Set consisting of five different elements

by goelmohit2002 Thu Oct 08, 2009 4:18 am

Hi All,

When one a GMAT question (in statistics) says that set consist of five different positive elements, then do we have to consider both the following possibilities ? If only one of them, then can some one please tell why ?

a) (1,2,3,4,5)
b) (1,1,2,2,2,2,2,3,3,4,4,4,4,4,5,5,5,5)

Please note that as such option B too has only five different positive elements.

Thanks
Mohit

Goelmohit:
I think I would need an example to specifically answer your question. Typically the GMAT is extremely clear when it words a question so that you know for sure which case it's talking about.

If a question stated, "the average of five distinct positive integers is 3" then (1) would be the correct list and (2) would be incorrect.

If a question stated, "In a survey given to a class of 18 students, there are five possible responses," then (2) would be a possible data set.
