A sample evidence-supported claim:

Because researchers in paleontology tend to conduct observational rather than experimental research, most of the articles in Journal X contain lots of highly descriptive information, much of it quantitative. The purpose of many articles is to provide detailed descriptions of new fossil discoveries. For instance, Jones (1998) devotes an entire article to describing in detail the fossil remains of a single pliosaur specimen. The article features quantitative data about the length of various bones, but there were also some qualitative descriptions of the condition of the fossil, and even some speculations about the manner in which the specimen had died. In this article, as in several others that I looked at, the quantitative information seemed to be more important, since it was placed earlier in the paragraphs, was discussed at greater length, and was repeated in tables. The qualitative details, by contrast, seemed to be used merely to “fill in the blanks” or to provide background details to help readers picture the scene.
