Traditionally, students at Kelly University have evaluated professors on the last day of class. But some professors at Kelly either do not distribute the paper evaluation forms or do so selectively, and many students cannot attend the last of day of class. Soon, students will be able to use school computers to evaluate their professors at any time during the semester. Therefore evaluations under the new system will accurately reflect the distribution of student opinion about teaching performance.

Which one of the following is an assumption required by the argument?

(A) Professors who distribute the paper evaluation forms selectively distribute them only to students they personally like
(B) Student can wisely and insightfully asses a professor’s performance before the end of the semester
(C) The traditional system for evaluating teaching performance should not be used at any university
(D) Nearly all professors who fail to distribute the paper evaluation forms do so because they believe the students will evaluate them unfavorably
(E) Dissatisfied students are in general not more likely than satisfied student to submit a computerized evaluation

IMO E.

The conclusion states that the computerised system will be able to capture "accurate distribution of student opinion" now that the professors cannot choose their students or do away with the process completely.

A. It is tempting but gives no information whether the students they like also represent accurate distribution of student opinion or not. For example, in a class of 100, 90% rate the teacher favourably and 10% unfavourably and of the 10 students selected by the teacher, 9 rate her favourably and 1 rates her unfavourably then the students selected give the accurate distribution, otherwise not. No such information provided. Incorrect.

B. The conclusion is about the "distribution of student opinion" and not about "the accuracy of student opinion". Even if they accurately evaluate or not has got nothing to do with our conclusion. Incorrect.

C. Irrelevant. Incorrect.

D. Tempting. But again no information provided about how such students actually end up rating the professors in the term of "distribution of opinion". This just states a reason why professors do not distribute. Not what actually happens. Does not hit the conclusion. Incorrect.

E. If those who are rate the professors negatively are more likely to submit the feedback, then the distribution of opinion will be skewed and not accurate. Negation breaks down the conclusion. Correct.

I feel like the choice should be E;

Incase unhappy students are significantly more likely to cast their vote, the new system would lead to a wrong distribution of the opinion of the overall student body as the results would be scewed towards the negative side.

I found the answer choices A and D very tempting too, but they are both dealing with how the rating process used to be and are thus somewhat out of scope.

B & C are quite judgemental and I thus outlined them quite quickly.
C is very irrelevant, whereas B might lure you into thinking the students ability to judge the professors in insightfully has relevance to the question.

To quote Admiral Akbar concerning point B:

"Its a trap" :)

Regards,
Chris

Premise - Students evaluate professor on last day of the semester. This evaluation is not okay as some professors do not submit evaluation paper or they give it to selected students. In addition many students do not attend last day of the class. Now, Computer based evaluation is available throughout the semester.
Conclusion - With this new change evaluation will be accurate.
Assumptions - 1. All the professors evaluation forms will be available.
2. Students evaluating professors performance during the semester is good enough as that of evaluation done on the last day.
3. Students won't be selective in computer based evaluation.

Which one of the following is an assumption required by the argument?

(A) Professors who distribute the paper evaluation forms selectively distribute them only to students they personally like - Same as Premise. It's not an assumption.
(B) Student can wisely and insightfully asses a professor’s performance before the end of the semester - Correct. Students don't need to wait for the last day. They can evaluate on any day during the semester. Negate: Students cannot wisely and insightfully asses a professor's performance before the end of the semester. This means evaluation won't be good enough as many students cannot attend the last day of the class.
(C) The traditional system for evaluating teaching performance should not be used at any university - Irrelevant. we are not concerned with any other university.
(D) Nearly all professors who fail to distribute the paper evaluation forms do so because they believe the students will evaluate them unfavorably - But it is not supporting the cause why computer based evaluation will be accurate.
(E) Dissatisfied students are in general not more likely than satisfied student to submit a computerized evaluation - Negate: Dissatisfied students are in general more likely than satisfied students to submit a computerized evaluation which means results may or may not be accurate.

Does not affect our conclusion. Drop it.

(B) Student can wisely and insight-fully asses a professor’s performance before the end of the semester
while the students can fill up the forms anytime, the author hopes that they are able to assess the performance correctly by the end of semester. Negating this will destroy the conclusion that they will [b]accurately be able to assess. Keep it.[/b]

(C) The traditional system for evaluating teaching performance should not be used at any university
Irrelevant. Drop it.

(D) Nearly all professors who fail to distribute the paper evaluation forms do so because they believe the students will evaluate them unfavorably
Irrelevant Drop it.

(E) Dissatisfied students are in general not more likely than satisfied student to submit a computerized evaluation
Negating this will give that the Dissatisfied students are in general as or less likely than satisfied student to submit a computerized evaluation. but this will not affect the accurate [b]distribution of student opinion. Dissatisfied will still be. only the satisfied will be less. None the less. the distribution will be tiletled towards dissatisfaction but accurate. Drop it.[/b]

Answer: B

This is a difficult Assumption question that requires you to pay particular attention to the wording of the conclusion. The argument here is that the computerized evaluations will “accurately reflect the distribution of student opinion.” For this statement to be true, it is necessary that the students who do fill out the evaluations are representative of all other students (so that an accurate reflection of all students gets presented). That is, if none of the very disappointed or very pleased students respond, then the evaluations will not accurately reflect everyone. So all types of students need to respond, and they need to respond honestly.

Answer choice (A): The conclusion is about the computerized evaluations, not the paper evaluations, so this answer choice cannot be correct.

Answer choice (B): This is a tempting wrong answer choice, but keep in mind that the conclusion is not about whether the evaluations will be correct in their assessment, but merely that they will accurately reflect how all of the students truly feel.

Answer choice (C): Whether or not the paper evaluation system should ever be used is not necessary to the argument about the representativeness of the new computerized system.

Answer choice (D): The motivation of professors who do not distribute the paper evaluations is unrelated to the argument about computerized evaluation representativeness.

Answer choice (E): This is the correct answer choice. As mentioned above, this shows that there is no a tendency for a certain type of student to submit evaluations more frequently than other students. Negated, this answer choice would strongly attack the conclusion by showing that dissatisfied students will submit evaluations more often, and thus the overall reflection of student opinion will seem more negative than it actually is (and therefore not accurately reflect student opinion).

Kudos will be given to the BEST solution posted BEFORE the OA is revealed!


Conclusion
evaluations under the new system will accurately reflect the distribution of student opinion about teaching performance

There should not be any skew in the distribution of student opinion.
E tells us that Dissatisfied students are at most as likely as the satisfied students to submit evaluation.

E for me as well.
