analytical study

(redirected from explanatory study)

analytical study

A comparative study designed to reach causal inferences about hypothesised relationships between risk factors and outcome. Analytical studies identify and quantify associations, test hypotheses, identify causes and determine whether an association exists between variables, such as between an exposure and a disease. Statistical procedures are used to determine if a relationship is likely to have occurred by chance alone. Analytical studies usually compare two or more groups or sets of data.

Examples
Case-control study, cohort study, randomised-controlled clinical trial, lab study.

analytical study
one in which a phenomenon is described and an attempt made to analyze the effects of variables on the phenomenon.
descriptive study
one in which a phenomenon is described but no attempt is made to analyze the effects of variables on the phenomenon.
follow-up study
one carried out to find out whether there has been change in the situation since the initial study.
longitudinal study
one carried out over a period of time so that chronological time has an opportunity to exert an effect as a variable.
observational study
see descriptive study (above).
prospective study
one in which the data to be studied are yet to be generated, the events having not yet occurred.
retrospective study
one based on examination of existing data, on events that have already occurred.
simulation study
one in which the real circumstances are simulated, either in fact, or by means of a set of mathematical formulae each of which expresses the probability of each outcome in a series of consequential events that mirror the possible pathways in a real-life situation.
