WebDesign Weights Design weights are used to compensate for non-proportional stratification. For example, in a population containing 100,000,000 men and 100,000,000 women, if you used quotas or stratification to achieve a sample of 80 men and 20 women, then a design weight is created to take this non-proportional stratification into account. WebDesign weights are constructed in order to mutually adjust individual units’ probabilities of being sampled, which are normally not equal when complex sampling procedures combining multiple methods (stratification, group …
