Sample size and design effect - alnap.org

WebThe design effect is a correction factor that is used to adjust required sample size for cluster sampling. The required sample size is estimated assuming a random sample, and then multiplied by the design effect. This accounts for the loss of information inherent in the clustered design. The design effect is a simple function of the average ... WebJul 6, 2024 · A ‘design effect’ is a useful and relatively compact term to indicate the influence of the sampling design on the uncertainty of each estimate. It was introduced by Kish (1994) and followed up on by other researchers (e.g., Gabler, Häder, & Lahiri, 1999; Shackman, 2001; and the ESS sampling team). bit o honey 5lbs
