Comments by the Judges:
The strength of this poster is that a statistical comparison (t-test) that was appropriate for the research question was done.
Give a brief explanation on the poster regarding pairing for the t-tests. Use 2-D, rather than 3-D histograms, since no data is represented by the 3rd dimension.
