This video shows how to calculate the sample size n required to estimate the population mean µ. 00:00 Margin of Error 01:00 Sample size formula 01:12 Examples
So when population variability (sigma) is unknown use sample sigma instead denoted by (s) as n = (Z_sub{a/2} x SE)^2/E^2 where SEM stands for sample error of mean. Am I right?
Fantastic bro! subbing. Great format. Only thing could be to show it on the ti84 as well but I don't even know if that is something that can be done. Thanks
I WATCHED 3 OF YOUR VIDEOS. GREAT EXPLAINATION! EASY WAY
Thank you very much sir. I'm now enlightened
Everything is straightforward. Thanks, man, you have helped a lot

Thanks fot subbing, Adam. I really wish I could help, but I don't have/use the TI84.
Your video is so fantastic.
What software do you us for developing the videos?
Powerpoint & Camtasia Studio
Thank you
Thanks alot sir
sorry, would you tell me how i can calculate sample size for survival data ? for the population 2128
GREAT.
Thank you.❤
My pleasure, Nilanka.
Sir please add more video of pg level statitics
THANK YOU !!!!
Thank you 🙇♀️
You’re welcome 😊

how to get margin of error without N?
How to get 'a' by step by step solution?
Cool. Does anyone have the bibliographic reference to cite these formulas?
You can derive it yourself: online.stat.psu.edu/stat415/book/export/html/800
or see Wikipedia
BEST
how can i copy it to my document
What do you want to copy, and to what type of document?
Sample size of proportion
Where is this Vedio??
Sorry, no video for proportion yet.
thank u sir
