This is an example of experimental research, as Ann has divided her participants into two groups and is manipulating a variable (teaching method) to see if it has an effect on the outcome (subtraction skills). Quasi-experimental research may not involve random assignment to groups and historical research looks at past events rather than testing a hypothesis. Correlational research examines the relationship between variables without manipulating them.
