[ 1 ] Incorporated in the design of a research study will depend on the standpoint of the researcher over their beliefs in the nature of knowledge (see epistemology ) and reality (see ontology ), often shaped ...
A person who possesses these forms of rationality to a sufficiently high degree may themselves be called rational. [1] In some cases, also non-mental results of rational processes may qualify as rational. For example, the arrangement of products in a supermarket can be rational if it is based on a rational plan.

Analytic study: A statistical study in which action will be taken on the process or cause-system that produced the frame being studied. The aim being to improve practice in the future. (In a statistical study, the frame is the set from which the sample is taken.)
Rational analysis is a theoretical framework, methodology, and research program in cognitive science that has been developed by John Anderson. [ 1 ] [ 2 ] The goal of rational analysis as a research program is to explain the function and purpose of cognitive processes and to discover the structure of the mind.
The sample size is an important feature of any empirical study in which the goal is to make inferences about a population from a sample. In practice, the sample size used in a study is usually determined based on the cost, time, or convenience of collecting the data, and the need for it to offer sufficient statistical power. In complex studies ...
