Had summer class because of this. Was still confused in summer class. This helped. Then 2 weeks after summer class, I’m back in school. Which is bullshit.
I have enrolled in Sophomore level (University) statistics, just to drop it, like 4 times, because I knew, before the midterm, that I was not going to be able to pass it. I finally did, with a C. Not my best work. I am an A/B student. Years later, I am back in school for a second degree, and I am having to re-take statistics because the statistics I have credit for is "statistics/business majors" and now I am a pre-nursing student, so they are making me take regular statistics (not for business majors), which I think is ridiculous, considering its the same material, same book, same chapters are covered, but I digress. I had a melt down when I found out I would have to take this class again, especially as it is the last class I have to take to enter nursing school. If I had access to these videos way back when, I could have passed statistics the first time, with an A. I have a A in my class now, and am breezing through, with EASE. This class used to keep me up at night, stressed beyond belief. I am actually enjoying it now. It amazes me, the difference it makes, when you have a GOOD teacher. I cannot thank you enough for your time and effort put into this channel. You have saved me from a guaranteed ulcer.
Taking college stats & your teaching is sooo helpful & I can actually understand the material. You are very passionate about statistics & it shows! Thanks:)
When you wished that this guy could have been my math teacher when I was in school. Thanks for explaining everything so clearly. Getting ready to take my Math 4-8 certification exam -- I finally get it! Thank you!
thank you so much for this video, I had missed this class and didn't know how to do it. with your explanation and visuals I learned it so fast as was able to finish my work all today. you are a god send
Maraming salamat po! ❤️ Today is our exam and it was so difficult for me because I'm not really into Math 😭 then finally i understand this way of solving than the examples in textbook. THANKYOU Prof!❤️
I know this video is old but it just saved me I am horrible at math never really understood much in it but the way you did this step by step is easy terms was so helpful and helped me understand what I was actually doing and had to do so thank you!
I got confused about the square root of 8.69=9.32, I thought my answer is wrong, thanks to the guy who noticed the answer. Anyways thank you, Mr. Brian, your videos are a big help to me.
Wow, thank you so much for clarification of variances for me. I am currently finishing my masters degree and haven't take a statistics class. So this does explain the concept well. Thanks again!
YOU are amazing!!! Do you have more videos?? You just taught me in 8 minutes what Ive been struggling to understand in one whole week.. Stats is my very last class standing between me and my BA and Ive been putting it off for a whole year bc every time I sit to do my homework, I cry.
I think the teacher uses n instead of -n as the divisor because the problem is for a population, not a sample of a population. That important point should be included in the lesson. The concept is difficult enough without explaining this crucial point.
Hi Brian. Just tried this method solving variance for nos: 8,8,9,12 ...and I got 2.68 for variance. Did I got the correct answer? Just checking if I did the right solution 😊😊😊
I paused ur video and getting root wrong.. then i started ur video i got the same answer in the laste bcz u took wrong root by mistake.... Sir vry nice teaching method....👍👍👍
He is right because he is dealing with total population which is n=10 and we use n-1 where we are drawing sample from the population. For more brief lets take as example If we want to measure height of one class of 15 students and we are taking all the students so it means we are taking whole population (Class of 15 students). Here we use 'n' not 'n-1'. If we want to measure height of one all students in a university which are 1500 students and we are taking only 15 students so it means we are taking sample from whole population. Here we use 'n-1' not 'n'. Hope explanation will assist you.
I was about to go back at the previous minutes of the video, but decided to just finish the whole lesson. Thank goodness it was corrected just a few seconds later.
IM SUBSCRIBING NOW lol you are awsome, taking online statistics in college and its almost entirely self taught and the presentation videos are all from like the 80s wanting to use the TI 89 calculator ? or whatever its called lol didn't show me jack on how to do this and the text book barely explains it.. I swear they keep adding in new technology so the teachers have to do as little work as possible.. i actually hate talking face to face but the longer I do online schooling the more I just wanna call up my teacher lol... anyways love the video thanks a bunch
When you realize you can learn and learn a whole semester semester of math in a day of watching UA-cam.
i learn more here than the 30 minutes in class
true. i understand lessons here than my own math teacher discussing idk words in front of the class.
You are absolutely right.
Had summer class because of this. Was still confused in summer class. This helped. Then 2 weeks after summer class, I’m back in school. Which is bullshit.
Try an hour before an exam
Thanks to you I'm passing my online college statistics class!! The chart is a great idea !!!! Thank you!
As always great. He actually explains the problem that's why he's a good professor!
truth bro!
When he explained it better than my math teacher
Richard getting called out like that smh
ohh Richard
I learned all of this in just 8 minutes after it took me days to try to understand my statistics text book. Great videos !👏🏼👍🏼
Same here!!

