How do you understand "representative" and "not representative" sample ?

anonymous · Answer

i think it is Be but i need a second opinion

*B.

solomonzelman · Answer

Yes, I would also think so. Correct. In fact, not only random selection of seats, but it is a random game (that is how it sounds from the question).

amistre64 · Answer

if its a simple random sample, then it is representative ....  but the class i was in, noone was able to adequately define what a simple random sample meant.

amistre64 · Answer

the sample is either representative of that particular football stadium fans- hence excluding all none football fans that stay home.  Or its a good sample since only real fans go to the losing games ....

Which best describes bias, if any, from the sample surveyed? 

survey: favorite vacation locations 
sample: randomly selected visitors to a national park
 
 A.
Since the sample is randomly selected, there is unlikely to be any bias.
 
 B.
Since the people surveyed are visiting a national park, they may be biased against vacations close to home.
 
 C.
Since the people surveyed are visiting a national park, they may be biased towards national parks.
 
 D.
Since a large number of people visit national parks, the sample should be large enough to eliminate any bias.

amistre64 · Answer
