What is the goal of experimental research?

1. To explain behavior

2. To establish a causal relationship

3. To gain insight into a particular population

4. To obtain an accurate assessment

The correct answer is: To establish a causal relationship

Experimental research is a scientifically rigorous approach to studying cause and effect relationships between variables. The goal of experimental research is to determine whether changes in one variable directly cause changes in another variable. This is achieved through manipulating one variable and measuring the corresponding changes in the other variable. Therefore, the goal of experimental research is not simply to explain behavior (option A), gain insight into a particular population (option C), or obtain an accurate assessment (option D). While these may be potential outcomes of experimental research, they are not the primary goal. The goal is to determine causality and establish a causal relationship (option B) between variables, which is achieved through careful experimental design and control.
