### HideShow timer Statistics

The proportion of women among students enrolled in higher education programs has increased over the
past decades. This is partly shown by the fact that in 1959, only 11 percent of the women between twenty and
twenty-one were enrolled in college, while in 1981, 30 percent of the women between twenty and twenty-one
were enrolled in college.
To evaluate the argument above, it would be most useful to compare 1959 and 1981 with regard to which of
the following characteristics?
(A) The percentage of women between twenty and twenty-one who were not enrolled in college
(B) The percentage of women between twenty and twenty-five who graduated from college
(C) The percentage of women who, after attending college, entered highly paid professions
(D) The percentage of men between twenty and twenty-one who were enrolled in college
(E) The percentage of men who graduated from high school

P1 - Prop of Women enrolled has gone up in past decaded
P2 - 1959 - 11% (20-21) while 1981 - 30% (20-21)
To evaluate the argument above, it would be most useful to compare 1959 and 1981 with regard to which of
the following characteristics?
(A) The percentage of women between twenty and twenty-one who were not enrolled in college - Out of Scope
(B) The percentage of women between twenty and twenty-five who graduated from college - Out of Scope
(C) The percentage of women who, after attending college, entered highly paid professions - Irrelevant
(D) The percentage of men between twenty and twenty-one who were enrolled in college - Irrelevant (Women are the only ones considered in this argument)
(E) The percentage of men who graduated from high school - the first line says proportion of women AMONG students (Men and Women) - BEST ANSWER

(D) The percentage of men between twenty and twenty-one who were enrolled in college
(E) The percentage of men who graduated from high school

My take is A.

The very first sentence is not a premise but a conclusion of the stimulus. The percentage of women | among students enrolled in higher education programs | has increased over the past decades. So the percentage of women has increased, is the conclusion. This conclusion is followed by a supporting premise that those between ages twenty and twenty-one (NICE!!!! ) were, in '59 - 11% and in '81 - 30%. Now to substantiate the claim and properly support the given premise, we need to know what the population of women of that given particular age group was at both the times. This can be understood only from option A. Just because a percentage was given in the stimulus doesn't mean the claim stands strong. We need to know the wholesome to be able to compare accurately. Or some means to get to the perfect wholesome. Option A alone gives the relevant information.

Answer : Option D

Men in College + Women in College : 100 %

For the % enrolment of women to go up , % enrolment of men has to reduce.

Classic example of the "scope shift".

Conclusion argues that proportion of women among the students enrolled has increased. It means that there were more women on campus (women/all students)

Evidence used is that of proportion of women enrolled among 20-21 year old females. It's very different proportion: (women enrolled)/(all women between 20-21).

To reconcile the evidence with the desired conclusion we should also examine the same proportion for men - (D)

(A) The percentage of women between twenty and twenty-one who were not enrolled in collegeComparison is b/w the women among the students enrolled and the men among the students enrolled.Those who do did not enroll are irrelevant to the argument.
(B) The percentage of women between twenty and twenty-five who graduated from collegeAge group changed.hence not comapring parallel things
(C) The percentage of women who, after attending college, entered highly paid professionsirrelevant
(D) The percentage of men between twenty and twenty-one who were enrolled in collegeThis can clearly evaluate whether the proportion has increased or is it an assumption.
(E) The percentage of men who graduated from high school.% of men who graduated is nt the issue.The matter of question is the students who enrolled.

To compare the proportion of women among students enrolled in higher education programs it would be best to compare 1959 to 1981 wiht regard to the number of men among the students.

Shouldn't it be A? It states the proportion of women increased. And then it only gives the increase of women in age group of 20 to 21. What about women beyond 21 or below 20? The proportion probably decreased in that group. Hence, the overall proportion probably could be the same?

Can someone explain.

Thanks

I am not sure if my explanation would be any better than the ones given above...

An implicit assumption that I am making here is that the age group being referred to is 20-21

1) The argument states that the proportion of women among students enrolled in college has increased. This means that the ratio W/(W+M) has increased.
2) 1959: Of the women between 20-21, only 11% were enrolled in college. Assuming the number of women between 20-21 to be 100, then W here comes out to be 11
3) 1981: Of the women between 20-21, only 30% were enrolled in college. W here comes out to be 30

30/(30+M) > 11/(11+M) -> To evaluate this, all we need to know is M. Hence D.

Your right, looking at one age group does not justify whether the total proportion has increased or decreased. Note that if we really wanted to evaluate whether the total proportion of women had increased or decreased, then we would have to compare the total number or women and male students across all ages.

However we can only choose from the answers provided. And the only one that has any bearing is D. None of the other answers help you compare the proportion of women to men.

Hope that kinda helps ...

The proportion of women among students enrolled in higher education programs has increased over the
past decades. This is partly shown by the fact that in 1959, only 11 percent of the women between twenty and
twenty-one were enrolled in college, while in 1981, 30 percent of the women between twenty and twenty-one
were enrolled in college.

To evaluate the argument above, it would be most useful to compare 1959 and 1981 with regard to which of
the following characteristics?

(A) The percentage of women between twenty and twenty-one who were not enrolled in college
(B) The percentage of women between twenty and twenty-five who graduated from college
(C) The percentage of women who, after attending college, entered highly paid professions
(D) The percentage of men between twenty and twenty-one who were enrolled in college
(E) The percentage of men who graduated from high school

ok....

I initially thought about A.
Now I realize why answer should be D.

The conclusion is

The proportion of women among the total students who enrolled in colleges has increased.
'Among the total students who enrolled in colleges' includes ONLY the enrolled students.

The total number doesn't include the one who didn't enroll in a college.

Thus, in order to see whether the proportion has increased, you only need to consider the ones who enrolled.

This rules out A.

Why is it not E? The question refers to "proportion of women among students enrolled" and not "proportion of women between 20 and 21 among students enrolled". D offers a more specific answer to a general question. Can someone please explain?

The key to this argument is: The proportion of women among students enrolled in higher education programs.

That is, we are comparing the proportion of women to men at colleges. The evidence used, however, is the percent of 20 -21 yrs. old females attending college over two time periods, 1959 and 1981. Even if more 20-21 yrs. old females are attending college in proportion to the overall population of females, that fact alone does not speak to the proportion of women to men in college. To illustrate: let's say in 1959, 20% of those attending college were women. In 1981 that number could fall to only 10%. This is not inconsistent with the increase in attendance amongst 20-21 yrs. old females. While their ranks may have swelled, perhaps there has been a drop off in the percentage of 18-19 or 25 and over.

Thus to evaluate the argument, we need to know how many men were enrolled in college. Therefore the answer is (D).

Hope that helps clear any confusion .

D in 1.28

when two percentages are given we need to know the total sample set in order to compare them.
