Research that explores cause and effect relationships by manipulating data is known as "experimental".

Experimental research is any research directed with a logical methodology, where an arrangement of variables are kept consistent while the other arrangement of factors are being estimated as the subject of test.  

A true experimental research is viewed as successful just when the scientist affirms that an adjustment in the reliant variable is exclusively because of the control of the independent variable.
