An experiment is direct observation under controlled conditions. Most experiments involve carefully changing one variable and observing the effect on another variable (for example, changing temperatur [..]

An experiment is a situation involving chance or probability that leads to results called outcomes.

late 15c., from experiment (n.). Intransitive sense by 1787. Related: Experimented; experimenting.

A scientific investigation in which an investigator manipulates and controls one or more independent variables and observes the dependent variable for variation concomitant to the manipulation of the independent variable(s).

to try or test an idea.

An effort to discover or confirm some principle or effect usually in some scaled down form such as a mockup, or surrogate form such as a computer model. [D02748]

an empirical study designed to relate cause and effect by ruling out as many alternative causes as possible and by actually manipulating the cause to obtain the effect, as opposed to merely finding a [..]

A set of controlled procedures designed to test an idea or hypothesis. For example, a flight simulation engineer will design an experiment to test whether or not a pilot can control an airplane with a new wing design.

What distinguishes an experiment from an observational study is that in an experiment, the experimenter decides who receives the treatment.

something tried out to see what will happen; a test to find out something

A scientific test that involves manipulating some factor or factors in a system in order to see how those changes affect the outcome or behavior of the system. Experiments are important in science, bu [..]

A research method in which variables can be analyzed under carefully controlled conditions--usually within an artificial situation constructed by the researcher—that can potentially determine whether a given variable affects another independently of other factors.

An artificially created situation that is used to test a hypothesis. In a controlled experiment, additional variables that might affect the experiment are prevented from doing so. experimental design

The series of observations under controlled conditions used to study relationships to draw a causal inference.

One type of research method in which the investigator manipulates one or more independent variables (IV) to determine the effect(s) on some behavior (the dependent variable) while controlling other re [..]

an empirical research method used to examine a hypothesised causal relationship between independent and dependent variables.

An observation of natural phenomena carried out in a controlled manner so that the results can be duplicated.

A research study in which the independent variables are manipulated and subjects are randomly assigned to different conditions.

A test or trial used to gain knowledge or to test a theory.

To try several different or new ways to discover something unknown or to demonstrate something known.

An experiement is a procedures in which all the relevant variables are manipulaed by the experimenter in a controlled environment, which excludes any other variables that may effect the outcome.

A carefully controlled situation where the independent variable is manipulated while everything else remains the same; the aim is to see whether the dependent variable will change.

An experiment is any study in which the conditions are under the direct control of the researcher. This usually involves giving a group of people an intervention that would not have occurred naturally. Experiments are often used to test the effects of a treatment in people and usually involve comparison with a group who do not get the treatment.

A formal method used in empirical research.

The process of making an observation or taking a measurement.

A controlled environment for the application of common sense. Having observed something interesting in the world of chemistry, we make an educated guess as to what is happening (a 'theory'), then say "if this explanation is true, we should see such-and-such an effect if we do such-and-such." Actually doing such-and-such and seei [..]

In general terms, the word “experiment” can simply designate a new idea about how to do something.  In formal social science or medical research, “experiment” has a very specific meaning, in which a t [..]

In probability, a general term used to denote an event whose outcome is uncertain. In econometric analysis, it denotes a situation where data are collected by randomly assigning individuals to control and treatment groups.

A type of research in which one or more elements of a retail strategy mix are manipulated under controlled conditions.
