Decide what question is central to your study. The poster is your medium for delving into the issues surrounding this question. All material contained in the poster should have a connection to the question and that connection should be identifiable by the reader of the poster. Titles of graphs should be descriptive enough that the reader can ascertain the relationship of the graph to the central question. Now that we have made sure that each graph is focused on the central question, let us discuss some features of an effective graph.
Effective graphs draw the reader's attention.
They sell the poster to the reader. The use of color, catchy titles, unique graphical components, etc., adds to the visual appeal of the poster. For example, suppose you collect data on the rebound champion in the National Basketball Association. You might use a histogram to display this data. If so, you might fill in the bars of the histogram with cutout basketballs rather than just coloring in the bars.
