Factor analysis is used to identify "factors" that explain a variety of results on different tests. For example, intelligence research found that people who get a high score on a test of verbal ability are also good on other tests that require verbal abilities.
In multivariate statistics, exploratory factor analysis (EFA) is a statistical method used to uncover the underlying structure of a relatively large set of variables. EFA is a technique within factor analysis whose overarching goal is to identify the underlying relationships between measured variables. [1]
In science and engineering, root cause analysis (RCA) is a method of problem solving used for identifying the root causes of faults or problems. [1] It is widely used in IT operations, manufacturing, telecommunications, industrial process control, accident analysis (e.g., in aviation, [2] rail transport, or nuclear plants), medical diagnosis, the healthcare industry (e.g., for epidemiology ...
SWOT analysis evaluates the strategic position of organizations and is often used in the preliminary stages of decision-making processes [2] to identify internal and external factors that are favorable and unfavorable to achieving goals. Users of a SWOT analysis ask questions to generate answers for each category and identify competitive ...
PVA is also used to identify factors that drive population dynamics, compare proposed management options and assess existing recovery efforts. [2] PVA is frequently used in endangered species management to develop a plan of action, rank the pros and cons of different management scenarios, and assess the potential impacts of habitat loss.

Case–control studies are often used to identify factors that may contribute to a medical condition by comparing subjects who have the condition with patients who do not have the condition but are otherwise similar. [1] They require fewer resources but provide less evidence for causal inference than a randomized controlled trial.
Your paystubs should identify the amount that you pay in state income tax, or your employer’s finance department can give you this information. If you’re self-employed, your state’s tax ...
Factor analysis, the statistical method used to identify the dimensional structure of observed variables, lacks a universally recognized basis for choosing among solutions with different numbers of factors. [3] A five factor solution depends on some degree of interpretation by the analyst. A larger number of factors may underlie these five factors.
