  2. Naturalistic observation - Wikipedia

    en.wikipedia.org/wiki/Naturalistic_observation

    Naturalistic observation also allows for study of events that are deemed unethical to study experimentally, such as the impact of high school shootings on students attending the high school. [6] [5] However, because extraneous variables cannot be controlled as in a laboratory, it is difficult to replicate findings and demonstrate their ...

  3. Natural experiment - Wikipedia

    en.wikipedia.org/wiki/Natural_experiment

    This study was an example of a natural experiment, called a case-crossover experiment, where the exposure is removed for a time and then returned. The study also noted its own weaknesses which potentially suggest that the inability to control variables in natural experiments can impede investigators from drawing firm conclusions.' [12]

  4. Mesocosm - Wikipedia

    en.wikipedia.org/wiki/Mesocosm

    In contrast to laboratory experiments, mesocosm studies are normally conducted outdoors in order to incorporate natural variation (e.g., diel cycles). Mesocosm studies may be conducted in either an enclosure that is small enough that key variables can be brought under control or by field-collecting key components of the natural environment for ...

  5. Wildlife observation - Wikipedia

    en.wikipedia.org/wiki/Wildlife_observation

    Wildlife observation is the practice of noting the occurrence or abundance of animal species at a specific location and time, [1] either for research purposes or recreation. Common examples of this type of activity are bird watching and whale watching.

  6. Observational methods in psychology - Wikipedia

    en.wikipedia.org/wiki/Observational_Methods_in...

    This type of observation is useful because it allows observers to see how individuals act in natural settings, rather than in the more artificial setting of a lab or experiment. A natural setting can be defined as a place in which behavior ordinarily occurs and that has not been arranged specifically for the purpose of observing behavior. [2]

  7. Scientific method - Wikipedia

    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 ...

  9. Scientific law - Wikipedia

    en.wikipedia.org/wiki/Scientific_law

    Scientific laws or laws of science are statements, based on repeated experiments or observations, that describe or predict a range of natural phenomena. [1] The term law has diverse usage in many cases (approximate, accurate, broad, or narrow) across all fields of natural science (physics, chemistry, astronomy, geoscience, biology).
