Hoping to learn what issues may resonate with voters in the coming election, the campaign director for a mayoral candidate selects one block from each of the city's election districts. Staff members go there and interview all the adult residents they can find.
Identify the following items (if possible). If you can't tell, then say so—this often happens when we read about a survey.
a) The population
b) The population parameter of interest
c) The sampling frame
d) The sample
e) The sampling method, including whether or not randomization was employed
f) Who (if anyone) was left out of the study.
g) Any potential sources of bias you can detect and any problems you see in generalizing to the population of interest
