Is there any formula to know the sample size in descriptive cost analysis study

Hemant Deepak Shewade

Hello Dr Pankaja Raghav

Depends on what your outcome of interest is.

i) Prevalence of catastrophic costs or ii) median / mean costs.

If former, then may use the sample size for a descritpive study where the outcome variable will be summarized as a proporiton.

If the latter, then may use the sample size for a descritpive study where the outcome variable will be summarized as a mean.
