Which best describes the scientific process
olya-2409 [2.1K]

Answer:

The scientific method is a methodology to obtain new knowledge, which has historically characterized science, and which consists of systematic observation, measurement, experimentation, and the formulation, analysis and modification of hypotheses.

Explanation:

The main characteristics of a valid scientific method are falsifiability, and the reproducibility and repeatability of the results, corroborated by peer review. Some types of techniques or methodologies used are deduction, induction, abduction, and prediction, among others.

The scientific method encompasses the practices accepted by the scientific community as valid at the time of exposing and confirming their theories. The rules and principles of the scientific method seek to minimize the influence of the subjectivity of the scientist in his work, thus reinforcing the validity of the results, and therefore, of the knowledge obtained.
