Question

Which TWO terms listed below are most descriptive of an observational design?

1) Experimental and control groups
2) Independent and dependent variables
3) Random assignment and manipulation
4) Observing and recording behavior
5) Qualitative and quantitative data

Answer 1

The terms 'observing and recording behavior' and 'qualitative and quantitative data' are most descriptive of an observational design, as they involve non-interventional data collection about naturally occurring phenomena.

Step-by-step explanation:

The two terms most descriptive of an observational design are observing and recording behavior and qualitative and quantitative data. In an observational study, researchers do not intervene or manipulate the setting or subjects; they simply observe and record what occurs. This approach can include both qualitative data, which is descriptive and concerns properties that are not numerical, and quantitative data, which can be measured and expressed numerically. Observational designs are distinct from experimental research, where researchers would manipulate variables, use control and experimental groups, and handle the assignment of subjects randomly.
