Explanation / Answer

Answer 7: examining relationships among variables (As explained below)

Correlational method is a statistical method which measures the extent to which two variables are related. Experimental research allows for verifying the cause-and-effect relationship between variables. Collecting data through interviews and questionnaires can be referred to as surveying. Examining of single individual in detail can be referred to as profiling.

Answer 8: experimental study (As explained below)

Since the researcher Dr. James has control over the variables (facial symmetry), it cannot be observational study. Observational studies are those in which researcher does not control the variables. It cannot be naturalistic because the setup is not natural and there is substantial interference with the subjects or occurrence (varying facial symmetry). The study can be said to be experimental because the setup over which the result produced is intentional.

Answer 9: Random assignment (As explained below)

Random sampling means population is selected and sorted into groups using a random procedure. Random assignment, on the other hand, specifically means assigning to treatment or control group using a random procedure. In a single-blind study the participants do not know whether they are part of the experimental group or the control group. In the double-blind study, both the researcher as well as the participants do not know which group the participants belong.
