Should you research urban renewal or family policy and child care, for instance, and write up what you find, your write-up would be informational. Take a typical college paper. You are asked to write a paper analyzing, say, the impact of changes in immigration laws on poverty. Having broken the subject into some of its parts, you would proceed by discussing each in a paragraph or perhaps a cluster of paragraphs. All of this is what analysis entails.
Analytic prose incorporates a good deal of information.
Certainly, the hypothetical paper on the impact of immigration law on poverty would encompass as many facts as any purely informational essay. But analytic prose is different in purpose from straight informational prose. The purpose of analytic prose is not merely to set forth facts but also, by way of facts, to uncover and clarify meaning. In other words, when writing an analysis, one brings factual material to bear for the purpose of discovering and then backing up an interpretation. For this reason, analytic prose is more complex than informational.
