Thank you so much❤ my friends and I greatly appreciate this video. We have been struggling in stats class for some time now and your video is a life changer. Just know some seniors with senioritis love you.

Thank you very much for taking the time to put this together. I love the chart, this makes all the difference. There is no chart like this in my book. Thanks again.

Thank you so much. As a math teacher I checked it out before teaching my IB Classes. It is just GREAT.

I'm taking an online summer stats class and out of the dozen I've tried watching none have been as clear as this. Having the text on the screen and referencing as you go helps a ton for my learning style, thanks again!

I would not get through this Statistics class without your videos, my professor has a horrible accent and I was totally lost until I found u! Copied the chart the best way I could your a life saver

Thank you for the help. You break down the work to the bare minimum and don't miss any steps. I prefer your channel over all others on statistics.

Couldn't believe how easy you just made this concept. I'll be referencing back to this and the chart for sure. Thank you!

This video just saved me. Thank you so much! Taking online stats class is NOT easy

Suddenly got a wonderful insight into formulating a hypothesis properly - you are brilliant!!

Good tip at 6:20 ... saves you time counting and recounting to make sure you've written the number with the correct number of zeros after the decimal point.

Thank you for making this so easy to do on the calculator. I was lost trying to figure out how my teacher was coming up with these random p values.

I like your flow charts! Thank you, this video helped prepare me for my stat test.

[Hoeoclock]

you're the only reason I pass my ap stat test these days

[simonerochelle]

thank you for your clear and concise lessons. You truly saved my ass this semester :)

Hello! thank you so much for this by the way! You are sent from heaven !
Just one question though. Would this table work with t test or hypothesis prop testing? Sorry might be stupid question. I am just barely learning all of this.
thanks again!

[therealJohnLyon]

Can you add the flow chart to the video description?

[jameslamela]

Thanks a million! So much more understandable. Thanks again.

Can you please confirm? There's different answers/videos all over Youtube about when to use T-est and when to use Z-Test..The only time you can use a T-Test is when the Distro is normal (or approx) and "Population" Standard Deviation is UNknown? What happens if N<30? Do NOT use T test? According to your diagram theres only one time you can use the T test.

I love your charts. Really helpful. Thanks. I am having a problem understanding when to double the pvalue in a two tailed test. Can you explain?
