Certain dependent variables, such as solving puzzdes and completing mazes, are difficult to administer more than once. For these research projects, researchers typically avoid which kind of design? a matched pairs b. repeated measures c. between-subjects d. natural pairs 4. Which of the following is a limitation of the ex post facto design? Participants who are exposed to the DV multiple times can become sensitized to the area under investigation Experimenter bias is a greater problem in ex post facto research compared with other research designs a. b. c. It is difficult to find natural pairs d. You cannot be certain that the IV is the only difference between groups 5. Julie measures participants' anxiety levels before treatment and again after treatment. Julie is search o eExplanation / Answer
