Calculating Sample Size (n) to Estimate Population Mean

[@haweyorashid9419]

Everything is straightforward. Thanks, man, you have helped a lot

[@joshemman]

My pleasure, Haweyo. Thanks!

[@afghankodak7468]

I WATCHED 3 OF YOUR VIDEOS. GREAT EXPLAINATION! EASY WAY

Thank you very much sir. I'm now enlightened

[@adamjuckniewitz727]

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

[@joshemman]

Thanks fot subbing, Adam. I really wish I could help, but I don't have/use the TI84.

[@gebrugebremeskel373]

sorry, would you tell me how i can calculate sample size for survival data ? for the population 2128

[@Eddie-e2q]

Wow this really understandable

[@joshemman]

🙏

[@lukaskinezi430]

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?

How does the result show that we need more than 109 please?

[@cristobalvalladares973]

That was great. Thank you!

U are amazing!

[@fintancolaco7398]

Beautiful voice

[@mercymwariri338]

Can u please explain why you picked 110 instead of 109? where does the result show this detail??

[@joshemman]

You always round up to the next integer. Whether it is 109.8 or 109.1, you round up to 110. It means a sample of size 109 is not enough to achieve that error limit; you need an additional unit.

Cool. Does anyone have the bibliographic reference to cite these formulas?

[@joshemman]

You can derive it yourself: online.stat.psu.edu/stat415/book/export/html/800 or see Wikipedia
