Question

Mill’s methods claim that if two or more cases share the same effect and share only one common characteristic, then this characteristic may be related to the cause of the effect. Which of Mill’s methods does this describe?
a. Method of agreement
b. Method of concomitant variation
c. Method of difference
d. Joint method of agreement and difference

Answer 1

The correct answer is this one: "d. Joint method of agreement and difference." Mill’s methods claim that if two or more cases share the same effect and share only one common characteristic, then this characteristic may be related to the cause of the effect. Since the outermost electrons determine chemical properties, those with the same number of valence electrons are grouped together.
