Abstract:

Tables should allow readers to easily and accurately: see what subject matter and variables are being described; find out absolute values; observe relationships between variables. When you edit a table, it is useful to assess just how well it achieves these ends. Readers will feel confident with your table if they can quickly navigate around and absorb the data.
