Which sample population will give the most accurate data?


a random sample of all voters in the district
a random sample of all voters in the district

a random sample of supporters of one of the candidates
a random sample of supporters of one of the candidates

a random sample of middle school kids
a random sample of middle school kids

a random sample of visitors at a museum

Answer 1

the first one i think

Answer 2

The first option…
Use elimination and reasoning.

If you were to ask supporters of one candidate, it would be biased.

Middle school children cannot vote.

Random visitors at a museum could be of any age group or even tourists from other countries, so it would be inaccurate.
