In Chapter 2, we introduce data sampling, accuracy, and precision using digital image analysis of carnivore skulls. 

Contained within this lesson is the link to Chapter 2 and the needed image files of bobcats, coyotes, and kangaroo rats. The Carnivores_TrueValue.xlsx file contains estimated mean canine lengths of each carnivore to be used as population parameters or "true values".
