Hard
A.Nationwide adoption should proceed only after every institution has employed staff with exactly the same experience as the pilot team
B.The pilot failed because its staff were not representative of national conditions
C.The result is promising, but its generalizability must be tested before expansion
D.The reduction in waiting time is invalid because the sample was small
Correct Answer: The result is promising, but its generalizability must be tested before expansion

Hard
A.The theory is attractive in structure but remains empirically under-supported
B.The theory is simple but irrelevant because none of its assumptions is logical
C.The theory is concise and definitively confirmed by the available evidence

49In an argument, the author writes: "Attendance rose after recorded lectures were introduced. Yet examination performance remained stable, suggesting that access and learning outcomes should not be treated as interchangeable." What implicit assumption does the conclusion require?
Understanding the text
Hard
A.Attendance figures measure student access more accurately than every alternative measure used across educational research
B.Stable examination scores prove that no individual student learned more
C.Examination performance is at least a relevant indicator of learning outcomes
D.Recorded lectures are the only possible cause of increased attendance
Correct Answer: Examination performance is at least a relevant indicator of learning outcomes
Explanation:
The distinction between access and learning depends on treating examination performance as relevant evidence about learning, even if it is not a perfect measure.

B.It proves that supervisor attention was the true cause because participants in workplace studies commonly modify their behavior when observed
C.It offers an alternative explanation that limits causal certainty
D.It restates the result using more precise statistical terminology

B.Selection bias; sample interns from the full roster using a probability method
C.Recall bias; replace all self-reports with supervisors' estimates of intern sleep
D.Interviewer bias; administer the same survey at the end of the seminar

B.The second scale is automatically more valid because it incorporates revisions
C.The scores cannot be analyzed unless every item, response category, administration time, interviewer, and workplace condition is identical across both years
D.The study necessarily lacks external validity because it follows the same employees
Correct Answer: The change may reflect instrumentation rather than a real change in motivation

57A study finds a statistically significant association with , but the effect size is very small and the confidence interval includes effects of negligible practical importance. Which conclusion is most defensible?
Writing a research paper
Hard
