Which type of research is a logical and systematic way of answering the question 'If this is done under carefully controlled conditions, what will happen?'

• A. Action Research
• B. Historical Research
• C. Experimental and Quasi-Experimental Research
• D. Descriptive Research

Answer: (C)

This item tests understanding of research designs that test causality by manipulating a variable under carefully controlled conditions and observing the outcome. That setup is the hallmark of experimental research, and when random assignment isn’t possible, quasi-experimental designs are used to still compare groups under some level of control. Other approaches don’t involve this kind of deliberate manipulation under controlled conditions: action research focuses on improving practice in real settings; historical research looks at past events; descriptive research describes phenomena as they exist without testing specific causal effects. So the description points to Experimental and Quasi-Experimental Research.
