Detailed explanation-1: -Experimental research involves the manipulation of an independent variable and the measurement of a dependent variable. Random assignment to conditions is normally used to create initial equivalence between the groups, allowing researchers to draw causal conclusions.

Detailed explanation-2: -Experiment: A research method in which an investigator manipulates one or more factors (independent variables) to observe the effect on some behavior or mental process (the dependent variable). Experiments use random assignment of participants to control other relevant factors.

Detailed explanation-3: -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-4: -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-5: -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.
