A study attempting to link fertility with increased sexual availability concluded that women unconsciously dress more attractively during ovulation. The study was conducted using pairs of photographs of 200 women and volunteer viewers who chose the photograph in which they thought the woman appeared more attractive. Researchers found that 67% of the time viewers chose the photo taken when the woman was ovulating.

The methodology of the study above is flawed for which of the following reasons?

(A) The study fails to specify what is meant by the word attractive, leaving it up to the opinion of the individual viewer.
-->this attacks the method .. if attractive is not defined we can think of this situation in extremes...say 67% of the people thought a "sexy" look was attractive..this would strengthen the argument..but let's look at the other extreme and say 67% thought a woman with no makeup and looked rather "plain jane" was attractive..this would seriously weaken the argument
(B) Because all the viewers were male, the results of the study were skewed by individual responses to attractive women.
-->this is not a flaw but slightly strengthens the argument
(C) The study fails to account for the psychological complexity of sexual desire in women
-->the study is only concerned with fertility and increased sexual availability NOT psychological factors
(D) The study assumes that women will dress more attractively when they have greater sexual desire.
-->this is not a flaw in the methodology
(E) Most women do not know when they are ovulating, and so would not dress more attractively on that day.
-->this is not a flaw in the methodology of the experiment


I burned 2:07 on this question and only got it using POE. I think we have to really pay attention to the wording of the question stem. The METHODOLOGY of the study is flawed because?...We should attack the method in which the study was carried out.

I have eliminated C,D, & E straightaway but got stucked between A and B. Finally selected A but taken 3 minutes. In this type of flaw questions we can increase our speed if we can decide the degree to which conclusion of the author is supported by the premises. That is- If the stimulus contains an argument, determine whether the argument is strong or weak (Primary objective-3 of CR bible). Hope to hear your views!!!
Thanks.

I think oa is wrong. Attractiveness doesn't need definition. Answer cannot be so out of whack :-)

I chose A as well. If the parameters aren't properly defined it is hard to take the findings as true.

That's because of two reasons:
a) We are not discussing the sexual desires of women (we're talking about how they dress when they ovulate)
b) The statement makes it seem like women are dressing more attractively consciously. But the stimulus tells us that this is not the case. They are doing it unconsciously!

I too was deciding between A and D. I ruled out D because of the two reasons above and got the answer in 1 minute 41 seconds.

I don't understand why A is the answer. The whole point of the experiment was to leave it up to their interpretation, right? I chose B.

It looks more like a LSAT question than a GMAT one.

A study attempting to link fertility with increased sexual [#permalink] New post 24 Feb 2013, 05:42
what should be the answer to the question and how to approach this ?

A study attempting to link fertility with increased sexual availability concluded that women unconsciously dress more attractively during ovulation. The study was conducted using pairs of photographs of 200 women and volunteer viewers who chose the photograph in which they thought the woman appeared more attractive. Researchers found that 67% of the time viewers chose the photo taken when the woman was ovulating.

The methodology of the study above is flawed for which of the following reasons?

1) The study fails to specify what is meant by the word attractive, leaving it up to the opinion of the individual viewer.

2)Because all the viewers were male, the results of the study were skewed by individual responses to attractive women.

3)The study fails to account for the psychological complexity of sexual desire in women

4) The study assumes that women will dress more attractively when they have greater sexual desire.

5)Most women do not know when they are ovulating, and so would not dress more attractively on that day.

So, basically the strategy to tackle flaw question is this: the stimulus must be an argument. As such, it has premise(s) and conclusion. Then It must have an assumption, so is this assumption that you have to attack, weakening.

An assumption make the argument stronger. In flaw question you make the assumption more weaken. it is something quite similar to the reverse of finding the assumption question.

Be careful: it is different from weaken question because: this attack the assumption, instead in weaken question you basically attack the conclusion though not in isolated manner but relating the latter with the premise(s) of the stimulus.

For these reasons, for these layers of reasoning in a single question Cr is difficult and needs more practice than Sc for instance.

So, back to the question:

Conclusion: A study attempting to link fertility with increased sexual availability concluded that women unconsciously dress more attractively during ovulation.

Stimulus: The study was conducted using pairs of photographs of 200 women and volunteer viewers who chose the photograph in which they thought the woman appeared more attractive. Researchers found that 67% of the time viewers chose the photo taken when the woman was ovulating.

1) The study fails to specify what is meant by the word attractive, leaving it up to the opinion of the individual viewer.

Nope. it says that the viewers thought what is the word attractive, at least for them. opinion and thoughts could be different

2)Because all the viewers were male, the results of the study were skewed by individual responses to attractive women.

This basically sayas that the study was biased. Maybe or not........we are not sure

3)The study fails to account for the psychological complexity of sexual desire in women

This seems good. Because the conclusion says that the women are unconsciously but here we read that they are and the women's desire is complex and also we know that during ovulation, women have MORE desire

4) The study assumes that women will dress more attractively when they have greater sexual desire.

