3. How can an experimenter verify the results of his experiment?
I. Repeating the experiment using the same procedure and conditions.
II. Performing similar experiment by the same person or by another experimenter.
III. Recommending the experiment for further study or improvements.
IV. Communicating or presenting the results to others.
A. I, II and III C. II, III, and IV
B. I, III and IV D. I, II, III, and IV
4. How does an independent variable differ from dependent variable?
A. An independent variable is a factor that is changed in the experiment while the dependent
variable is something that responds to the change; measured in the experiment.
B. A dependent variable is a factor that is changed in the experiment while an independent
variable is something that responds to the change; measured in the experiment.
C. All other factors that are kept constant or unchanged during the experiment are called
dependent variables while independent variables are variables that are changed in the
experiment.
D. Independent variable refers to the factor that depends on one material present in the
experiment while dependent variable is a factor that affects the other variables under study.
5. What should be done when the results of the experiment do not support the hypothesis?
I. Repeat the experiment and stick with your original hypothesis.
II. Formulate another hypothesis based on the information obtained from the experiment
then perform the experiment with similar conditions.
III. Stop performing the experiment.
IV. Identify different problem and perform different experiment.
A. I only B. II only C. III only D. IV only
