This problem is similar to certain sampling issues in population genetics [ 33].
It can be estimated if two sample populations are distinct from each other, to a certain level of statistical confidence, using the T test knowing the sample mean and variance of our test samples, for a specific number of samples.
Although, unlike quantitative studies, qualitative studies are not required to achieve a certain sample size per se, the limited numbers require caution when generalizing to the wider population.
If there are differential response rates from certain groups in the sample population, then generalisability of results to the target population is questionable.
In our analysis, we retrospectively observed the usage of certain drugs preventing CV events in our sample population.
The value of work in population genetics increases with the number of analysed genes from a certain population sample.
Even though the sample is representative for a certain time frame within a local region of Switzerland, the sample population of female offenders remains quite small.
SUDAAN calculates variance estimates after incorporating the nonrandom sampling design and the sample population weights, which account for oversampling of certain subgroups.
This is probably due to our sample population was ascertained through two institutions from certain geographical areas of the country (Bangkok).
