Answer to Question 1

c

Answer to Question 2

There are essentially two variations of this design. In the first, you ask the participants to estimate where their pretest level would have been. This can be called the Recollection or Retrospective designparticipants are literally asked to look back.. For instance, you might ask participants to complete pretest measures by estimating how they would have answered the questions six months ago.
The other Proxy-Pretest design uses archived records to stand in for the pretest. This design is called the Archived Proxy-Pretest design. For instance, imagine that you are studying the effects of an educational program on the math performance of eighth-graders. Unfortunately, you were brought in to do the study after the program had already been started. You are able to collect a posttest that shows math ability after training, but you have no pretest. Under these circumstances, your best bet might be to find a proxy variable from existing records that would estimate pretest performance. For instance, you might use the students' grade-point averages in math from the seventh grade as the proxy-pretest.
