12. Suppose that a sociologist notices a correlation between the rate of personal bankruptcy filings and the suicide rate. As

bankruptcy is a cause of suicide. What method did the sociologist use in drawing this conclusion?
a. The method of concomitant variation.
b. The method of agreement.
c. The method of difference.
d. The method of residues.
e. The joint method of agreement and difference.
13. Suppose that a homeowner notices a 20 percent increase in the water bill for July. The homeowner traces this increase
to four sources: a running toilet, a dripping faucet, a guest who visited for two days, and a broken sprinkler head. Further
study shows that the broken toilet accounts for 8 percent of the increase, the faucet 2 percent, and the visiting guest 4
percent. The homeowner concludes that the remaining 8 percent is attributable to the broken sprinkler head. What method
did the homeowner use in drawing this conclusion?
a. The method of agreement.
b. The joint method of agreement and difference.
c. The method of difference.
d. The method of residues.
e. The method of concomitant variation.
14. The controlled experiment in science is most closely related to which of Mill’s methods?

e. The method of difference.
15. The correlational method used in the social sciences is closely related to which of Mill’s methods?
a. The method of agreement.
b. The method of residues.
c. The method of concomitant variation.
