The article explores using two extra pieces of information to improve accuracy in estimating data in a two-step sampling process. New methods are suggested to estimate the average of a population at the current step. These methods are compared to traditional ways of estimating without matching data. The results show that the new methods can provide more precise estimates, leading to better decision-making.
