Yeah, I know, its pace is too slow for a lot of people. That's why I created a new updated one that is not only "more normally paced", but is more thorough in its explanations. I just put it up a couple weeks ago:

Hairy Larry Explains Confidence Intervals - Movie #1 of 5

I believe the standard error calculation is incorrect. 2.25 / 6 = .375 not .373.

[StatBrat]

Thanks for catching that! I have now "patched" the movie by pasting your correction over my wrong answer.

if we don;t knowwhat the population mean is then how would we know what the standard deviation is for population is..?

[StatBrat]

Here's the reason: It is easier for students to first learn Confidence Intervals this way (and there actually are a few real-life situations where the population standard deviation is known but the population mean is not). Then after you have learned the fundamentals of confidence intervals, then we teach about the t-distribution, which is what you use instead of the z-distribution when the population standard deviation is unknown (and so we use the sample standard deviation).

your voice.. just.. AGHHHHH. I'm not a child

[LadyDancer55]

This is good information you're talking as though we don't understand English.

[steeltalon2011]

The pace is just fine. It allows you to reflect on what you are saying.

This voice and choice of words makes me think about what kind of retard I must be to need an explanation video for a concept that SOUNDS like something 4 year olds learn.

[causa04]

thank you soooo much. you are really good... i understand now!!!

[Trackman2007]

Great explanation! Exactly what i needed to understand the subject to it's deepest levels.. & i really liked your voice and pace :D

[mehdigoudarzi]

judging fro your talking speed, i guess you haven't had anything to eat for the past 7 years. next time, try a RedBull before your Oscar Speech ;)

[TheCookieCrunch]

I must be the only one who loves your voice!

[Kateosaurus]

Oh my fock, no way is this to slow, it's perfect for me and you are saving my grade!!

[RockRocks98]

Honestly, if he talks too slow, go view a different stats video.

I for one am trying to learn this stuff for the first time, and its lot to take in, so I prefer the slower pace. Thank you for this video! Its a big help. I'm taking Stats online, which was a mistake. Therefore, youtube has become my Stats teacher.
