1.
(a) what specific quasi-experimental design was used in this study?
(b) explain why you classified it as you did.
2.
(a)ldentify two (plausible) threats in general to the internal validity of this type of design.
(b) then, indicate how these two threats might operate in this particular situation. That is, speculate on ways that the threats which you have identified might operate given what you know about the method and measures used by Tylor (1998). (keep in mind that the two groups were shown not to differ initially on certain relevant characteristics.)
4 the author did not find a significant difference overall between the two groups for measures of ”reality shock”(e.g., confidence in work preparation or anxiety). Ldentify one possible reason no difference was found in terms of both the measures used and the nature of the participants tested.
5 ldentify two questions of external validity which an investigator might want to address in future research.
