  2. Water-level task - Wikipedia

    en.wikipedia.org/wiki/Water-level_task

    A 1995 experiment found that 50% of undergraduate males and 25% of females performed "very well" on the task and 20% of males and 35% of females performed "poorly". [1] Similar sex differences have been confirmed internationally. [8]

    en.wikipedia.org/wiki/Scientific_method

    The history of scientific method considers changes in the methodology of scientific inquiry, not the history of science itself. The development of rules for scientific reasoning has not been straightforward; scientific method has been the subject of intense and recurring debate throughout the history of science, and eminent natural philosophers and scientists have argued for the primacy of ...

    en.wikipedia.org/wiki/T-maze

    A study of alternation can be performed by repeating the experiment multiple times with no reward in either arm of the maze. Another experiment that can be performed is the alternation of rewards each time the experiment is performed, proving the rat will choose the arm that was not visited each time the experiment starts.

    en.wikipedia.org/wiki/Draw-a-Scientist_Test

    Chambers’ original 1983 DAST, based on surveys conducted between 1966 and 1977, [1] differs significantly, in both purpose and methodology, from the earlier Draw-A-Person and Draw-A-Man projective tests (such as Florence Goodenough in 1926; [2] Harris, 1963; [3] Goodenow, 1977 [4]), which have been used as a measure of intellectual maturation, to elicit personality type and unconscious ...

  6. Design of experiments - Wikipedia

    en.wikipedia.org/wiki/Design_of_experiments

    The question of design of experiments is: which experiment is better? The variance of the estimate X 1 of θ 1 is σ 2 if we use the first experiment. But if we use the second experiment, the variance of the estimate given above is σ 2 /8. Thus the second experiment gives us 8 times as much precision for the estimate of a single item, and ...

    en.wikipedia.org/wiki/Buffon's_needle_problem

    A Python 3 based simulation using Matplotlib to sketch Buffon's needle experiment with the parameters t = 5.0, l = 2.6. Observe the calculated value of π (y-axis) approaching 3.14 as the number of tosses (x-axis) approaches infinity. In the first, simpler case above, the formula obtained for the probability P can be rearranged to

  9. Event (probability theory) - Wikipedia

    en.wikipedia.org/wiki/Event_(probability_theory)

    In probability theory, an event is a set of outcomes of an experiment (a subset of the sample space) to which a probability is assigned. [1] A single outcome may be an element of many different events, [2] and different events in an experiment are usually not equally likely, since they may include very different groups of outcomes. [3]
