What do we call the subset of a group that are singled out to give an opinion that represents the group?

Question

a. bias

b. sample

c. population

d. census

e. none of these

please help me out~

thanks, much appreciated

Answer 1

This is an educated guess, but I would say b. It's a sample of a larger group. Very much like pollsters can tell you that particular states vote either Democratic or Republican. As I say, it's an educated guess.

From My Oxford Dictionary:  "Sample"  Small representative part or quantity.  

Answer 2

i think its D. Census.

cen·sus   –noun 1. an official enumeration  of the population, with details as to age, s*x, occupation, etc.

if thats not a close enough definition, then the answer would be E.

Answer 3

B. Sample.  

Answer 4

b. sample

a sample is a subset of the population (group) in question.

GOOD LUCK!
