What are the two general methods to assess behavioral changes?
Qualitative and Quantitative
External and Internal
Indirect and Direct measurement
Experimental and Observational
The correct answer is: Indirect and Direct measurement
Indirect and direct measurement are the two general methods to assess behavioral changes. Qualitative and quantitative methods focus on the type and amount of data collected, rather than the method of measurement. External and internal methods focus on the source of the data. Experimental and observational methods focus on the experimental design, rather than the type of data collected. Therefore, A, B, and D are incorrect and do not accurately answer the question.
