While there are many steps that can be taken to reduce this limitation, sometimes its effects (so-called sampling bias ) go beyond the control of the researcher. ![]() Instead, a randomized sample can be gathered, from which sample statistics can be obtained. These sample statistics serve as estimates of the corresponding population statistics and allow a researcher to make conclusions about a population of interest.Ī significant limitation exists in that these constructed samples must be representative of the larger population of interest. However, identifying this value would require having data for every single individual that falls into this category, which is impractical. For instance, in a study looking at obesity rates for patients on a certain medication, the population statistic could be the average obesity rate for all patients on the medication. Plainly, population statistics are the values of any measure within the population of interest, and estimating them is the goal of most studies . In order to entertain any discussion of statistical analysis, it is important to first understand the concept of population statistics.
