Tables and Figures in Research Papers - Writing Tips and Examples

Tables and figures belong in a research paper’s results section whenever the information can’t be communicated clearly in a short stretch of text. A practical rule of thumb guides placement: if the data and the surrounding explanation can’t fit into one or two lines, it’s usually better to move the content into a figure or table. That shift matters because it improves readability—especially for readers scanning for evidence—while keeping the narrative focused on interpretation rather than dense reporting.

Choosing between a figure and a table depends on what the reader needs to take away. Figures are best for illustrating trends and patterns, such as changes over time or relationships between variables. Tables are better when the goal is to present actual values or pack in substantial numerical detail. In a typical results-writing approach, authors first describe the trend in the text, then repeatedly point readers to the relevant figure as the evidence for each claim. The final step often clarifies where the exact numbers live—usually in a table—so readers who want to verify or reuse the data know where to look.

Once figures and tables are included, they must be integrated into the writing rather than left as standalone objects. Every figure or table needs an in-text reference; a paper shouldn’t contain a visual element that isn’t discussed in the surrounding narrative. Captions also carry responsibility. Because many readers skim through figures and tables, captions should be as short as possible while still explaining what the item shows. The caption should function as a quick orientation, not a replacement for interpretation.

A common writing error is repeating the caption verbatim in the text. If the text merely restates what the caption already says—such as “the figure shows the change in temperature over time”—it adds no new information. A stronger approach is to use the reference to add value: highlight an interesting trend, interpret what the reader should notice, or connect the visual evidence to the paper’s argument. This keeps the results section crisp and concise by cutting unnecessary repetition and focusing on what the data means.

Overall, effective results writing treats figures and tables as evidence that supports specific claims. The narrative should point to the visual, interpret what it reveals, and direct readers to the exact data when needed—without duplicating caption text or leaving visuals unaddressed.
