Experimental research designs are those designs that allocate the use of and methodology of manipulating the independent variables on some subject matter, or aspect that is being studied, and then carefully observing the results of this manipulation, in reference to its effects on the dependent variable within a given research data set. One type of independent variable manipulation that can be used, is the manipulation of the span of time that the independent variables interacts with the dependent variable, how frequently ...
