at the end!
In the clinical laboratory we use sample deviation, not population. 20+ years ago I was only taught sample deviation. The population deviation will be slightly lower than the sample deviation. In most cases it would not matter which one you used, however, there may be some cases where it does change how you would round the standard deviation.
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
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.
Thank you. You made this operation worked out by using simple definitions for each term ,which by the way, I have not seen that happening in the guide books. So, thanks.
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! ua-cam.com/video/ANsVodOu1Tg/v-deo.html

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

hi
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)

You saved a life
Long life for this channel!
Whenever I get homework, this is channel is my first stop. This guy makes maths fun and easy to learn.
Thank you for the most understandable explaination. I understand literally NOTHING of what my prof said in the class. YOU ARE MY LIFE SAVER.
I know there's someone here looking for better teacher than in our online class teacher this pandemic. 😁
I’ve had the flu and missed classes this week thank you sir for helping me catch up.
Thank you, you’re actually better than a university lecturer. Crazy!
Your voice is so tranquil and your breakdown is so easy to understand
thank you so much you help to students who are preparing 24 hours before the exam, keep it up
Definitely me right now
prepping 12 hours before... yikes
Moderate voice, standard explanations...everything perfect
Yeah this guy is fantastic
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
Your videos help me, you are much clearer explaining these problems than my professor and textbook
Really love your voice and your explanations are always on point! Good job! Happy that I found your channel.
You explained this ten times better than my teacher did.
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

I am your fan!!!!!!! You are amazing at explaining!!!! And your tone calms me down, which helps me to understand!!!!!!
I'm about to take an exam and bro you are a lifesaver definitely got that follow.
Thank you for detailed explanation , your video is always the best. Your are the reason I understand and pass my math classes.
Thanks!
You are a genius and the reason why my understanding keeps improving, thank you for the content!!!
ha ha i understand more from you than from my teachers explaining in my native language. thanks, man! you re awsome!
you teach better than my prof .
God bless this guy
He's teaching skills are so special 👌
the comments on math videos are always positive. and like: this video taught me in minutes what teacher couldn't in weeks😁😁
May Allah bless you thanks 🥺🤝🏼👏🏻👏🏻👏🏻👏🏻👏🏻👏🏻i pray to Allah to bless and guide you to the right way of beautiful life here and hereafter
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)
I always find his videos helpful. Thank you so much
How I would know if it sample deviation or population deviation if it doesn't mention that in the question
Good question!
If they never mention the word sample or population in the question, always assume it is a population either way the answer will be the same for both at the end!
@PRINCESS NAA OFEIBEA QUARCOO Are you sure
The video is cutting off, I can not hear well, it cuts off.
In the clinical laboratory we use sample deviation, not population. 20+ years ago I was only taught sample deviation. The population deviation will be slightly lower than the sample deviation. In most cases it would not matter which one you used, however, there may be some cases where it does change how you would round the standard deviation.
@@vanessajohnson3952 thanks ^^
Thank you bro, missed 2 weeks of class and this is saving me.
This helped me several years ago and now I’m workong and using this in analysis. thank you
seriously thank you so much, all my professor did was the way to find standard deviation is just do this equation here .
You just saved my life thank you so much!!!! I have a midterm, and without this video I would of failed lmfao.
A big thanks to you, this really really helps alot, i understand this lecture alot more than my Math teacher...
I've been revising for JEE & other exams from your videos! Thanks a lot!!!
yo how did your jee go
This guy helped in Differential calc, then integral calc, then stats, now in GIS courses 🤝
the way u said sigma, made my day🥰🥰🥰
i have exams this upcoming week, and you teach me better than my lect
This Guy is the Hope of mine in whatever mathematics challenge i face,A big Shout out to you Sir
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
thank you very much you have no idea how much you are helping me
i finally know how to do math, im so grateful for your account TT
First of all, I love his voice but he helps me understand.
You are a hero for all people with math help!
Thank you professor, currently busy witha an assignment.
dude this account legit saved my life
thanks for your explanations! you've made online statistics so much easier to learn!
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 🙏🏿💔🙏🏿
God bless the organic tutor he's such a life saver
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
You're so Generalist to explain about all science disciplines briefly
My favorite math youtuber
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.
this guy deserves everything
You have a good method of delivering lectures
My favorite channel,therefore every video that I watched makes sure subscribe and give thumbs up to appreciate him..top
Thanks a lot, super concise and clear, you're a blessing man.
this guy made standard deviation so simple but my teacher in school gave me a long winded complex explanation I did not understand
Thank you so much❤ this literally saved me from my exam this week
Thank you. You helped me get more statistics homework in on time.
Quick question, you mentioned that with sample standard deviation you do N - 1 which you didn't end up doing in the end of video. (8:30)
because it is the same process except you do n-1 instead of only dividing sum to n
You are way better than my ap stats teacher 😢😢
OMG...this video was so helpful...the stress all long gone...thankyou very much..
you explained this wayyyy better than my teacher. im finally gonna do good on my retest. thank you so much sir
Thank you really helpful, my professor forgot to upload the lecture video for the hw due in a few hours
Just wow dude! great job!. simple to understand. thank you very much
How does population SD work if you have a data set of 50 values? You have to do each one individually? value-mu?
He is way more better than my professor .
Dude honestly thank you it took me 6 mins to learn it and perfect it rather then 45 mins 😂
Thank you soo much for breaking it down for me. My book, nor my professor provided this specific information.
Your voice is so calming I love it I wonder what you look like in life)
Well and simply explain, My best online tutor.
Thank you. You made this operation worked out by using simple definitions for each term ,which by the way, I have not seen that happening in the guide books. So, thanks.
Thanks for the video, I literally thought regular standard deviation was the same with Population and sample deviation
I love this man, but the ads come right when I’m making a break through and then I lose focus
Man! you are G.O.A.T👏
Thank you so much for your help! It’s easier when you teach it.
Wonderful video thanks for such a helpful video. And thanks to a teacher who helps their students in.
I like the way you simplify it. Thank you.
Thanx for the demonstration message be blessed
You are a miracle worker💯
You have save me so many times!!! Thank you!

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
this is very helpful, everything is explained very simply. subbed
