Critical value (z*) for a given confidence level | AP Statistics | Khan Academy

[@intrepidh3084]

I learned more about finding the z value in this 6 min video than I did with my very expensive stats college course. I would have had no hope were it not for Khan, thank you so much!

I don't care what people say, Sal is the Macdaddy of online tutorials. No one can make it make sense like Khan Academy. Just shup up. You know it's true. Thank you Khan Academy for this god-given tutorial on anything math.

You say “we’ve done this in other videos” but don’t leave a link

5:00 is what I was having so much error while reading the z score table and taking the wrong number ....now I get... really thanks

[@zainebsiddiqui9392]

you saved me Sal. God bless you!

Nice explanation

[@We_Need_To_Talk_About_Dougie]

1.88 is 0.96995 and 1.89 is 0.97062 on my Z table. Say I wanted the Z* critical value to be more exact, and be rounded to 4 decimal places, rather than just two (like 1.88). How do I do this? I’m sure there’s a simple formula for figuring this out

[@farid6072]

I finally managed to find the answer myself thanks to other videos on KZbin. I appreciate what you have done but I cannot say your explanation was simple or learner-friendly.

[@cafehaven2]

with respect, you keep saying unrelated things, like you hide something in your words , poor teaching unfortunately or maybe just marketing either way still poor teaching thou

The videos are taken directly from their website, and you're meant to watch the videos throughout the unit in order. Consequently, he might do some review at the beginning of a video or introduce something at the beginning (just like how a real teacher might) despite whether or not it's related to the current video or is related to something else

You are a stupid idiot that should stay far away as possible from meaningful careers like actuaries or engineering. The fact that you can't understand the best online tutor to have ever existed says infinitely more about your stupid a$$ than khan academy. Please stick to plumbing or lawn care. You stupid idiot.

[@bladeiron]

This video is helpless in the upcoming exercise; you'll just end up looking up the hints and being confused as to why by Sal's logic used 94% while by the excercise's logic you use (100% - 94%) ÷ 2 instead.
