  2. Ishikawa diagram - Wikipedia

    en.wikipedia.org/wiki/Ishikawa_diagram

    Common uses of the Ishikawa diagram are product design and quality defect prevention to identify potential factors causing an overall effect. Each cause or reason for imperfection is a source of variation. Causes are usually grouped into major categories to identify and classify these sources of variation.

  3. Correlation does not imply causation - Wikipedia

    In these instances, it is the diseases that cause an increased risk of mortality, but the increased mortality is attributed to the beneficial effects that follow the diagnosis, making healthy changes look unhealthy. Example 3. In other cases it may simply be unclear which is the cause and which is the effect. For example:

  4. Risk factor - Wikipedia

    en.wikipedia.org/wiki/Risk_factor

    Specific to public health policy, a determinant is a health risk that is general, abstract, related to inequalities, and difficult for an individual to control. [2] [3] [4] For example, poverty is known to be a determinant of an individual's standard of health. Risk factors may be used to identify high-risk people.

  5. Bradford Hill criteria - Wikipedia

    en.wikipedia.org/wiki/Bradford_Hill_criteria

    Temporality: The effect has to occur after the cause (and if there is an expected delay between the cause and expected effect, then the effect must occur after that delay). Biological gradient (dose–response relationship): Greater exposure should generally lead to greater incidence of the effect. However, in some cases, the mere presence of ...

  6. Causal reasoning - Wikipedia

    en.wikipedia.org/wiki/Causal_reasoning

    In common-effect relationships, several causes converge in one effect: Example of multiple causes with a single effect An increase in government spending is an example of one effect with several causes (reduced unemployment, decreased currency value, and increased deficit). In causal chains one cause triggers an effect, which triggers another ...

  7. Causal inference - Wikipedia

    en.wikipedia.org/wiki/Causal_inference

    Causal inference is the process of determining the independent, actual effect of a particular phenomenon that is a component of a larger system. The main difference between causal inference and inference of association is that causal inference analyzes the response of an effect variable when a cause of the effect variable is changed.

  8. Proximate and ultimate causation - Wikipedia

    Causes and effects. Causes and effects from a common cause. One famous example of the importance of this is the Duhem–Quine thesis, which demonstrates that it is impossible to test a hypothesis in isolation, because an empirical test of the hypothesis requires one or more background assumptions. One way to solve this issue is to employ ...

  9. Root cause analysis - Wikipedia

    en.wikipedia.org/wiki/Root_cause_analysis

    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 ...
