Focal females visited demonstrator-exposed dishes more frequently than to control/unexposed dishes.

Boxplots illustrating the cumulative number of observations made across 26 sessions in the first experiment in which a focal female <i>D.melanogaster</i> was observed on the surface of one of 5 different media dishes present in the 36 replicate arenas. The boxes enclose the middle 50% of data (the inter-quartile range, IQR), with the thick horizontal line representing the location of median. Data points> ± 1.5 * IQR are designated as outliers. Whiskers extend to largest/smallest values that are not outliers, indicated as closed circles. The results of a Tukey HSD post-hoc test comparing group mean is indicated by letters, where groups that do not share the same letter are considered statistically different at the α=0.05 level. (PDF)
