• constant.
• dependent variable.

A factor that changes in an experiment from manipulation of the independent variable is the

• hypothesis.
• control.
• constant.
• dependent variable.

A standard for comparison that helps to ensure that the experimental result is caused by the condition being tested is the 

• independent variable.
• dependent variable.
• constant.
• control.

When designing an experiment, the first step is to 

• analyze the data.
• state a hypothesis.
• state the problem.
• list a procedure.

A testable prediction is a(n)

• exercise.
• hypothesis.
• experiment.
• variable.
