Find Critical Value in Standard Normal Z Distribution

How to find a critical value z.05 in the Standard Normal N(0,1) Distribution, using either the Table or your TI-83/84 Graphing Calculator.

You're a life saver! No one decided to really explain that in my textbook. Thanks!

[@kristinemazziotti6455]

THANK YOU! I have a stats test tomorrow and this really helped me understand how to find a z-score when given alpha. You're a life saver!

[@mareyn2k]

Thank you! I never understood it until you showed that it was the opposite side of the shaded graph. Find the score for .95 NOT .05 (like I was doing). Thank you!

[@raddwest]

I just spent over an hour watching other long drawn out videos and you taught me what I needed to know in 3 minutes! Thank you!!!

[@sharettbrooks6676]

Thank you soo much!! You literally dont know how much of a lifesaver you are! My book didnt have the asterick to let me know how they got 1.645 so I was totally confused and the calculator trip totally worked and I can now use it in class! Thank you again!!

[@EmihleNgqisha-dd5yi]

Hii how dd u get 1.645

[@arcturion6995]

Thanks for this. Way better explanation than any resource I've tried to use thus far.

[@christinacadena508]

Thank you for explaining the calculator formula as well. Helped me so very much.

[@kylewarman897]

Thank you, still amazingly helpful 6 years later

[@lilyrojas4251]

Thank you! This is what I needed. My text book didn't explain this process :) Thank you so muchhh

[@iesparza2145]

This was so awesome. Short and sweet. Not only answered my question but helped me understand more of the concept. Thank you sooo much!

[@michellenator]

You explain so clearly and precisely, thank you so much!

[@phoebec.5212]

exactly what i was looking for and i finally know how it works, God bless you!

[@gizemylmazer7133]

Thank youuuuuuuuuuu you saved my life before the exam

[@blackwhite2361]

You still don't explain it well. How do I know to move to the second asterix. There is no asterix on a paper z score table

[@tokarefaat]

u r a lifesaver
thank u so much , u've no idea how much u helped me

[@nerdude2021]

i wish my stats teacher spoke English so i could understand this better like you just taught me.

[@SuperNatalie234]

Okay but what if the critical value is not there. How do you find it?

[@shubhamsingh1011]

this is what i was searching for. thanks fellas

[@demitri6605]

OMG What a champ. I was stuck with my stupid assignment and scrambling to fin Z, turns out out I was zzzzzzzzzzzzzzzzz *pun intended*

[@subjectlife82]

Good one

[@Staradams808]

This made all the sense in the world.

[@emilycontrino514]

Thank you very much for the clear and concise explanation!

[@jessicavandyke9693]

I do not understand! I am an online student and everytime I give an answer on this it's wrong

[@Shoobedooby]

Why doesn't my text book explain this? As if it wasn't overcomplicated enough... Thanks.

[@kamogelommankgeli3368]

O star,you are a star...danko

[@jengajune3886]

Thanks a lot, I was having a lot of trouble understanding what I am suppose to do though. Question though, what do you do if you don't have the middle point for the z scores, and your professor does not allow you to use to calculator to figure it out?

[@druceanrichmond535]

It was right on point. Thanks, I got it now.

[@fiona3555]

Thanks sooooooo much!!! Love your explanation!!!

[@immikeyy]

Thank you do much for helping me figure out how to do this on my calculator! :)

[@ariesfairies]

This is helpful for my statistics course, thank you! :)

[@vdimitris1]

I dont get how you take the last digit, the five on value 1.645. And what if it was 1.643?

[@xoppa09]

use the TI 84 invNorm function
z_.05 = invNorm(1-.05)
z_.05/2 = invNorm( 1-.05/2)

[@Unifrances]

Thank you so much. Your video helped me

[@kuldeeprajchaudhury1043]

Thank you very much

[@akidrosli7579]

How do I do this using this table but the test is two tailed? Because I am provided with this table(not the other z table)

[@nessieqey79]

Thank you so much. You help me for my task huhu 😭

[@heazzer012]

Sooooo very helpful!! Thanks!
