- Have an idea or causal theory that directs the gathering and assessment of evidence. Follow these tips:
- put data in an appropriate context for assessing cause and effect
- make good quantitative comparisons including examining why something did not occur
- consider alternate explanations
- assess possible errors

- Multiples are useful when analyzing multi-variable processes. Allows for the combination of detail and overview on one display. Combine multiples with narrative text and images for monitoring data-rich processes. [Visual Explanations, page 110. emp]
- Graphic displays should have simplicity of design and complexity of data. This makes comprehension easier, while still maintaining a large amount of data. Avoid unnecessary symbols and decorations, while showing detail. [ The Visual Display of Quantitative Information, page 177. emp]
- Avoid “cherry-picking” by presenting data in a way that is not skewed for a specific benefit. Ask questions such as, “Do the findings grow from the evidence or from the process of evidence construction?”, “Would the process survive a research audit?”, and “Are the findings too good to be true?” [ Beautiful Evidence, page 144-147. emp]
