Questions below are based on the following simulation: A researcher attempted to discover if the amount of learned material retained by first-grade children was a function of the mode by which the material was presented. Two first-grade classes are selected, Miss Emily McKenna's class and 142 Miss Clair Keating's class. The study began at 9 AM on a Monday morning. By a flip of a coin, Mrs. Vivian's class was chosen to receive a visual presentation, whereas in Miss McKenna's class an auditory presentation of the same material was used. One hour later, the two groups were compared regarding the amount of material that was retained.
-The research procedure in this case illustrates the
A) quasi-experimental method.
B) post-facto method.
C) repeated-measures method.
D) true experiment.

The quasi-experimental method is a research design that is used when the researcher does not have control over the assignment of participants to groups. In this case, the researcher flipped a coin to assign the classes to the visual and auditory presentation groups. This means that the researcher did not have control over which group received which presentation, so the design is quasi-experimental.
