a systematic approach to researching questions and problems through objective and accurate observation, collection and analysis of data, direct experimentation, and replication of these procedures.
a source of knowledge based on the assumption that knowledge comes from the objective, systematic observation and measurement of particular variables and the events they affect. (35)
Identify and define a research problem Formulate hypotheses on the basis of theory, research, or both Design the research Conduct the research Analyze the data Interpret the data as they bear on the research question
a method of inquiry that involves ovservations, hypotheses and experiments to formulate theories.
The use of empirical data to test hypotheses derived from theory.
1.) make observations of available facts; 2.) develop a hypothesis; and 3.) test the hypothesis
A procedure used by scientists to test hypotheses by making predictions about the outcome of an experiment before the experiment is performed. The results provide support or refutation of the hypothesis.
A systematic way of solving a problem or answering a question using observation and measurement. The six steps of the scientific method are: state the problem, create a hypothesis, design an experiment, perform the experiment, organize and analyze the data, draw conclusions.
An iterative process in which a hypothesis is tested through experiments and compared to observation.
System of established principles and processes of scientific inquiry, including identification of a problem to be studied, formulation and testing of alternative hypotheses, collection and analysis of data, and public dissemination of findings so that other scientists can check, learn from, analyze, repeat, and build on the results.

How children put facts together to make sense of the world around them including observing, questioning, experimenting, manipulating, predicting and demonstrating understanding of concepts.
the process of studying natural phenomena, involving observations, forming laws and theories, and testing of theories by experimentation
A systematic approach involving recognition of a problem, formulation of a hypothesis, development of an experiment, observation and analysis of the results, and a conclusion that may reject or accept the hypothesis. More...
Pattern of reasoning used in the systematic search for knowledge. It involves identifying the problem, articulating a guiding hypothesis, obtaining evidence to test the hypothesis, and validating and explaining the significance of the hypothesis and the findings on which it rests.
The four-step method of inquiry preferred by scientists.
the approach taken by scientists to make observations of and theories about the world around them, and beyond. In essence it involves observing a phenomenon or group of phenomena in the universe; inventing a theory or hypothesis that is consistent with what's observed; using this hypothesis to make predictions; testing these predictions by experiments or further observations. Scientists then modify their theory in the light of their experimental results, and so on... The scientific method attempts to minimise the influence of the scientist's bias on the outcome of an experiment.
An inefficient but highly successful method of knowledge construction based on experimental testing of hypotheses.
orderly process by which theories are developed, tested, and either verified or disproved.
the principles and processes regarded as necessaryfor scientific investigation, including rules for concept or hypothesis formulation, conduct of experiments, and validation of hypotheses by analysis of observations.
a method of investigation involving observation and theory to test scientific hypotheses
a process of investigation that starts with a question and follows a set of repeatable steps to find an answer
Making observations and collecting data about natural events and conditions, then organizing and explaining them with hypotheses, theories, models, laws and principles.
A systematic approach to observing phenomena, drawing conclusions and testing hypotheses.
principles and procedures for the pursuit of knowledge. It includes a problem, the collection of data through observation and experiment, and the formulation and testing of hypotheses.
A systematic, precise, objective study of a problem. Generally this requires observation, hypothesis development and testing, data gathering, and interpretation.
The set of rules used to guide science, based on the idea that scientific "laws" be continuously tested, and replaced if found inadequate.
a process involving observation, repetition, and measurement in determining objective, true knowledge; involves gathering of data, formulation of hypotheses, and and empirical testing of the hypotheses, using the five senses.
Systematic apporach of observation, hypothesis formation, hypothesis testing and hypothesis evaluation that forms the basis for modern science.
A rational approach to explain natural events and processes by formulating, testing and modifying a hypothesis.
A process that is the basis for scientific inquiry. The scientific method follows a series of steps: (1) identify a problem you would like to solve, (2) formulate a hypothesis, (3) test the hypothesis, (4) collect and analyze the data, (5) make conclusions.
The systematic pursuit of knowledge involving the recognition and formulation of a problem, the collection of data through observation and experiment, and the formulation and testing of a hypothesis.
A sequence of steps for systematically analyzing scientific problems in a way that leads to verifiable results.
A logical progression of observation and analysis designed to solve a problem or answer a question. Involves formulation of a hypothesis, or educated guess, which is then tested for its ability to explain observed phenomena.
the step by step process by which scientists investigate hypotheses using experiments
a process of studying natural phenomena that involves making observations, forming laws and theories, and testing theories by experimentation.
A standardized way that scientists research and find answers to questions and problems.
the Koch-Henle Postulates first explained in the later 19th century; with respect to polio: to prove the role of the poliovirus in disease (the hypothesis), a researcher had to identify and isolate the alleged entity (poliovirus), grow it, infect an animal with it so that it produced the same symptoms (replicate results), and then recover the same entity from the diseased animal (verify results).
An objective method for evaluating questions of fact, premised on the belief that an original hypothesis may or may not be true; that such a hypothesis may be verified or disproved through a series of tests; and that the outcome of such tests should be conclusive in either direction because of the overall validation of information. The method has five steps: validation, hypothesis, prediction and testing.
The principles and empirical processes of discovery and demonstration considered characteristic of or necessary for scientific investigation, generally involving the observation of phenomena, the formulation of a hypothesis concerning the phenomena, experimentation to demonstrate the truth or falseness of the hypothesis, and a conclusion that validates or modifies the hypothesis.
"The totality of principles and processes regarded as characteristic or necessary for scientific investigation, generally taken to include rules for concept formation, conduct of observations and experiments, and validation of hypotheses by observation or experiments." (New American Heritage Dictionary) similar to the Shewhart Cycle.
A method of empirical inquiry involving prediction, observation, and experimentation (a framework of restraint).
The investigative technique used by all natural scientists throughout the world. In general, some data or ideas are first gathered, then a theory is proposed to explain them, and finally an controlled investigative experiment is devised to test the theory.
An organized approach devised by scientists for discovering causal relationships and testing the accuracy of conclusions.
Research method using experiments and physical evidence to answer questions about the natural world. ( learn more)
a systematic method of observation, experimentation, and analysis in order to construct an accurate representation of the world.
Scientific method is a body of techniques for investigating phenomena and acquiring new knowledge, as well as for correcting and integrating previous knowledge. It is based on gathering observable, empirical, measurable evidence, subject to the principles of reasoning.Isaac Newton (1687, 1713, 1726).
