Question

the dependent variable:
○ must be testable.
○ is the group that does receives the treatment being studied.
○ is the condition that the researcher manipulates.
○ is the group that receives the placebo.
○ is what a researcher is going to measure.

Explanation:

To determine the correct option for the dependent variable:

• "Must be testable" refers to hypotheses, not dependent variables.
• "Is the group that does receives the treatment being studied" describes the experimental group, not a variable.
• "Is the condition that the researcher manipulates" describes the independent variable.
• "Is the group that receives the placebo" describes the control group, not a variable.
• "Is what a researcher is going to measure" matches the definition of a dependent variable (it depends on the independent variable and is measured in an experiment).

Answer:

Is what a researcher is going to measure.
