WebThis is a probability sample design, selected in two stages with probability at the first stage of 10/100 and at the second stage of 1/5. The overall probability of selecting a particular household for the survey is 1/50, that is, 10/100 multiplied by 1/5. 8. Though not particularly efficient, the sample design of the example nevertheless WebThe design effect is widely used in survey sampling for planning a sample design and to report the effect of the sample design in estimation and analysis. It is defined as the … Websame power as that of an SRS. For example, a sampling design with DE = 3 requires a sample three times as large as an SRS to achieve the same power [16]. Comparing sampling methods to SRS is mathematically convenient here because calculating power, and consequently estimat-ing sample size, is straightforward for SRS. Consequently, leachs shell mart
