Experimental research

Experimental research designs are used for the controlled testing of causal processes. The general procedure is one or more independent variables are manipulated to determine their effect on a dependent variable.
These designs can be used where:
1. There is time priority in a causal relationship (cause precedes effect),
2. There is consistency in a causal relationship (a cause will always lead to the same effect), and
3. The magnitude of the correlation is great.
Experiments are conducted to be able to predict phenomenons. Typically, an experiment is constructed to be able to explain some kind of causation. Experimental research is important to society – it helps us to improve our everyday lives.
