Statistical Analysis:
For our predation experiment we compared differences in predation rates
of models placed in urban and natural environments using Chi-square
tests when the assumptions of that test were met. Where the assumptions
of Chi-square tests were not met (i.e. expected values of 0) data were
then analyzed using Fisher’s exact tests. We used two-sample t-tests to
determine differences in color-matching between models and checked for
differences between urban gray and urban red models and ranch gray and
ranch red models.
