Answer to Question 1

ANS: D
The target population is the group the researcher wants to generalize to and needs the sample to represent.
Usually the researcher cannot practically get members from the entire population, so samples from that part of the population within reach or accessible.
The control group is that part of the sample that does not receive a treatment or intervention.
The sample is the subset of the population that will participate in the study and represent the population.

Answer to Question 2

ANS: D
Network sampling is useful for locating samples difficult or impossible to obtain in other ways. Network sampling takes advantage of social networks and the fact that friends tend to have characteristics in common.
In network sampling, the criteria are carefully defined.
Network sampling is a slow process and can get costly.
There is no guarantee of sample representativeness with network sampling.
