Question

Quizplus · Accepted Answer

Experiments allow for conclusions about cause and effect relationships because researchers manipulate one variable (independent variable) and observe its effects on the other variable (dependent variable) while controlling all other variables that might influence results. Through this manipulation and control, researchers can draw conclusions about the causal relationship between the independent and dependent variables. Options A, B, and D are important components of good experimental design but do not directly address the ability to draw conclusions about cause and effect relationships.
