The Normal Distribution and the 68-95-99.7 Rule

[10BOOBTUBE]

Very good. Helped me understand much better! Thank you!

[pjtechy]

can u gv me ur brain for 3 hours ?

[3loveme1]

thank you!!!

this helped tremendously.

[TryLovee]

Oh my gosh you are amazing! I pay my professor in college hundreds of dollars for him to teach me this stuff and it makes no sense, I log and here and watch this and instantly understand in 8 minutes. Something is not right with this equation...thank you so much (:

[patrickJMT]

@TryLovee you should probably send your tuition to me : )

[alhayatjamilah]

whoooooo! thank you, totally saved by bum :)

[wazscience]

thank god for people like you on the internet

[aaroncelt]

absolutely fantastic. Im gonna pass my Quantitative Analysis exam thanks to you.

Your better than my lecturer. Cheers bud

[derek19062]

LOL! your example at 1:00 is the same one as my teacher has. Did he copy off from here? :D

[dfjndsk2008]

make more videos!! you are awesome!!

[patrickJMT]

@dfjndsk2008 thanks, i am going to make a bunch more after the new year : )

[albythebest87]

you're the man!!! thankssss

[catherinehavok]

and by standard deviation i meant normal distribution curves, haha. oh my brain.

[catherinehavok]

ohhh thank you for this video, it explained standard deviation better in eight minutes than the four months of my stats course has thus far, haha.

[nanananatasha]

my prayers are answered, someone who can make sense of stats!

[icha219]

is this t distribution teacher?

[TheRealOsanji]

Wish I could push "like" more than once. Thank you!!

[Chaminade14]

2 people were high when they were watching this video

[patrickJMT]

@Chaminade14 that's ok too

[matthewjfontenot]

@Chaminade14 A lot more than 2 for sure ;)

[alrasw]

Patrick where do you fall in that normal distribution curve? in terms of IQ? I'm pretty sure we all know where...love u! your biggest fan Alana!

[Anabea]

Very helpful, thank you!

[bakopala]

Thanks man.You rock

[patrickJMT]

@bakopala happy to help : )

[camissecret1120]

[ASLstudentUSM]

Thanks a lot!!

[LeKden8]

Thank you so much!!!!!!!

[LeKden8]

Ad's in school lol

[revdj]

I assign videos for an online course. They have online homework discussion groups, where they talk about homework and stuff. This week, most of the postings were not about homework, but about how helpful this video was. I thought you should know.

DJS

[patrickJMT]

@revdj wonderful! i am flattered : ) tell everyone thanks for mentioning me!

[fraolabdi]

I was struggling with empirical rule before this video. My professor did not explain that much. Thank you so much! You are terrific! Bless you!

[valcarni1]

gotta love maths how u can do it anyway around... i did 100- (50+34)

[GoodDeedsLeadTo]

Patrick, I have watched various lectures on probability, Calculus and statistics.

You are definitely the best teacher, without a doubt.

You speak with proper pauses, proper ups and downs, & patience, and explain difficult concepts with clarity. You are not hyper.

God has blessed you with a great mind.

And, you are serving humanity by making your lectures available on yts.

God bless you.

[GoodDeedsLeadTo]

What is better quality in your view? 3 standard deviation or 1 standard deviation?

You are accepting lower IQ's with 3 standards deviations than 1 standard deviation, but you are accepting a larger population with 3 standard deviation form the mean than one standard deviation.

[animelovergal2002]

I'm planning to take Statistics after College Algebra, watching all of this man's Statistics and other Math videos are surely helpful

[vibins360]

Awesome.

[xVarsityx]

I have a test tomorrow and was so stuck on this, and you explained so well. Thanks!

[freakiestboi1]

Thanks this helped me a lot...I have a test tomorrow and i just needed this problem to complete my studying. Thanks again!

[jesusalvarado2009]

Great video! Thank you for your help!

