Question

Most researchers use the convenience sample because it is the easiest one to use. One of the biggest challenges of convenience sampling is that the results cannot be generalized. This means that studies that use convenience samples are often initial studies and then other studies have to be done to see if the results can be generalized or not.

Answer 1

Yes, convenience sampling is an initial strategy of designing the experiments with nonprobability sampling of the available different specimen sampling materials. It is a preliminary procedure but later probability sampling is desired if detailed analysis of the samples is required. This technique of convenient sampling is less costly, cheap and available at a number of centers in the country. It takes less time for the analysis of these samples in laboratories. This data lacks the generalization and the resolution power to analyze the target populations, groups and subgroups in a population of people living in low-socio-economic conditions. Homogeneous sampling, quota sampling and probability based population based sampling is used for analyzing the values of the demographic studies in various groups belonging to various communities and ethnic groups in various countries.
