Quizplus · Accepted Answer

The scenario describes the investigator intentionally manipulating a variable (subtracting two ounces of cleaning concentrate) to observe its effect on sales, which is the definition of experimental research. Survey research involves gathering data from a sample through questionnaires or interviews, secondary research involves analyzing existing data, and observation research involves observing and documenting natural behavior without manipulation.
