BOOKMARKED
The growing popularity of computer-based activities was widely expected to result in a decline in television viewing, since it had been assumed that people lack sufficient free time to maintain current television-viewing levels while spending increasing amounts of free time on the computer. That assumption, however, is evidently false: in a recent mail survey concerning media use, a very large majority of respondents who report increasing time spent per week using computers report no charge in time spent watching television.

Which of the following would it be most useful to determine in order to evaluate the argument?

A. Whether a large majority of the survey respondents reported watching television regularly

B. Whether the amount of time spent watching television is declining among people who report that they rarely or never use computers

C. Whether the type of television programs a person watches tends to change as the amount of time spent per week using computers increases

D. Whether a large majority of the computer owners in the survey reported spending increasing amounts of time per week using computers

E. Whether the survey respondents' reports of time spent using computers included time spent using computers at work

Note: There are two questions available with the similar stimulus and same first line but different question. The other question (complete the argument) is discussed in: the-growing-popularity-of-computer-based-activities-was-q2-80846.html

When the argument says "free-time" it means time that is not spent on work.


Case1:

Let's say the year is 1998.

A person works at the office for 8 hours a day - 0 hours of this time is spent on the computer.
He returns home at 6 p.m, watches tv for three hours and goes to sleep at 9 pm.

Let's say the year is 2014.

A person works at the office for 8 hours a day - 6 hours of this time is spent on the computer.
He returns home at 6 p.m, watches tv for three hours and goes to sleep at 9 pm.

Time spent using computers has increased but free time to watch tv has not been affected.

Case 2:

Let's say the year is 2012.

A person works at the office for 8 hours a day - 6 hours of this time is spent on the computer.
He returns home at 6 p.m, watches tv for three hours and goes to sleep at 9 pm.

Let's say the year is 2014.

A person works at the office for 8 hours a day - 6 hours of this time is spent on the computer.
He returns home at 6 p.m, uses his free time on the computer for two hours and as a result has only one hour to watch tv before he can go to sleep at 9 pm..

Time spent using computers has increased and free time to watch tv has been affected.

How can you think so much in limited time frame.

A well deserved 740 is your score.

Can someone please explain the difference between A and E. I narrowed it down to these 2 and chose the wrong one-A. Here was my reasoning -- Evidence is false b/c comp time went up and the television time didn't go down.

A) If i used the variance test on this, I get the following:

Group 1) People watching TV regularly only watched it for a short amount of time, so adding computer time didn't affect their overall reduction of TV time. Therefore, it strengthens the conclusion.

Group 2) People watching TV regularly watched it a LOT and adding computer time SHOULD reduce the TV time. Therefore the argument is false because it contradicts it.


E) Using the variance test again, I get the following:

Group 1) People used their computers at work so it didn't affect their free time at home. Conclusion is strengthened.

Group 2) People used their computers only at home so it did affect their free time at home. Conclusion is weakened.

Can any experts chime in please?

Can someone plz explain it to me clearly? I seriously do not get it at all . :(

Isn't it about "even with increased time spent on computers the time spent on TV viewing has not changed"?
So it is the TV viewing time that is the prime concern ryt? Not the free-time theory

Question:The growing popularity of computer-based activities was widely expected to result in a
decline in television viewing, since it had been assumed that people lack sufficient free
time to maintain current television-viewing levels while spending increasing amounts of
free time on the computer. That assumption, however, is evidently false: in a recent mail
survey concerning media use, a very large majority of respondents who report increasing
time spent per week using computers report no charge in time spent watching television.
Which of the following would it be most useful to determine in order to evaluate the
argument?

A. Whether a large majority of the survey respondents reported watching television
regularly
B. Whether the amount of time spent watching television is declining among people
who report that they rarely or never use computers

C. Whether the type of television programs a person watches tends to change as the
amount of time spent per week using computers increases

D. Whether a large majority of the computer owners in the survey reported spending
increasing amounts of time per week using computers

E. Whether the survey respondents’ reports of time spent using computers included
time spent using computers at work

Let's figure out the conclusion first as it is the difficult part in this question

Conclusion: The popularity of computer based activities has not led to the decline of television viewing.

Why??

Premise: The survey results said that people are spending more time on the computer per week but no change in time spent watching television.
Earlier it was assumed that people have less sufficient free time and thus TV viewing will decline but this assumption is wrong and People have sufficient free time to not to reduce TV viewing.

For Evaluate question type, The answer to the questions above should swing the conclusion from one extreme to another

A. Whether a large majority of the survey respondents reported watching television
regularly

Ans is Yes,then a large majority of the survey respondents reported watching television regularly. It does not do anything to the conclusion
No again nothing to the conclusion

B. Whether the amount of time spent watching television is declining among people
who report that they rarely or never use computers
Well this class of people is out of scope. We are only worried about people who use computers in free time

C.Whether the type of television programs a person watches tends to change as the
amount of time spent per week using computers increases

We are only bothered about time spent watching TV and not really concerned about the content

D. Whether a large majority of the computer owners in the survey reported spending
increasing amounts of time per week using computers

the large majority of computer owners in the survey will be a subset of total no. of people responded in the survey.If this population of computer owners in the survey is 99% of the total survey size then surely TV viewing is effected but if this size of computer owners is only 1% then TV viewing may not be effected because you will have more people who may not be owners but still be using computers the results of this class will define what happens to TV viewing...
So ruled out.

