RESEARCH METHODOLOGY

Detailed explanation-1: -The True Experiment: A research method in which an investigator manipulates one or more factors (independent variables) in order to observe the effect on some behavior or mental process (dependent variable).

Detailed explanation-2: -An experiment is a type of empirical study that features the manipulation of an independent variable, the measurement of a dependent variable, and control of extraneous variables.

Detailed explanation-3: -Experimental manipulation describes the process by which researchers purposefully change, alter, or influence the independent variables (IVs), which are also called treatment variables or factors, in an experimental research design.

Detailed explanation-4: -Experimental research is a kind of study that rigidly follows a scientific research design. It involves testing or attempting to prove a hypothesis by way of experimentation. As such, it uses one or more independent variables, manipulating them and then using them on one or more dependent variables.

Detailed explanation-5: -It was stated in Chapter 2 that an experiment is “a research method in which the investigator manipulates a variable under carefully controlled conditions and observes whether any changes occur in a second variable as a result” (p. 42).
