Question

TRUE / FALSE to the questions below

11.           In basic experimental designs, the interaction of two independent variables can be

                studied.

12.           Field experiments are conducted in laboratory settings.

13.           External validity has to do with the determination of whether the independent variable

                was the sole cause of the changes in the dependent variable.

14.           A major advantage of the static group design is that we have some assurance that the

15.           The effect of testing can only occur in "before‑after" experiments.
