From samples to populations: estimation and hypothesis testing.

چکیده
We previously described how data from family planning research can be presented and summarised.1 In this paper we will describe how to use data obtained from a sample to answer questions about the population. For example, we might use data from a survey to estimate how many women purchase hormonal emergency contraception over-thecounter from pharmacies. Or we might seek to answer the question, does taking the oral contraceptive pill (OCP) increase the risk of cervical cancer?
