  2. Sample size determination - Wikipedia

    en.wikipedia.org/wiki/Sample_size_determination

    Rather than relying on predetermined formulas or statistical calculations, it involves a subjective and iterative judgment throughout the research process. In qualitative studies, researchers often adopt a subjective stance, making determinations as the study unfolds. Sample size determination in qualitative studies takes a different approach.

  3. Wells effect - Wikipedia

    en.wikipedia.org/wiki/Wells_effect

    This behavioral effect was first established in a series of experiments by psychologist Gary L. Wells. [1] This study examined the difference between how mock jurors judged naked statistics (statistical evidence that is unrelated to the specific case) and other forms of evidence, and found that a simple probability-threshold model (i.e., that jurors decide guilt when the subjective probability ...

  4. Bayesian probability - Wikipedia

    en.wikipedia.org/wiki/Bayesian_probability

    Bayesian probability (/ ˈ b eɪ z i ə n / BAY-zee-ən or / ˈ b eɪ ʒ ən / BAY-zhən) [1] is an interpretation of the concept of probability, in which, instead of frequency or propensity of some phenomenon, probability is interpreted as reasonable expectation [2] representing a state of knowledge [3] or as quantification of a personal belief.

  5. Overconfidence effect - Wikipedia

    en.wikipedia.org/wiki/Overconfidence_effect

    The overconfidence effect is a well-established bias in which a person's subjective confidence in their judgments is reliably greater than the objective accuracy of those judgments, especially when confidence is relatively high. [1] [2] Overconfidence is one example of a miscalibration of subjective probabilities.

  6. Forecasting - Wikipedia

    en.wikipedia.org/wiki/Forecasting

    Judgmental forecasting methods incorporate intuitive judgement, opinions and subjective probability estimates. Judgmental forecasting is used in cases where there is a lack of historical data or during completely new and unique market conditions. [24] Judgmental methods include: Composite forecasts [citation needed]

  7. Probability interpretations - Wikipedia

    en.wikipedia.org/wiki/Probability_interpretations

    Epistemic or subjective probability is sometimes called credence, as opposed to the term chance for a propensity probability. Some examples of epistemic probability are to assign a probability to the proposition that a proposed law of physics is true or to determine how probable it is that a suspect committed a crime, based on the evidence ...

  8. Risk perception - Wikipedia

    en.wikipedia.org/wiki/Risk_perception

    Factors of risk perceptions. Risk perception is the subjective judgement that people make about the characteristics and severity of a risk. [1] [2] [3] Risk perceptions often differ from statistical assessments of risk since they are affected by a wide range of affective (emotions, feelings, moods, etc.), cognitive (gravity of events, media coverage, risk-mitigating measures, etc.), contextual ...

  9. Bayesian inference in marketing - Wikipedia

    en.wikipedia.org/wiki/Bayesian_inference_in...

    Bayes' theorem is fundamental to Bayesian inference.It is a subset of statistics, providing a mathematical framework for forming inferences through the concept of probability, in which evidence about the true state of the world is expressed in terms of degrees of belief through subjectively assessed numerical probabilities.
