This improvement is certainly a direct result of her weekly quizzes.
Which of the following, if true, casts the most serious doubt on the conclusion drawn above?
Argument Analysis
Pre-Thinking
Conclusion Clarification
N/ A
Pre-Thinking Approach
Let’s see how we can make the conclusion less believable. To do so, we will look at the logical structure, focusing on linkage 1 and the conclusion.
Note that linkage 1 links two facts in a causal relationship, leading to the conclusion. Thus the way to weaken the conclusion will be to break/weaken this linkage or causal relationship i.e. find an alternate explanation that may have led to the effect (improvement in the students’ performance so far this year).
Linkage#1 – Students’ performance has improved by 5% as compared to the performance of the senior batches.
- Weakener - What if there is some other factor that accounts for the improvement in the students’ performance?
-
- Instance 1: For example, there could have been a change in the teaching methodology that might have led to the improved performance. For example, what if this year the college introduced educational videos or extra classes for the new batch?
With this understanding in mind, let’s take a look at the option statements.
Answer Choices
A
Many students who would not have allotted much time to study Statistics are now spending extra time on the subject because of the weekly quizzes.
Incorrect - Opposite
The extra time spent in studying statistics because of the weekly quizzes could be taken to support the conclusion.
B
Some of the students in the new batch perform better in Statistics than they do in other subjects.
Incorrect - Irrelevant
This option presents a superfluous comparison between performance of some students in statistics and their performance in other subjects.
C
The Statistics textbook prescribed for the introductory course this year is considerably easier to understand than the textbook used previously.
Correct
This option is written along the lines of pre-thinking. It introduces another factor that can have a direct impact on students’ performance.
D
In a recent evaluation by the school board, the Statistics professor was ranked the best professor in the school.
Incorrect - Irrelevant
The ranking of the professor doesn’t tell us whether there was a connection or lack of the same between the weekly quizzes by the professor and the performance of the new batch this year.
E
Most students feel that the weekly quizzes are making it difficult for them to concentrate on other subjects.
Incorrect - Irrelevant
The difficulty in concentrating on other subjects is irrelevant to the argument, which deals only with the better performance in the subject of Statistics this year.
