Final answer:
An experimental study involves researchers creating conditions to establish cause-effect relationships by randomly assigning participants to groups.
Step-by-step explanation:
An experimental study refers to studies in which researchers create conditions to establish cause-effect relationships in which participants are randomly assigned to their respective groups.
This type of study involves manipulating an independent variable and measuring its effect on a dependent variable.
By randomly assigning participants to different groups, researchers can ensure that differences in the outcomes are a direct result of the different treatments.
