What is a well tested explanation supported by many observations?

What is a well tested explanation supported by many observations?

A scientific theory is a well-tested explanation for a wide range of observations or experimental results.

What is an explanation of observations that have been tested many times?

A scientific theory is an explanation of an aspect of the natural world and universe that has been repeatedly tested and verified in accordance with the scientific method, using accepted protocols of observation, measurement, and evaluation of results.

How many variables are in a controlled experiment?

A controlled experiment requires at least two variables: a manipulated variable and a response variable.

What is a proposed explanation for a set of observations that is also testable by an experiment?

An hypothesis is a proposed explanation for a set of observations, a phenomenon. Scientific hypotheses must satisfy a defining criterion: that they be testable . In other words there must be an experiment that can be performed which supports or undermines the hypothesis.

What is a possible explanation for an observation that can be tested?

hypothesis. a possible explanation for an observation that can be tested by scientific investigations. prediction. a statement of what will happen next in a sequence of events. scientific theory.

What is an explanation for an observation?

An hypothesis is a proposed explanation for a set of observations, a phenomenon. Scientific hypotheses must satisfy a defining criterion: that they be testable . If the results support the hypothesis, then the hypothesis is a useful basis for further experiments.

What is a well tested explanation?

A Theory is a well-tested explanation for a wide range of observations or experimental results.

What is tested in a controlled experiment?

In a controlled experiment, an independent variable (the cause) is systematically manipulated and the dependent variable (the effect) is measured; any extraneous variables are controlled. The quantitative data can be analysed to see if there is a difference between the experimental group and control group.

What is a proposed explanation for an association and must be tested?

hypothesis. a proposed explanation for a set of observations.

What is a possible explanation called?

An hypothesis (plural, hypotheses ) is a proposed explanation for a given set of facts or observations.

What is an explanation of an observation?

Observation is the active acquisition of information from a primary source. In living beings, observation employs the senses. In science, observation can also involve the perception and recording of data via the use of scientific instruments. The term may also refer to any data collected during the scientific activity.

What does a theory explain?

A theory is a well-substantiated explanation of an aspect of the natural world that can incorporate laws, hypotheses and facts. A theory not only explains known facts; it also allows scientists to make predictions of what they should observe if a theory is true. Scientific theories are testable.
