What are the three principles of experimentation?

There are three basic principles behind any experimental design:

Randomisation: the random allocation of treatments to the experimental units.
Replication: the repetition of a treatment within an experiment allows:
Reduce noise: by controlling as much as possible the conditions in the experiment.

What are the two groups in experimental design?

The two groups usually consist of a control group, who does not get the treatment, and a treatment or experimental group, who does get the treatment. In order to assign subjects to groups, researchers have two options.

What are the main components of experimental design?

What are the features of experimental design?

Several kinds of experimental designs exist. In general, designs that are true experiments contain three key features: independent and dependent variables, pretesting and posttesting, and experimental and control groups. In a true experiment, the effect of an intervention is tested by comparing two groups.

What is replication in an experiment?

In statistics, replication is repetition of an experiment or observation in the same or similar conditions. Replication is important because it adds information about the reliability of the conclusions or estimates to be drawn from the data.