This is our assumption but we want the assumption but something more: we want weaken the assumption, we do not want the asumption itself

5)Most women do not know when they are ovulating, and so would not dress more attractively on that day.

We already know it from the stem

For me C is the answer.

Got a PM to respond to this and I oblige :)

Understanding the Passage

Conclusion: women unconsciously dress more attractively during ovulation

Premises:

Basically, two photos of each of the 200 women were taken: one in which the women was ovulating and one in which she was not.

These photos were shown to the volunteers to select one photo from each of the pair of photos - selected photo is more attractive.

It was found that 67% of the time volunteers chose those photos in which the woman was ovulating.

Based on this, the researchers thought this increased attractiveness must be the result of dressing sense. So, they thought women unconsciously dress attractively during ovulation.

Prethinking

As we saw above that the authors made the assumption that the increased attractiveness during ovulation period is the result of better dressing sense.

I think if we spend some more time prethinking, we can probably find some more assumptions but ler's directly move to the option statements.

Analysis of option statements

Question Stem: The methodology of the study above is flawed for which of the following reasons?

(A) The study fails to specify what is meant by the word attractive, leaving it up to the opinion of the individual viewer. - This seems interesting. If different individual viewers had different perceptions of attractiveness, then they would have rated the photos using their own different parameters of attractiveness. Given that attractiveness is such a vague word, different people would probably have very different conceptions of attractiveness. If this so, the data that 67% of people preferred photos of woman taken during their ovulation period, becomes doubtful. But I am not really sure of this answer choice because the conclusion also uses this term "attractiveness", so probably the researchers are not really concerned about the different perceptions of attractiveness. Let's keep this option aside. This may or may not be the answer.

(B) Because all the viewers were male, the results of the study were skewed by individual responses to attractive women. - As we understood in the passage analysis, the viewers were shown two photos of each women and they had to pick one photo of each women. They didn't have to select one woman over other. Therefore, this option is incorrect.

(C) The study fails to account for the psychological complexity of sexual desire in women - This is going way off the mark. Even if this option makes some sense, it only impacts the conclusion. The question stem specifically asks for a question stem that finds the flaw with the methodology. Therefore, this option is incorrect.

(D) The study assumes that women will dress more attractively when they have greater sexual desire. - When do women have greater sexual desire? during ovulation? I don't know and neither can GMAT expect candidates to know this. Given the use of these terms, this goes off the track. Therefore, this option is incorrect.

(E) Most women do not know when they are ovulating, and so would not dress more attractively on that day. - This is interesting and I see that a lot of students on the forum have marked this as the answer. This looks tempting at the face of it. But it is incorrect. Two reasons: First, the conclusion specifically says that women unconsciously dress more attractively. Therefore, the conclusion cannot be impacted by this statement - the conclusion basically doesn't assume that women know when they are ovulating. Second reason is that we have to find a flaw in the methodology, not the conclusion.

So, after this analysis, we find that only one contender is left i.e. Option A. So, that is the correct answer.
Hope this helps :)

Thanks,
Chiranjeev

Hi TheNona,

The logic for A is:
Premise: O (ovulating) = A (Attractive)
Conclusion: O = A* (dress attractively)
Wrong logic: A* maybe different from A, or A* is only a subcategory of A.

Now, I will apply the logic above for the question:

Premise 1: volunteers will choose photos of ATTRACTIVE women.
Premise 2: 67% of volunteers picked photos of women who are ovulating.
Conclusion: Ovulating makes women DRESS ATTRACTIVELY.

You see the flaw, "ATTRACTIVE" does not mean "DRESS ATTRACTIVELY". For example, Volunteers chose photos of attractive women because women's skin is more beautiful when they are ovulating.

I saw many people chose E, indeed after used POE, I narrowed down to A & E.
But E is not correct because E says: don't know ovulating --> wouldn't dress attractively. The logic SEEMS to indicate that if women know they're ovulating, they would dress attractively. --> "Ovulating" leads to "dress attractively".
So E maybe supports the author's conclusion, not undermines it. Between A & E, clearly E is not a solid answer. --> I eliminate E.

(B) Because all the viewers were male, the results of the study were skewed by individual responses to attractive women.Not strong enough
(C) The study fails to account for the psychological complexity of sexual desire in women.Not relevant
(D) The study assumes that women will dress more attractively when they have greater sexual desire.Not relevant
(E) Most women do not know when they are ovulating, and so would not dress more attractively on that day.Has a point but A sounds perfect

Eh, not a huge fan of this question; the point of attraction is that is in the eye of the beholder, if people in a society are asked to rate the attractiveness of others, there will end up being a somewhat general consensus if you have a broad enough sample.
