Answer: Sampling saves time by and large by lessening the volume of information. Tabulation, analysis etc., take much less time in the case of a sample than in the case of a population. The strength of pragmatic investigations are that they can: be easy to described and reported; be useful when unexpected results arise from a prior study; help to generalise data; be helpful in designing and validating an instrument; enable a researcher to develop a holistic analysis to fully incorporate numerous relevant factors into the study Compared to regular random sampling, stratified random sampling offers more accurate estimates since the variability within each and every stratum is reduced. Stratified sampling is a version of multistage sampling, in which a researcher selects specific demographic categories, or strata, that are important to represent within the final sample. There is simply more information from which to develop more hypotheses. Pragmatic controlled clinical trials in primary care: the struggle between external and internal validity.
