Govt Survey [#permalink] New post 03 Apr 2005, 21:06
Areport of a government survey concluded that Center City was among the ten cities in the nation with the highest dropout rate from its schools. The survey data were obtained by asking all city residents over the age of 19 whether they were high school graduates and computing the proportion who were not. Acity school official objected that the result did not seem accurate according to the schools’ figures.

The school official can most properly criticize the reasoning by which the survey report reached its result for failure to do which one of the following?

(A) take into account instances of respondents’ dropping out that occurred before the respondents reached high school
(B) ask residents whether they had completed their high school work in fewer than the usual number of years
(C) distinguish between residents who had attended the city’s schools and those who had
received their schooling elsewhere
(D) predict the effect of the information contained in the report on future high school dropout rates for the city
(E) consider whether a diploma from the city’s high schools signaled the same level of achievement over time

1) A report of a government survey concluded that Center City was among the ten cities in the nation with the highest dropout rate from its schools.

2) The survey data were obtained by asking all city residents over the age of 19 whether they were high school graduates and computing the proportion who were not.

3) A city school official objected that the result did not seem accurate according to the schools’ figures.

The school official can most properly criticize the reasoning by which the survey report reached its result for failure to do which one of the following?

(A) take into account instances of respondents’ dropping out that occurred before the respondents reached high school
- If this is true, then it's indeeed the school dropout rate is miscalculated, as a particular age group (below 19) has been excluded from the survey.

(B) ask residents whether they had completed their high school work in fewer than the usual number of years
- This is not considered dropping out of school.

(C) distinguish between residents who had attended the city’s schools and those who had received their schooling elsewhere
- Not important either. We're concerned with student of center city dropping out, it does not matter where they came from.

(D) predict the effect of the information contained in the report on future high school dropout rates for the city
- Out of scope.

(E) consider whether a diploma from the city’s high schools signaled the same level of achievement over time
- Not important too. This would not affect the figures for the dropout rate.

I'll take A

C.

(A) take into account instances of respondents’ dropping out that occurred before the respondents reached high school
###We are interested in drop out rate in its schools, not specifically in its high schools. Therefore, no matter when they dropped out they are all school drop-outs.

(C) distinguish between residents who had attended the city’s schools and those who had
received their schooling elsewhere
###Its not necessary that everyone now living in the city had studied in one of its schools.

C. You cannot take the # of people drop out of High School somewhere else to calculate this city's figure.

Dropout rate is calculated on all grades of school cumulatively and not just on high school dropouts. So, A/B/D/E goes out of the window in first shot.

Even if we consider high schools to be the only schools in the city, B/C become contenders for the below reasons.
B) --> If I complete my high school early(before age of 19), then I am not a high school graduate(better than average graduate) and will be counted in dropouts by survey standards even if I am not. This should increase the dropout rate and skew the dropout figures upward.
C) --> If residents take schooling in city and leave to other cities for jobs, it will skew the dropout figures upward. Same holds true for uneducated people getting attracted to the city as this will increase proportion of dropouts.
D/E)--> Clearly Out of Scope as they dont talk about composition of dropouts ratio calculation or their effects on dropout ratio.
A) --> Seems to me like an assumption

Need to know how to pick between B and C if high schools are considered to be the only schools in the city. F1
