____________ is a type of investigation carried out scientifically utilizing two or more variables?
Show answer Hide answer
Answer: A. Experimental research
Explanation
Experimental research involves scientific investigation utilizing two or more variables under controlled conditions. Researchers actively manipulate an independent variable to observe its direct effect on a dependent variable. Establishing cause and effect relationships requires the rigorous variable control inherent in experimental research. True experiments require random assignment, manipulation of variables, and tight control of extraneous factors. Variables in experiments are clearly operationalized so other scientists can replicate the study successfully. Statistical tests are applied to experimental data to determine if observed differences are statistically significant.
Agronomists test how different amounts of fertilizer impact crop yield using experimental research designs. Psychologists study memory retention by exposing different participant groups to varying memorization techniques. Pharmaceutical companies conduct experimental research to test drug dosages on human biological systems. Historical Research examines past events and does not involve manipulating active variables in real time. Applied research solves practical problems but does not automatically imply the variable manipulation of experiments. Basic research expands fundamental knowledge without necessarily focusing on experimental variable manipulation.
