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 WebGenerally, the homogeneity tends to increase the variance of a cluster sample for a given sample size when compared with a simple random sample. The effect of such increased variance is measured by a quantity design effect, or deff. The deff is the ratio of the actual variance estimate of a cluster sample to the variance estimated from a
