As noted above, tables and charts are effective ways to organize a lot of detailed numbers because the row and column headings or axis and legend labels convey the identity of variables and their units or categories. Complement them by using prose to ask and answer the research question, helping readers understand how the numeric evidence in the table or chart answers the research question under study.

See J.E. Miller, The Chicago Guide to Writing about Numbers (Chicago, 2004), Chapters 1 and 2 for more information about choosing the right tools to suit your task presenting numbers; Chapters 6 and 7 for creating effective tables and charts.
