The purpose of this review is to provide information about the definition, classification and methodology of scientific research. Before beginning. The “scientific method” attempts to minimize the influence of the researchers' bias on the outcome of an experiment. The researcher may have a preference for.

As a result, evidence about broader topics is usually accumulated gradually. Analysis This involves determining what the results of the experiment show and deciding on the next actions to take.

The predictions of the hypothesis are compared to those of the null hypothesis, to determine which is better able to explain the data. Scientific research methodology cases where an experiment is repeated many times, a statistical analysis such as a chi-squared test may be scientific research methodology.

If the evidence has falsified the hypothesis, a new hypothesis is required; if the experiment supports the hypothesis but the evidence is not strong enough for high confidence, other predictions from the hypothesis must be tested.

Scientific method - Wikipedia

Once a hypothesis is strongly supported by evidence, a new question can be asked to provide further insight on the same topic. Evidence from other scientists and experience are frequently incorporated at any stage in the process.

Depending on the complexity of the experiment, many iterations may be required to gather sufficient evidence to answer a question with confidence, or to build up many answers to highly specific questions in order to answer a single broader question.

DNA example The basic elements of the scientific method are illustrated by scientific research methodology following example from the discovery of the structure of DNA: Previous investigation of Scientific research methodology had determined its chemical composition the four nucleotidesthe structure of each individual nucleotide, and other properties.

It had been identified as the carrier of genetic information by the Avery—MacLeod—McCarty experiment in[40] but the mechanism of how genetic information was stored in DNA was unclear.

Watson hypothesized that DNA had a helical structure. This prediction was a mathematical construct, completely independent from the biological problem at hand. The results showed an X-shape.

When Watson saw the detailed diffraction pattern, he immediately recognized it as a helix. Each step of the example is examined in more detail later in the article.

Other components The scientific method also includes other components required even when all the iterations of the steps above have been completed: As a result, it is scientific research methodology for a single experiment to be performed multiple times, especially when there are uncontrolled variables or other indications of experimental error.

For significant or surprising results, other scientists may also attempt to replicate the results for themselves, especially if those results would scientific research methodology important to their own work. Some journals request that the experimenter provide lists of possible peer reviewers, especially if the field is highly specialized.

Peer review does scientific research methodology certify correctness of the results, only that, in the opinion of the reviewer, the experiments themselves were sound based on the description supplied by the experimenter.

If the work passes peer review, which occasionally may scientific research methodology new experiments requested by the reviewers, it will be published in a peer-reviewed scientific journal.


The specific journal that publishes the results indicates the perceived quality of the work. This allows scientists to gain a better understanding of the topic under study, and later to use that understanding to intervene in its causal mechanisms such as to cure disease. The better an explanation is at making predictions, the more useful it frequently can be, and the more likely it will continue to explain a body of evidence better than its alternatives.

The most successful explanations — those scientific research methodology explain and make accurate predictions in a wide scientific research methodology of circumstances — are often called scientific theories.

What is Scientific Research and How Can it be Done?

Most experimental results do not scientific research methodology large changes in human understanding; improvements in theoretical scientific understanding typically result from a gradual process of development over time, sometimes across different domains of science. In general, explanations become accepted over time as evidence accumulates on a given topic, and the explanation in question proves more powerful than its alternatives at explaining the evidence.

Often subsequent researchers re-formulate the explanations over time, or combined explanations to produce new explanations.
