A consultant planning a survey of elementary school principals in a particular state has lists of the elementary school principals employed in each of the 95 school districts.  The procedure will be to obtain a random sample of elementary school principals from each of the districts rather than grouping all the lists together and obtaining a sample from the entire group. 

Which of the following statements is true?

A)  This is a simple random sample achieved in an easier and less expensive manner than procedures involving sampling from the whole population of principals.  

B)  This is a stratified sample, which may yield comparative information that a simple random sample couldn’t give. 

C)  This is an example of systematic sampling, which can achieve a reasonable sample as long as the original order of the list is not related to the variables under consideration. 

D)  This is an example of proportional sampling based on the actual sizes of the school districts in the total population.

E)  This is a cluster sample in which the entire population was divided into heterogeneous groups called clusters.

10.  ____ 


A consultant conducts a study to find out if spending more hours studying leads to better point scoring by players on basketball teams.  The consultant surveys 70 players, and notes that the 35 basketball players who claim to study the most hours per day have a higher scoring average than the 35 players who study less.  Because of the study results, the coach starts requiring the players to spend more time studying.   

Which of the following statements is true?

A)  There might potentially be a confounding variable responsible for the apparent relationship.  

B)  While this is a controlled experiment, the conclusion of the coach is not justified. 

C)  While this study may have its faults, it still does prove causation. 

D)  To get the athletes to study more, it might be more meaningful to have them put in more practice time on the court to increase their point averages, since higher point averages seem to be associated with more study time.  

E)  No proper conclusion is possible without somehow introducing blinding (blind, or double-blind).
