Numbers and data are not just for the sciences, but can be used in the humanities and religious studies. When data is presented in tables or charts, it can be an effective way to make an argument. Consider a sentence like:
Martin Luther King, Jr. wrote many times to federal government officials, but they usually did not take his recommendations.
Not only does such a sentence require evidence in the form of examples and citations, its vagueness makes it a weak argument. "Many," for example, can mean a lot of things; it therefore does not tell the reader too much. Compare this general argument to a more precise one:
Martin Luther King, Jr. wrote to President Kennedy at least six times in the first two years of his term, but the White House usually would not or decided that it could not take King’s recommendations.*

While this is better, the reader could benefit from an explanation of these six instances. While these could be listed, the quantitative quality of the evidence lends itself to being presented in a Table:
Martin Luther King, Jr. wrote to President Kennedy at least six times in the first two years of his term, but the White House usually would not or decided that it could not take King’s recommendations (see Table 1).
The following are the main directions for formatting tables and figures from Chapter 26 of Turabian (Kate L. Turabian, A Manual for Writers of Research Papers, Theses, and Dissertations, 9th ed., ed. Wayne C. Booth, et al. (Chicago: University of Chicago Press, 2018), 370-382).
