7.1 Presenting Graphs Effectively
Presenting statistical graphics in a report or presentation is a common task for many JMP users. As such, it is critical that you do this well. By well, we mean that you rely upon the data to tell the story, be succinct, and, most importantly, present an accurate and valid interpretation (visual, numeric, verbal). It helps to keep the following in mind when presenting statistical graphics:
Understand your data and its limitations. Time spent with your data before you present it prepares you for the questions that may emerge.
Focus on the important factors. What columns are core to the problem or question at hand?[*]
[*] How do you determine which variables or columns are most important? The methods described in Chapter 6 help you identify important columns of interest. For example, the Partition platform (Section 6.1) can help you find out which columns are the key factors affecting another variable.
Provide the simplest expression of the data to convey the most complete description of it.
Present graphs accurately. Do not reduce ranges in graphs to magnify changes or increase ranges to hide trends.
Let graphs speak for themselves and avoid using unnecessary background colors or dimensions that distract from the core information you are conveying. Make sure the graph can be seen by your audience.
