  2. Range–frequency theory - Wikipedia

    en.wikipedia.org/wiki/Range–frequency_theory

    The range–frequency compromise in judgment is a theory in cognitive psychology developed by Allen Parducci in the mid-1960s. Range–frequency is descriptive of how judgments reflect a compromise between a range principle that assigns each category to an equal subrange of contextual stimuli and a frequency principle that assigns each of the categories to the same number of contextual stimuli.

  3. Collectively exhaustive events - Wikipedia

    en.wikipedia.org/wiki/Collectively_exhaustive_events

    When heads occurs, tails can't occur, or p (heads and tails) = 0, so the outcomes are also mutually exclusive. Another example of events being collectively exhaustive and mutually exclusive at same time are, event "even" (2,4 or 6) and event "odd" (1,3 or 5) in a random experiment of rolling a six-sided die. These both events are mutually ...

  4. Frequency (statistics) - Wikipedia

    en.wikipedia.org/wiki/Frequency_(statistics)

    A frequency distribution shows a summarized grouping of data divided into mutually exclusive classes and the number of occurrences in a class. It is a way of showing unorganized data notably to show results of an election, income of people for a certain region, sales of a product within a certain period, student loan amounts of graduates, etc.

  5. Percentile - Wikipedia

    en.wikipedia.org/wiki/Percentile

    In statistics, a k-th percentile, also known as percentile score or centile, is a score below which a given percentage k of scores in its frequency distribution falls ("exclusive" definition) or a score at or below which a given percentage falls ("inclusive" definition); i.e. a score in the k-th percentile would be above approximately k% of all scores in its set.

  6. List of probability distributions - Wikipedia

    Benford's law, which describes the frequency of the first digit of many naturally occurring data. The ideal and robust soliton distributions. Zipf's law or the Zipf distribution. A discrete power-law distribution, the most famous example of which is the description of the frequency of words in the English language.

  7. Mutual exclusivity - Wikipedia

    en.wikipedia.org/wiki/Mutual_exclusivity

    In this case a set of dummy variables is constructed, each dummy variable having two mutually exclusive and jointly exhaustive categories — in this example, one dummy variable (called D 1) would equal 1 if age is less than 18, and would equal 0 otherwise; a second dummy variable (called D 2) would equal 1 if age is in the range 18–64, and 0 ...

  8. Frequency illusion - Wikipedia

    en.wikipedia.org/wiki/Frequency_illusion

    More relevant to frequency estimations but still a possible cause of the frequency illusion, the split-category effect is the phenomenon in which, when events are split into smaller subcategories, this can increase the predicted frequency of occurrence. [10] An example of this is asking a person to predict the number of dogs in a country or ...

  9. Frequentist probability - Wikipedia

    en.wikipedia.org/wiki/Frequentist_probability

    John Venn, who provided a thorough exposition of frequentist probability in his book, The Logic of Chance [1]. Frequentist probability or frequentism is an interpretation of probability; it defines an event's probability as the limit of its relative frequency in infinitely many trials (the long-run probability).
