How to calculate sample size in descriptive cross sectional studies (Prevalence studies) 

Very informative! Thank you

Thank you sir for the explanation. I want to calculate the sample size for a cross-sectional survey of unknown prevalence. Can I take p=50% as you suggested? I don't have the prevalence data for the consumption of processed packaged food in the city I am surveying. Or can I take the prevalence data of the country if it is available? please help.

Thank you sir, in this cross sectional study, the formula for descriptive and analytic studies uses the same formula?

So helpful for my research study.

whyyyy there's no comments! This video's really helpful especially for novice like me

I think this will help me in my research study, thank you.

Can we use prevalence of systematic reviewa and meta analysis ? If recent prevalence is not found

Thank you so much! I never thought statistics will make since to me.
