Sample Size Calculator Terms: Confidence Interval & Confidence Level. Sample is the part of the population that helps us to draw inferences about the population. × Close Log In. Research methods are the techniques and procedures used for conducting research. Statisticians attempt for the samples to represent the population in question. In statistics, quality assurance, and survey methodology, sampling is the selection of a subset (a statistical sample) of individuals from within a statistical population to estimate characteristics of the whole population. In multivariate research (including multiple regression analyses),the sample size should be several times (preferably 10 times or more) as large as the number of variables in the study. Sample size calculation is part of the early stages of conducting an epidemiological, clinical or lab study. 1 In some quantitative research, stricter confidence levels are used (e.g. Take the quiz to test your understanding of the key concepts covered in the chapter.
