Sample size determination

Sample size determination refers to the process of determining the appropriate number of participants or observations needed for a study to have sufficient statistical power to detect meaningful effects. It is a critical step in research design and is a major component of experimental design. The goal of sample size determination is to ensure that the study has enough statistical power to detect significant differences or relationships between variables.From: Bayesian Ideas and Data Analysis [2019], A human factor approach to distribution network design for e-commerce in supply chain system: a case study [2023]

Some sampling methods are mentioned here: Sampling methods (there are several choices. Depending on the situation any one of these is acceptable: simple random sampling; systematic sampling; stratified sampling; probability-proportional-to-size sampling; cluster sampling; quota sampling; minimax sampling; accidental sampling; voluntary sampling; line-intercept sampling; panel sampling; snowball sampling; theoretical sampling.)Replacement of selected unitsSample size determination (steps for using sample size tables)Sampling and data collectionApplications of samplingErrors in sample surveys (sampling errors and biases; non-sampling error)

Sample size determination is a critical step in research design as it helps to ensure that the study has enough statistical power to detect meaningful effects. The determination of sample size involves several factors, such as the desired level of statistical power, the level of significance, the expected effect size, and the variability of the data.
