Do not use a table when you wish to show a trend or a pattern of relationship between sets of values - these are better presented in a Figure. For instance, if you needed to present population sizes and sex ratios for your study organism at a series of sites, and you planned to focus on the differences among individual sites according to say habitat type, you would use a table.

However, if you wanted to show us that sex ratio was related to population size, you would use a Figure. Figures are visual presentations of results, including graphs, diagrams, photos, drawings, schematics, maps, etc. Graphs are the most common type of figure and will be discussed in detail; examples of other types of figures are included at the end of this section.

Once you have done your analyses and decided how best to present each one, think about how you will arrange them. Your analyses should tell a "story" which leads the reader through the steps needed to logically answer the question s you posed in your Introduction.

Four trees fell during the storm and were excluded from the post-storm survey. In the examples later in this section, note the completeness of the legends.
