Answer:
Independent Variable: Hours of sleep
Dependent Variable: Test scores
Experimental Group: Group A
Control Group: Group B
Explanation:
Hours of sleep is the independant variable because it is the factor being tested by the teacher. This is the factor that can be controlled.
Test scores is the dependant variable because it is the factor being affected by the changes in the independent variable. This is the variable being measured.
Group A is the experimental group because this is the one that has been altered or changed from what is normal.
Group B is the control group because nothing is being changed in this group but simply measured as a basis for comparison.
