Module 1 Lesson 1 Pdf Educational Assessment Sampling Statistics A sample survey is a method for collecting data from or about the members of a population so that inferences about the entire population can be obtained from a subset, or sample, of the population members. In survey sampling, survey weights can be applied to the data to adjust for the sample design. results from probability theory and statistical theory are employed to guide practice. Sampling theory provides the tools and techniques for data collection keeping in mind the objectives to be fulfilled and nature of population. sample surveys collect information on a fraction of total population whereas in census, the information is collected on the whole population. Techniques that allow us to make inferences about a population based on data that we gather from a sample. study results will vary from sample to sample strictly due to random chance (i.e., sampling error).
