Did you use data, facts or examples properly in your poster?
A poster is usually a mixture of a brief text mixed with Tables and Figures.
Contrary to what you may have heard, not all analyses or results warrant a Table or Figure. Some simple results are best stated in a single sentence, with data summarized parenthetically: “Seed production was higher for plants in the full-sun treatment (52.3 +/-6.8 seeds) than for those receiving filtered light (14.7 ± 3.2 seeds, t=11.8, df=55, p<0.001.)”
Tables present lists of numbers or text in columns, each column having a title or label. 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.
Figures are visual presentations of results, including graphs, diagrams, photos, drawings, schematics, maps, etc. Graphs are the most common type of Figure – they show trends or patterns of relationship.
So, think visually! Choose a poster layout, sketch your organizational plan and identify which formats best convey your message. And remember: every Figure and Table included in the poster must be referred to from the text.
