Webb2. Less time consuming in sampling. Use of sampling takes less time also. It consumes less time than census technique. Tabulation, analysis etc., take much less time in the case of a sample than in the case of a population. 3. Scope of sampling is high. The investigator is concerned with the generalization of data. Webb21 juni 2024 · A simple random sample is a smaller segment of a population in which each element of the population is just as likely to be picked as any other. It’s a basic tool in an analyst’s toolkit designed to obtain an unbiased sample by selecting items entirely at random from the larger population.
