Research variables

In every scientific investigation, there are different variables. These include:

  • Independent variables: These are the variables that are supplied by the researcher and often varied to produce different effects. It is often referred to as the 'cause' variable.
  • Dependent variables: These are variables that are measured in the course of research. They are a result of the effects of the independent variable on the experimental subjects or groups. They are otherwise known as 'effect' variables.
  • Constant variables: Variables that are applicable to all experimental groups and are usually kept constant.

Also, there are different groups in research:

  • Control group: The reference group. The group that is not fed with the independent variable and forms the basis for comparison in order to understand the effects of the independent variable.
  • The experimental group: The group that is fed with the independent variable.