So even if you answer this question you cannot arrive at the conclusion.


E.Whether the survey respondents’ reports of time spent using computers included
time spent using computers at work

If the answer is yes then surely time spent on computers is more but usage in free time may be less and hence TV viewing remains same
If the answer is no then using computers only considers free time which will be less and hence people will have less time to watch TV..

(E) Whether the survey respondents' reports of time spent using computers included time spent using

OA:E.

I can understand E is the correct answer,but I can not understand why A is not correct.
My understanding for A is:If the survey respondents are never watching TV, so the conclusion of no change in watching TV has no sense(because they never watch TV), so if in this situation answer A can weaken the argument.

Please help me to clarify my understanding of A.



Tough question

basically the argument says that IF you spot the reason why the people dedicate more time to pc AND at the same time the amount of time dedicate to TV is more or less the same of before.....you have the right answer.

E says that the amount of time dedicated to PC is not a single time but shared, between two situations. In other words, if you have 10 hours dedicated to the computer and 10 hours dedicated to TV is not possible. BUT in E the time spent to PC is not 10 hours but 10 hours combined bewtween home AND office, so this time is not 10 + 10 but 10 combined. As result, you have time to dedicate to watch TV, eventually the other 10 hours

Hope is clear


I initially thought that this question is about representativeness of the survey group (typical mistake in survey type q-s). If the survey group didn't have any regular tv watchers than it would mean that it is irrelevant for the argument.

Someone please share its thoughts. Thanks in advance!

Spent 6 mins on this question, but still committed stupid careless mistake. I kept questioning why OA excludes work from computer-based activities, until I realized that I overlooked "lack sufficient free time".
My second time missing out a keyword (the previous one was the phrase "flight delay" in OG Q22). Really hard to avoid the mistake.

i see most of us explain the solution in this case. I think it is better mention the tech. concept behind the answer. I mean how can we evaluate an argument in general, referring to the CR books and how to apply the concept in such case.
please help.

Many a people are pointing out BLATANTLY WRONG options, based on god knows what criteria.
FIRST understand the argument.
THEN understand the question.

WE have to evaluate the ARGUMENT. THE ONLY WAY TO CHOOSE A CORRECT OPTION IN EVALUATE AN ARGUMENT IS TO GET TWO POLARISING OPPOSITE ANSWERS WHEN WE ASK A COMMON QUESTION

The stimulus talks about FREE TIME -the time that a person spend time on computer and thus cannot afford to spend watching TV.
But surprisingly the person is doing both.
how can this be possible.
This can only be possible when he is taking into account the time he spends at work as the time spend on computers.

CURRENTLY IN THE SURVEY HE IS BEING ASKED ""DOES YOUR TV WATCHING TIME HAS DECREASED BECAUSE OF COMPUTER"?

OBVIOUSLY THE PERSON WILL SAY NO, BECAUSE HE IS INCLUDING HIS WORK TIME.

THE CORRECT QUESTION THAT NEEDS TO BE ASKED IS "AFTER COMING HOME, DO YOU SPEND THE SAME TIME IN WATCHING TV AS YOU USED TO DO BEFORE COMPUTERS?"

Now if the person have a computer at home and uses it a lot,then he will say:- yeah man.. i don't watch tv anymore.. i surf and google and stuff.
Now if the person do not have a computer then he will say:- no man.. i watch the same programs , same time.. nothing changed.

THIS IS THE ONLY WAY TO EVALUATE AN ARGUMENT. LEARN IT, UNDERSTAND IT AND USE IT. IT IS CALLED VARIANCE TEST.

SO the correct answer is E

Note: There are two questions available with the similar stimulus and same first line but different question. The other question (complete the argument) is discussed in: the-growing-popularity-of-computer-based-activities-was-q2-80846.html

That assumption, however, is evidently false: in a recent mail survey concerning media use, a very large majority of respondents who report increasing time spent per week using computers report no charge in time spent watching television.

As per : The growing popularity of computer-based activities was widely expected to result in a decline in television viewing
Earlier
total free time =10 hrs week
Computer time = 5 hrs
TV time = 5 hrs

Now
total free time =10 hrs week
Computer time = 9 hrs
TV time = 1 hr

But as per the argument '

in a recent mail survey concerning media use, a very large majority of respondents who report increasing time spent per week using computers report no charge in time spent watching television.

total free time =10 hrs week
Computer time = 5 hrs
TV time = 5 hrs

Now
total free time =14 hrs week
Computer time = 9 hrs
TV time = 5 hr


Which of the following would it be most useful to determine in order to evaluate the argument?

A. Whether a large majority of the survey respondents reported watching television regularly

Assume this: Majority of people
total free time =10 hrs week
Computer time = 5 hrs
TV time = 0 hrs

Now
total free time =14 hrs week
Computer time = 9 hrs
TV time = 0 hr


Then definitely it changes our conclusion.


B. Whether the amount of time spent watching television is declining among people who report that they rarely or never use computers

C. Whether the type of television programs a person watches tends to change as the amount of time spent per week using computers increases

D. Whether a large majority of the computer owners in the survey reported spending increasing amounts of time per week using computers

E. Whether the survey respondents' reports of time spent using computers included time spent using computers at work
