Women make up a larger proportion of workers in the information services industry than they did ten years ago. This is partly shown by the fact that in 1985, only 7 percent of women in the workforce were employed in the information services industry, but in 1995, over 16 percent of women in the workforce were employed in the information services industry.

In evaluating the argument above, it would be most useful to compare 1985 and 1995 with regard to which of the following characteristics?


(A) The percentage of women in the workforce who were not employed in the information services industry

(B) The percentage of women who are now retired who have worked in the information services industry

(C) The percentage of women who have been promoted to managerial positions within the information services industry

(D) The percentage of men in the workforce who were employed in the information services industry

(E) The percentage of men who will soon be eligible for employment in the information services industry

We dont really have to get confused here. The argument TELLS us that:
(a) of all the women there were in workforce in 1985, 7% were in IS (say 21 out of 300).
(b) of all the women there were in workforce in 1995, (atleast)17% were in IS (say 170 out of 1000, or 17 out of 100. Note the argument never said the absolute number of women in workforce increased).

The argument asks us whether this change in headcount actually reflects a change in contribution in IS industry. To answer this we must know whether the number of men in IS increased, decreased, or remained constant.

D is clear winner.

Women: (IS - Information Services)
In 1985 -- 7 % women in IS 93% in other sectors.
In 1995 -- >16% woman in IS <84% in other sectors

Assume Men Proporation can have two possibilities
(Case 1)
In 1985 -- 10 % men in IS 90% in other sectors.
In 1995 -- >35% men in IS <65% in other sectors
(OR)
(Case 2)
In 1985 -- 10 % men in IS 90% in other sectors.
In 1995 -- >15% men in IS <85% in other sectors

Conclucsion :
Women make up a larger proportion of workers in the information services industry than they did ten years ago.

Case 1 Attacks the conclusion: because men make up a larger proporation workers than women.
Case 2 Supports the conclusion: because men smaller proporation workers than women.

So Option D most usefull to evaluate the above arugment.

but I still have a question regarding your explanation. I don't think that the argument is making any comparison between men and women. the argument is only focusing on women by comparing the proportion of women in 1995 to the proportion of women in 1985. Whether men have increased or decreased, I think that's not relevant. Maybe i'm wrong?? but I honestly don't see the point of looking at men because the number of men can still go either up or down, know what I mean? i'm really sorry for troubling you, but could you elaborate more?
thanks

Tarek,

This is why i chose D.

The first line of the argument says

"Women make up a larger proportion of workers in the information services industry than they did ten years ago."

One proportion on a whole cannot increase unless the other proportion of the whole is either decreasing or increasing at a slower rate than the first one.

So to find if the proportion of women has increased we need to know about the proportion increase in men.

But then the argument says that the percentage of ALL women in the workforce. So let's say that, for example, 7 percent of the women in the labor force were employed in the service industry in 1985. Then in 1995, 17 percent of the women in the labor force were employed in the service industry. Notice, the argument never said that 17 percent of the labor force IN THE SERVICE INDUSTRY are women. Rather, it said that 17 percent of ALL the WOMEN in ALL the LABOR FORCE are women. Wouldn't it make sense to see whether the total population of all the women in ALL the labor force increased or decreased? because that can truly determine whether the number of women in the service industry truly increased.

Tarek, while I choose D first, I agree with you that the answer D does need an extra assumption.

The "proportion" here relates to the mix of men and women:

Women make up a larger proportion of workers in the IT sector (than men do).

Assumption: the number of female workers and male workers did not decrease (at least stayed the same) from 1985 to 1995

1985: 7% of women workers were in IT (say 7 of all 100 female workers)
1995: 16% of women workers were in IT (say 16 of all 100 female workers)

1985: 10% of men workers were in IT (say 10 of all 100 male workers)
1995: 34% of men workers were in IT (say 34 of all 100 male workers)

1985: 7female, 10male - 35% of workers in IT were women
1995: 16female, 34male - 32% of workers in IT were women.


You need the % of men in the industry to get the above red portion

Now for ALL of this to make sense, the assumption needs to be made that the general number of female and male workers was on an upward trend.

Please explain your answer.
Thanks!

It is a straightforward application of mathematics / Data sufficiency. If someone were to tell you
Q)Is it possible to calculate the percentage of women in the Information service sector?
1)7 % of women in all the sectors work in the information service in 1985
2) 16% of women in all the sectors work in the information service 1995
If u were to combine the two premises,

To calculate the percentage of women in the Information services sector, you have to use the formula,
portion of women in information services= no. of women in information services/(no. of women in information services + no. of men in information services)

Great work on this question, everyone. I'll agree wholeheartedly that D is the correct answer, and add this:

When statistics are used in CR questions, the statistic given almost always fails to meet the conclusion directly, so focus your attention on the conclusion:

Women make up a higher proportion OF THE INDUSTRY

And see how that conclusion differs from the statistic given:

16% OF WOMEN employees are in that industry

Here, there is a clear distinction. We're looking for the ratio Women-in-the-Industry/Industry, but they give us Women-In-Industry/Total Women. The denominators are off, and we need something that better fits the correct denominator "out of the entire industry".


Train yourself to sniff out those subtle distinctions in wording when you're given statistics on CR problems, because almost always the stats that they provide are just a few degrees off of the statistic needed to draw that conclusion.

(E) The percentage of men who will soon be eligible for employment in the information services industry


D is the clear winner given the choices. BUT it is not possible to establish the conclusion based only on the percentage of men in the workforce who were employed in IS.
Again, it's clearly understood that we don't need to prove the conclusion. Our task is to choose the BEST answer that MAY be useful in making the conclusion more believable.

Thanks.

The author concludes that women make up a larger proportion of the workers in the information services industry based on his premise that a larger percentage of all women in the workforce are employed in this industry.

(A) No. Since we know that 7 percent of women in the workplace were in the information services industry, we already know that 93 percent were not in it, so this answer choice doesn’t give us any new information.

(B) No. Retired women are out of scope.

(C) No. The specific positions of women in the industry are out of scope.

(D) Yes. If we know the percentage of male workers, we can tell whether the entire workforce has grown, or whether the corresponding percentage of men in the information services industry has shrunk.

(E) No. This is out of scope. We need to know what’s happening now, not what will soon be happening.

Hi MartyTargetTestPrep,

Could you, please, help clarify my doubt regarding the wording of the below part of the argument?

Quote:
Women make up a larger proportion of workers in the information services industry than they did ten years ago.


Due to the red part, the sentence seems to be comparing the percentage of women now with the percentage of women ten years ago. For example, now women constitute 20% of workers in the information services industry, but before they constituted 15 %. Is my understanding correct?

To my mind, this sentence doesn't seem to be comparing women with men, does it?

Thank you beforehand!

Your analysis is correct. That sentence expresses a comparison between the proportion of workers currently represented by women and the proportion of workers represented by women ten years ago.

We can of course tell from what the sentence says that the proportion represented by men changed as well. All the same, the sentence itself does not express a comparison of women with men. It compares only the proportions represented by women.

Hats off to you for such a quick and clear reply MartyTargetTestPrep,

Hence, isn't the below part of the OE incorrect?

Well, not exactly. While the expression "larger proportion" is an incomplete comparison, and so the sentence does not clearly express what the proportion is larger than, I think that one can reasonably conclude that the OE is meant to convey that women make up a proportion larger than the proportion that women made up in the past.

All the same, clearly the comparison that you highlighted is incomplete, and so, yes, it could be perceived as comparing the proportion represented by women with the proportion represented by men.
