This guy helped me so much with my Chemistry and now Statistics. How can one person help someone so much and not meet them. I thank you Sir!

I have gotten an A in all of those classes in large part because of your videos. I have no doubt you’ll help me breeze through Statistics as well. Thank you.

THANK YOU!! After just 2 mins of watching this I have understood more than I have my entire year of stats class

You know what? I’m in mathematical statistics 2 right now and both of my math stats professors brushed over variance, but I wonder why they never went over this particular fundamental! I thank this guy so much, because now I have a better understanding.

When I get rich Amma always remember this man😂❤️

I like how you went further beyond the initial calculations to simplifying it. most videos are not able to do that. Keep on doing it like that for those of us who don't have strong basics in the subject, statistics and those who need to refresh on what they learnt long time age. You are the man!!!

Like S Sims- you have helped me through Chem, O Chem, all of my math classes, and now Stat’s ! You are brilliant, and I appreciate your videos, your teaching style, and love the fact that you do so many examples ! Thank you for sharing your knowledge with us, and for helping us all to get better grades in school ! You have helped me to get several A’s over the years, and I recommend you to other students looking for outside help from YouTube University!

Consider making a video on Mean Deviation for people that might need it

This man just rescued my Physics degree. I love you, good sir!

Great help! I use variance at work, but a simplified version of this statistical variance to deal with individual differences in semi trailer weights. Knowing this made understanding the official business stat variances easy, however, jumping into business stat from only knowing a single application of workplace variance was a bit daunting. This video made it easy to understand the calculations and the wild equations!

[yeabsraamare]

ur perhaps the best teacher anyone could ever ask, live long and huge fan of urs

[Shuri_edits]

rn am in my second year in university and i really needed this!! 😊
Statistics brace yourself, I am coming for you!!

[sweetoneloves]

Good looking out Organic Chemistry Tutor. Wow ! why is it that we don't have a Professor like you in class. YOUTUBE always has the best Instructors.

When I get rich Amma always remember this man😂😂

[charlesbesmos]

Will remember this video when I graduate in 2022...God bless

[mercybanda]

Thank you for making my understanding easier... So clear and straight forward.

[leonne_]

Eventhough I got 3.0 grade on my chemistry I will still thank Mr. Organic Chemistry for teaching me in a little time.

[codmplays]

Everything I know about high school math right now, I owe it to this guy, thank you!

[lauris]

This channel is like a gold mine. Why would you need a school...

[uriahlerner]

Any chance you could do a series over linear algebra? regardless, hundreds of people owe good test and homework grades to you. Not the hero we deserved, but the hero we needed.
