the manipulated variable is often called the variable.

a manipulated variable always has more than one level or -- and is altered to see if it will result in a change in the variable, which is typically measured.

When researchers manipulate a variable in a study, that study is typically referred to as a(n) experiment.

The manipulated variable is often called the independent variable.

A manipulated variable always has more than one level or condition and is altered to see if it will result in a change in the dependent variable, which is typically measured.

Explanation:

An experiment involves procedures conducted to proof or disproof a hypothesis. Method of conducting research is different depending on the experiment itself or the field of study/research. The researchers may set parameters of the experiment and this is done by manipulating independent variables.

An independent variable can be changed as the researcher pleases to check the effect of the dependent variable. Therefore the dependent variable is determined during the experience. Conditions will also depend on the researcher and the dimension of the research. It can also be manipulated as one pleases.
