Shortening the time between pretest and posttest or perhaps even offering cash payments to participants in an experiment are techniques that may be used to:
A) limit diffusion
B) decrease experimental mortality
C) decrease the effects of instrumentation
D) control threats to testing

Question

Quizplus · Accepted Answer

Shortening the time between pretest and posttest may not necessarily reduce experimental mortality. Additionally, offering cash payments would not necessarily control threats to testing or decrease the effects of instrumentation. However, offering cash payments may incentivize participants to remain in the study and reduce the likelihood of dropping out, thereby decreasing experimental mortality.
