Quizplus · Accepted Answer

The measurement of social anxiety on Monday is the pretest, which is done before the intervention (yoga instruction) and serves as a baseline measurement to compare to the posttest on Friday. The independent variable is the instruction in yoga, the control group would be a group that did not receive yoga instruction, and the dependent variable is the measurement of social anxiety on Friday.