Thanks:)
Do you have a playlist for statistics? I will like to watch all your statistics videos please. Your teaching style is amazing. Thanks in advance
Thank you
Yes!!
Man, I was so excited when I clicked on this video and saw you! I used your videos in high school and now I'm using them in college
love you sir, I am from india.
your teaching style is so nice
you are the best teachers on UA-cam that I have ever came across who solves problems step ny step
When you wished that this guy could have been my math teacher when I was in school. Thanks for explaining everything so clearly. Getting ready to take my Math 4-8 certification exam -- I finally get it! Thank you!
Thank you so much. You are an excellent teacher and glad this video is still around. I hope you have a whole lesson(s) on stats.
Just wanted to say THANK YOU. You are a good teacher,
now that you said it i got confused
I am so happy that John Fetterman teaches math :) Couldn't make it through school without you,
thank you so much for this video, I had missed this class and didn't know how to do it. with your explanation and visuals I learned it so fast as was able to finish my work all today. you are a god send
this guy just gives off the perfect math teacher vibes, I can't explain it. thank you so much!! videos are always so helpful
Some teachers have skill issues
I couldn’t remember how to find the variance so I had to watch a video to refresh my memory. This video was very concise. Thank you.
When I spent my day reading books but learned nothing so I swallowed my pride and watched youtube
Why would you need to swallow your pride lmfao
@@randomguy8228 because I thought i don't need help. Simple as that LOL
Maraming salamat po! ❤️ Today is our exam and it was so difficult for me because I'm not really into Math 😭 then finally i understand this way of solving than the examples in textbook. THANKYOU Prof!❤️
Omg, thank you soooooooooo much, you explain it very well!!!!
happy to be able to help!
well this is the second time this channel has helped me with my college math work.
Thank you so much for this valuable help. This video saved me in my master's program.
Thank you so much for this video! If it wasn't for this video I would have struggled hard with my statistics test.
Thanks you are very good at explaining your steps and using new methods! Your awesome!
you are very welcome! happy to be able to help
I am confused I thought it was n-1 at bottom instead just 'n" for the variance. Like devide by n-1
For the variance, isn't the summation of (xi-xbar) squared divided by n-1 rather than n?
yes, that is why i am a bit confused.. i calculated it and devided 86.9 / 9 = 9.65 the variance, for standard deviation it is = 3.10
Maybe he got confused but it is supposed to be n-1
@@gabebarbieri194 You're right
He may have forgotten to add -1
I know this video is old but it just saved me I am horrible at math never really understood much in it but the way you did this step by step is easy terms was so helpful and helped me understand what I was actually doing and had to do so thank you!
You are so brilliant! I have learned more from your videos than my actual classes and text books. Thank you so much!
Good teacher👏🏽

