You have been asked to see if wearing body cameras reduces complaints against police. Your hypothesis is that police who wear body cameras will have fewer complaints than those who don't. You test the program with the following research design.

E=equivalence

O=observation

X=treatment

(E) O1 X O2

(E) O3 O4

Using the research design above, X would be considered

a. A measure of internal validity

b. Body worn cameras

c. Crime rates

d. Police Attitudes

e. None of the above

Using the research design from the above question, if we assume the treatment will work as expected what predictions can you make about complaints?

a.O2 should be greater than O4 while O3 should be greater than O1

b.O4 should be less than O3 while O2 should be equal to O4

c.O2 and O4 should not change while O1 should be higher than O3

d.O2 should be less than O1 while O3 and O4 remain constant

e. cannot tell from the information given
