Hoping to learn what issues may resonate with voters in the coming election, the campaign director for a mayoral candidate selects one block at random from each of the city’s election districts. Staff members go there and interview all the residents they can find.
What is the population?

What is the sampling frame?
What is the sample?
What is the sampling method?
Any bias present?
Solution :

mayoral candidate.
(c) All voters in the selected block of the
election district.
(d) All voters that the staff members were able to
find in the selected block of the election district.
