Sampling weights are recommended to be incorporated in surveys to compensate for the disproportionality of the sample with respect to the target population of interest . This report presents how to develop sampling weights for a population -based study where a sample was randomly selected and demonstrates the process of developing such sampling weights . We exemplify the development of sampling weights with a real research project entitled School Physical Activity and Nutrition (SPAN ) project . In this report , we first introduce the probability -based survey and related key concepts , such as sampling design , sampling frame and sampling weights . Then we discuss the sampling design and the construction of the sampling frame for the SPAN project . We next demonstrate the method and the process of developing the sampling weights for the SPAN project . Lastly , we present the results with an example . |
