This visual shows the quantitative/qualitative divide in sociology. The obvious difference is the term "data." Qualitative folks downplay data--the single most important element in science, in my view. They like flashy theories and flashy politics. I loathe Freudianism and Marxism, for example, because these schools are indifferent to data.
"I often say that when you can measure what you are speaking about, and express it in numbers, you know something about it; but when you cannot express it in numbers, your knowledge is of a meagre and unsatisfactory kind; it may be the beginning of knowledge, but you have scarcely, in your thoughts, advanced to the stage of science, whatever the matter may be." ~ Lord Kelvin
