Question

A graduate student randomly assigns students in a class to taste either Coke or Pepsi. Students rate their liking for the soda on a scale from 1 to 10. This is an example of a ________ design.

A.
posttest-only


B.
pretest only


C.
non-experimental

D.
one-group pretest-posttest

Answer 1

A.  Post-test only

Students are not being tested before drinking the soda. So it does not include a Pre-test, ruling out B and D.

Its not "non-experimental" because that involves unobtrusive observation....which this is NOT.