[GoodDeedsLeadTo]

Hi Patrick: Could you show standard Deviation (six sigma) application to quality management, where they use DMAIC methodology (Define, measure, Analyze, Improve, Control) to reduce variability or defects? How can they use the formula 1 sigma is abs (pessimistic- optimistic value) /6 for one standard deviation.

[MixTheMeister]

You're the greatest teacher here on Youtube!

[patrickJMT]

@MixTheMeister thanks! : )

[RickittLover]

Why can't my teacher have just put it like that -.-

Thanks, I might pass my exam tomorrow now :)

[lalaheadxx]

Ty!

[vplof]

Patrcik what should I do to obtain the area if the normal distribution has a mean of 0 and a desviation of 2 N(0,2) ????

[patrickJMT]

@vplof convert to standard normal and use tables at the end of your stats book

[Dortitosman]

@vplof buy a stats calculator, just type deviaiton/mean/bounds and answer pops out

[SabaskaTheNoob]

would they ever ask you to find a value that is not equal to a standard deviation(s) from the mean? e.g., find population with less than 90% (with the standard deviation being 15%).

[patrickJMT]

@SabaskaTheNoob yep

[karindaolivo]

thank you so much I could not understand it until I saw this video

[metallica929]

If only all it teachers made it nice and simple like you do...

Patrick for president!

[robbhabb1775]

Thank You so much you are a God send!

[Solarissis]

OMG THANK YOU SO MUCH!!! I understand it now :D

[hardtrancelover92]

Thank you so much for uploading this video! You make math easy to understand! :D

*faves*

[TheClburrows]

thank you so much. x

[powerlove7]

omg you are awesome!!!

i was so completely stumped about this..my professor kinda stinks and i couldn't make heads or tails our of the freakin book..

so basically thank youu:)))))))

[weine91]

Awesome video, 8 mins on YouTube teaches me more than 50 mins in class. Thanks!

[kgmahabir]

Thanks so much this is helping me with my gr.12 data management course

[ya0ish3lly]

you are doing the exact problem that was assign to me X-x

[NOS7854]

I can not tell you how much this video helped me. You made it very user friendly and logical. Thanks!

[xstncd]

LOL OMG, my luck! This is EXACTLY what I need help with and its the newest vid especially since I am stuck with this. ps. my teacher sucks >>". THANKS PAT!

[patrickJMT]

@xstncd no problem!

[MrViperman50]

@patrickJMT i was wondering if you can do one for me, i dont know how to do it, maybe you can help me, my question is, lets say, i have a even number, then the next is even again, then the next is a odd number, and lets say i got 30 numbers in a row, and i would like to know what is the probablility of the next number, i would like to know the formula for figuring that out..

[Titan13213]

thank you soooooo much i actually understand you unlike my indian math teacher ahha

[yyourfacee]

@ItaniumShock statistics, maybe some probability? for sure statistics though

[Kurtlane]

Thanks, Patrick. It's very clear.

One question, though. The standard deviation of 15 - is that "the rule," or just the data for this specific problem?

Another question. I am looking for proof of the normal distribution formula Phi(x) = 1/sqrt(2pi*sigma^2) * e^(-(x-mu)^2/2sigma^2)

Do you know where I can find it? Also, who figured out this is the standard distribution formula? Any book you can recommend.

Thanks

[peychinhwee]

your video help me to revise my math after 10 years from college, I use to score A for math, but long time never practice it, you lose it. Good video.

[rminb010204]

@ItaniumShock Statistics, probably.

[SouIControI]

this is awesome! i just started learning this topic and you uploaded this!

Thank you very much!

[zalida100]

Thanks patrick - nicely done.

[jabberwocky685]

what do you do withall that paper?

[patrickJMT]

@jabberwocky685 it is about a foot deep in my little office/room, all around me

[jabberwocky685]

@patrickJMT oic! have you decided on doing ACT math?
