Question

Researchers are interested in finding out if voters are more likely to vote for congressional candidates who have more pleasant facial expressions.

Answer 1

Answer:

Random Sample

Explanation:

The Random Sample is a method that consists of randomly selecting a portion (a sample) from a population that is being studied, in order to collect specific data from that population. Such a representative sample is meant to be unbiased because all individuals have the same opportunity of being chosen (they are chosen by chance). Therefore, when, starting at a random point, researchers contact every hundredth person on the voter list to ask about candidate facial expressions, they are using the Random Sample technique.
