Abstract
In this study, optimum allocation of n sized sample, which is selected from a population by Stratified Random Sampling under fixed budget, is examined. While doing this allocation, two different non-linear cost functions are used. Besides the situations, in which the variance of sample mean statistics is minimum under two different non-linear cost constraints are examined. The allocation of sample size into strata is harder and more time consuming when non-linear cost constraints rather than linear cost constraints are used. In this study, by taking into consideration of the situations in which neither objective function nor cost constraints are linear, the allocation of n sized sample that is selected from a population and its effect on the variance of sample mean statistics are examined by a simulation study.
