A comparison between convenience sampling versus systematic sampling in getting the true parameter in a population: Explore from a clinical database: The Audit Diabetes Control Management (ADCM) registry in 2009

摘要

Systematic sampling is an ideal sampling technique when sampling frame is not available. Dealing with patient's recruitment make convenience sampling is a choice for most of clinicians. We compare results derived from analysis of eight sub-samples with the true parameter from the population based on convenience sampling with first come and first serve basis and systematic sampling. This paper discussed at what extent convenience sampling with first come and first serve basis can be a valid sampling technique in comparison with conventional systematic sampling.
