Home ranges have been found to vary seasonally for both foxes and coyotes. A study was conducted in a region of central Illinois, in which three red foxes and three coyotes were captured and radio-collared. The animals were tracked throughout the course of a year, and the home range area for each one was recorded (in square miles) at the end of each season.

Carry out a repeated measures ANOVA to determine whether there is a significant difference in the home ranges of the two species.

The Canine data set contains data about the home range area covered by three red foxes and three coyotes each season throughout the course of a year.

These are the variables in the data set:

This data is sample data from SAS Institute Inc.

The Type 3 test for the species effect yields an F statistic of 12.71 with a corresponding p­value = 0.0235. So the data suggests that the species effect is significant, and thus you can conclude that there is a difference in home range areas between foxes and coyotes.