Thank youu! i finally undestand how to get the variance have a good day!
U'r the best it's simple, understandable and helpful .🙏
love u bro i believe that with the power of Mr bryan mclogan I can pass my statistics quiz today Amen thank you bro
i second that! we love you 🧔♀- ap stats eia
Wow, thank you so much for clarification of variances for me. I am currently finishing my masters degree and haven't take a statistics class. So this does explain the concept well. Thanks again!
Thank you, I am in an online practical math class and this video is helping me!!
Been a fan of your channel for a long time now and you have helped me once again, thank you so much.
Very thorough! Wished you were my previous stats prof. Explained well.
YOU are amazing!!! Do you have more videos?? You just taught me in 8 minutes what Ive been struggling to understand in one whole week.. Stats is my very last class standing between me and my BA and Ive been putting it off for a whole year bc every time I sit to do my homework, I cry.
I have over 12,000
Thanks for sharing..it really helps..now that I am answering my assessment in statistics.
WE LOVE MR MCLOGAN💯💯💯

This is perfect! Just what I needed !! Thank you .
I became one of your fans man!
Thank you so much🎉❤ my math teacher is brilliant but I'm ADHD and sometimes I need things said a different way. I just aced my math question
I get it, so happy
To be here for you!!
thank you! taught me more than a powerpoint that my professor gave me!
very well explained thank you very much.
the way he wrote 66 was amazing 2:09
Richard gettin called out LOOL
Helpful 5 minutes before my algebra final.
Thank you..this helped alot!
2:07 nice
Nice
Nice
Nice
haha
You are better than my prof.
I was about to question why he got the incorrect SD, yet I was glad it was raised by the student lol
Thank you for making me understand gracious
This upload helped me a lot, thanks Brian!

thank you for teaching me
You got me through Algebra 2 and Stats
You'ee a savior ◉‿◉ I learned more in 8 mintues than 1 sem hahahahahahahahahah
This helped so much🙏🏾🙏🏾Thanks!
This guy is a legend!
Thank you, very helpful
Math is easier if it is taught by a good teacher
MR BRIAN I LIKE YOU FROM PAKISTAN, YOU ARE ALWAYS HELPFUL TO ME
It should divided by n-1
yeah youre right. I went to go put the answer in mhy Homework and it told me n-1 and also 8.69 divided by 10 is 0.869
@@stephaniesepko6843 it's 86.9/10, not 8.69. 8.69 is the variance.
Yh u are correct
That’s only for a sample variance, he’s doing a population variance, he’s very correct
He is right because he is dealing with total population which is n=10 and we use n-1 where we are drawing sample from the population. For more brief lets take as example
If we want to measure height of one class of 15 students and we are taking all the students so it means we are taking whole population (Class of 15 students). Here we use 'n' not 'n-1'.

Hope explanation will assist you.
i’m so bad at math that i cry over it and i’m going to have to use this whole table method to actually be able to do this thanks for making it easier
You have made my life easy, thank you
I know I'm very late to the party just reviewing standard deviation what exactly did you do at 6:46 I didnt quite catch that
Yeah me too
Thank You!
awwsome teaching method.....thankuuu sir
THANKYOU Sir 🙌
omgg i was so confused at the end and kept going back just to find out 30 min later it was wrong😭
Litterally 🤣 i was sitting there like.... 🤨 wayment
Hahahha ify
IKRRRRRRRRRRRRR

Thanks you so much
thank you.. very descriprive
You are very welcome!
When do you use n-1 for variance to divide? Bc I divided by n for my work, but my teacher told me dividing by n-1 is the correct way to solve
This is what I am confused about now did you ever figure out the proper way
For sample values you use n-1 and n for population values
w reply@@sellahyekha4349
How am I supposed to know if it's a population or sample?
good example. thanks
Thank you sir
Super helpful, thanks!
thank you!
Thank you so much for this!
Can't believe an hour and a half of STATS class and I was still so loss, just for an 8 minute video to make me understand lmao.
freaking Nathan man, guy cracks me up
thank you so much for the help!
This was useful but the for the standard deviations it n-1 and not just n
Thats for sample variation s²
Can you explain why the MEAN is 66.1 and not 66? Where did the .1 come from? Thank you
I'm sure you know now as this is 3 years old but the mean is average and I'm pretty sure you were thinking of median
Wow ❤️ amazing sir
Thanks you I have exam tomorrow ❤
Thank you so much for the wonderful content!
