Question

Researchers are interested in finding out if voters are more likely to vote for congressional candidates who have more pleasant facial expressions. Starting at a random point, the researchers contact every hundredth person on the voter list to ask about candidate facial expressions. Which method are the researchers using in choosing the people they will call?

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.
