However, by observing various clouds of hydrogen in various states of collapse, and other implications of the hypothesis for example, the presence of various spectral emissions from the light of stars , we can collect data we require to support the hypothesis.

An early example of this type of experiment was the first verification in the 17th century that light does not travel from place to place instantaneously, but instead has a measurable speed.

Observation of the appearance of the moons of Jupiter were slightly delayed when Jupiter was farther from Earth, as opposed to when Jupiter was closer to Earth; and this phenomenon was used to demonstrate that the difference in the time of appearance of the moons was consistent with a measurable speed.

Field experiments are so named to distinguish them from laboratory experiments, which enforce scientific control by testing a hypothesis in the artificial and highly controlled setting of a laboratory.

Often used in the social sciences, and especially in economic analyses of education and health interventions, field experiments have the advantage that outcomes are observed in a natural setting rather than in a contrived laboratory environment.

For this reason, field experiments are sometimes seen as having higher external validity than laboratory experiments. However, like natural experiments, field experiments suffer from the possibility of contamination: experimental conditions can be controlled with more precision and certainty in the lab.

Yet some phenomena e. An observational study is used when it is impractical, unethical, cost-prohibitive or otherwise inefficient to fit a physical or social system into a laboratory setting, to completely control confounding factors, or to apply random assignment.

It can also be used when confounding factors are either limited or known well enough to analyze the data in light of them though this may be rare when social phenomena are under examination.

For an observational science to be valid, the experimenter must know and account for confounding factors.

In these situations, observational studies have value because they often suggest hypotheses that can be tested with randomized experiments or by collecting fresh data.

Fundamentally, however, observational studies are not experiments. By definition, observational studies lack the manipulation required for Baconian experiments.

In addition, observational studies e. Observational studies are limited because they lack the statistical properties of randomized experiments.

In a randomized experiment, the method of randomization specified in the experimental protocol guides the statistical analysis, which is usually specified also by the experimental protocol.

For example, epidemiological studies of colon cancer consistently show beneficial correlations with broccoli consumption, while experiments find no benefit.

A particular problem with observational studies involving human subjects is the great difficulty attaining fair comparisons between treatments or exposures , because such studies are prone to selection bias , and groups receiving different treatments exposures may differ greatly according to their covariates age, height, weight, medications, exercise, nutritional status, ethnicity, family medical history, etc.

In contrast, randomization implies that for each covariate, the mean for each group is expected to be the same. For any randomized trial, some variation from the mean is expected, of course, but the randomization ensures that the experimental groups have mean values that are close, due to the central limit theorem and Markov's inequality.

With inadequate randomization or low sample size, the systematic variation in covariates between the treatment groups or exposure groups makes it difficult to separate the effect of the treatment exposure from the effects of the other covariates, most of which have not been measured.

The mathematical models used to analyze such data must consider each differing covariate if measured , and results are not meaningful if a covariate is neither randomized nor included in the model.

To avoid conditions that render an experiment far less useful, physicians conducting medical trials—say for U.

Food and Drug Administration approval—quantify and randomize the covariates that can be identified. Researchers attempt to reduce the biases of observational studies with matching methods such as propensity score matching , which require large populations of subjects and extensive information on covariates.

However, propensity score matching is no longer recommended as a technique because it can increase, rather than decrease, bias.

In this way, the design of an observational study can render the results more objective and therefore, more convincing.

By placing the distribution of the independent variable s under the control of the researcher, an experiment—particularly when it involves human subjects —introduces potential ethical considerations, such as balancing benefit and harm, fairly distributing interventions e.

For example, in psychology or health care, it is unethical to provide a substandard treatment to patients. Therefore, ethical review boards are supposed to stop clinical trials and other experiments unless a new treatment is believed to offer benefits as good as current best practice.

To understand the effects of such exposures, scientists sometimes use observational studies to understand the effects of those factors.

Even when experimental research does not directly involve human subjects, it may still present ethical concerns. For example, the nuclear bomb experiments conducted by the Manhattan Project implied the use of nuclear reactions to harm human beings even though the experiments did not directly involve any human subjects.
