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.

Re: The growing popularity of computer-based activities was - Q1 [#permalink] New post 27 Apr 2014, 10:24
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..
