The Condor (May 1995) published a study of competition for nest holes among collared flycatchers, a bird species. The authors collected the data for the study by periodically inspecting nest boxes located on the island of Gotland in Sweden. The nest boxes were grouped into 14 discrete locations (called plots). The accompanying table gives the number of flycatchers killed and the number of flycatchers breeding at each plot. The data are saved in the CONDOR file.
a. Calculate the mean, median, and mode for the number of flycatchers killed at the 14 study plots.
b. Interpret the measures of central tendency you found in part a.
c. Graphically examine the relationship between number killed and number of breeders. Do you detect a trend?
