At the same time, the requirement that samples be representative of the population from which they are drawn has to be offset against time and other resource considerations. This being the case, choices have to be made between the mathematically superior probabilistic sampling methods and the more pragmatic non-probability sampling methods. Chapter Objectives. Questionnaire Design and Surveys Sampling. We must study the behavior of the mean of sample values from different specified populations.
Because a sample examines only part of a population, the sample mean will not exactly equal the corresponding mean of the population. Thus, an important consideration for those planning and interpreting sampling results, is the degree to which sample estimates, such as the sample mean, will agree with the corresponding population characteristic. In practice, only one sample is usually taken (in some cases such as "survey data analysis" a small "pilot sample" is used to test the data-gathering mechanisms and to get preliminary information for planning the main sampling scheme).
However, for purposes of understanding the degree to which sample means will agree with the corresponding population mean, it is useful to consider what would happen if 10, or 50, or 100 separate sampling studies, of the same type, were conducted. How consistent would the results be across these different studies? Is Var( Www.statpac.com/surveys/surveys.pdf. Www.zoomerang.com/resources/DS_SurveyDesign_Chklist.pdf.
