Answer (1)
Experimental design is essential as it allows for control over variables, the ability to replicate studies, and minimizes bias through random assignment. These factors enable researchers to accurately determine cause-and-effect relationships in their studies. This approach is particularly useful in psychology to explore complex relationships, such as brain function in response to stimuli or personality traits related to interests. ;
