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). By randomly assigning participants to groups, other relevant factors are controlled.

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 research is a scientific approach to research, where one or more independent variables are manipulated and applied to one or more dependent variables to measure their effect on the latter.

Detailed explanation-4: -In the experimental method of research, the independent variable is manipulated to observe and measure its effect on the dependent variable. Experimental Method: Experimental research is research conducted with a scientific approach using two sets of variables.

Detailed explanation-5: -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.
