I am conducting a prevalence study for depression in adolescent girls (n=333 age= 15-19 years) in a peri-urban locality. This locality has 17 villages spread over an area of 11 sq meter, having a total of 8070 households and 2835 adolescent girls between ages of 15-19 years. I can easily get the list of houses and lanes in each village.
hello seema,
As you have mentioned that sampling framework is available, then i guess it would not be appropriate to predetermined the sample size (i.e., 333). In case of available list, systematic sampling is suitable and, in this case, the size of interval ll decide the sample size. However, if you want to apply multistage sampling, use any sample size determination formula at first. than allocate respondents proportionally to each village at second stage.
*for your guide, Cochran formula for sample size determination is best but to attain small sample size Tar Yamene technique is best fitted.
