	Experiment - Wikipedia, the free encyclopedia
		In the [scientific method], an experiment ([Latin]: ex-+-periri, "of (or from) trying"), is a set of actions and observations, performed in the context of solving a particular problem or question, to support or falsify a hypothesis or research concerning phenomena.
		In human experiments, a subject (person) may be given a stimulus to which he or she should respond.
		The goal of the experiment is to measure the response to a given stimulus.

	Introduction to the Scientific Method
		The scientific method is the process by which scientists, collectively and over time, endeavor to construct an accurate (that is, reliable, consistent and non-arbitrary) representation of the world.
		Experiments may test the theory directly (for example, the observation of a new particle) or may test for consequences derived from the theory using mathematics and logic (the rate of a radioactive decay process requiring the existence of the new particle).
		Since this is the domain of a large portion of human experience, the laws of classical mechanics are widely, usefully and correctly applied in a large range of technological and scientific problems.

	PowerPedia:Experiment - PESWiki
		An experiment, in the scientific method, is a set of actions and observations which is performed to verify or falsify a hypothesis or identify a causal relationship between phenomena.
		Analysis of the design of experiments was built on the foundation of the analysis of variance, a collection of models in which the observed variance is partitioned into components due to different factors which are estimated and/or tested.
		To demonstrate a cause and effect hypothesis, an experiment must often show that a phenomenon occurs after a certain treatment is given to a subject, and that the phenomenon does not occur in the absence of the treatment.

	Dummies::Designing Experiments Using the Scientific Method
		Experiments must have the ability to be duplicated because the "answers" the scientist comes up with (whether it supports or refutes the original hypothesis) cannot become part of the knowledge base unless other scientists can perform the exact same experiment(s) and achieve the same result; otherwise, the experiment is useless.
		If an experiment is performed repeatedly and the results are within a narrow margin, the results are said to be significant when measured using the branch of mathematics called statistics.
		The independent variable from each experiment is plotted on the x-axis (the one that runs horizontally), and the dependent variable is plotted on the y-axis (the one that runs vertically).

	THE SCIENTIFIC ...
		That is, other researchers must be able to repeat the experiment under the same conditions and achieve the same results.
		This requires publication, in appropriate scientific literature, of a detailed report of the problem, the hypothesis, all experimental methods and results, and the conclusions reached by the investigator.
		The scientific method is nothing more than a logical and reliable method used to determine the truth or solve problems.

	Pahnke's "Good Friday Experiment" - Follow-up
		Describing the experiment, Walter Houston Clark, 1961 recipient of the American Psychological Association's William James Memorial Award for contributions to the psychology of religion, writes, "There are no experiments known to me in the history of the scientific study of religion better designed or clearer in their conclusions than this one" (Clark, 1969, p.
		On the morning of the experiment, a helper who did not participate further in the experiment and who did not know any of the subjects, flipped a coin to determine to which group, psilocybin or placebo, each member of the pair would be assigned.
		This experience of a powerful loss of the usual sense of self and identity would be highly correlated with mystical experience in the questionnaire but may not actually be related because it can occur for a variety of reasons.

		Design an experiment to determine if there is any difference in the number and types of organisms caught in the grass on the north, east, west, and south side of the school building.
		However, from your experiments, you may be able to infer as to whether temperature has any impact on the number and variety of animals collected.
		The reporting form for this experiment is set up so that you can determine how many sweeps you want to conduct, where you want to do the sweeps, and the times that you want to sweep.

	Jacket 20 - Kate Price: Experiment magazine, 1928-31
		The ethical burden of literary experiment was first aired by Bronowski in his analytic essay on ‘Symbolism’, in which he argued that a work may take on moral significance in two ways: by means of imagery or symbolism.
		The theme of death pervades the second number of Experiment, while resurrection creeps into the third number, indicating the effect of autumn and spring on the writers and serving as a reminder of the immediacy with which the magazine was assembled.
		Experiment contributed thirty-two pages of material to a special issue of transition in June 1930, and in Spring the following year the magazine was relaunched as The New Experiment, distributed by William Heinemann, with a new cover design and a price increase from one and six to two shillings.

		A discussion of an experiment on 'intelligent design' and some photographic evidence for the progress of the experiment.
		That science regards the question of the existence of God to be a question for 'metaphysics' is therefore evidence for an a priori assumption that God does not exist and is evidence then for the existence of bias on the part of scientists.
		I offer a final prediction, which is that while the understanding of DNA is in its infancy, as time goes on it should be possible for understanding to grow of the nature of the biological algorithms encoded in DNA which are responsible for both directed evolution and spontaneous remission of fatal illness.

		Overview: I hope this lecture shows you that the scientific method is not as impersonal and dry as it sometimes appears.
		You will learn where scientific questions come from, and begin to appreciate the motivations of scientists who are interested in the biological bases of behaviour.
		Therefore we will examine an example of a ground breaking series of experiments involving an animal model of Parkinson's disease which offer the hope for a new form of treatment involving tissue transplantation into a part of the patient's brain that is affected by the disease.

		So Adam and Eve became the first humans to conduct a "scientific experiment." They observed and saw that the tree appeared to be good for food.
		For this reason, the usual methods of scientific proof involving experiments that can be repeated and mathematically analyzed are not applicable" (Essentials of Earth History, by William Stokes, 1960, p 5).

		They do experiments or scientific tests to examine which variables are most sensitive to changes and to test ideas, and they analyze their experimental results to solve the problem and find out what causes the action.
		This is in contrast to the experiments of physicists, chemists, or psychologists, who conduct controlled experiments that allow them to investigate the effects of different parameters by varying each parameter separately while holding all other factors constant.
		A scientific theory that has finally been accepted has gone through many iterations of model construction and prediction, followed by data collection and model refinement, until all aspects of the theory are repeatable.

	The Rolling Ball Web - Scientific and Scientific Demonstration Apparatus
		The distinction between the use of a rolling ball in an actual scientific experiment and its use in a salon or classroom demonstration device is difficult.
		In part, this is because the use of rolling balls in science predates the establishment of modern criteria for experiment.
		The demonstration of scientific and mechanical principles by means of lectures accompanied by demonstration apparatus reached a high point in the 18th.
