Fig. 2. Measurements for IRT eye temperatures (red) and rectal temperatures (blue) on 73 Angus steers. The dashed black lines are the theoretical normal distributions for
each of the data sets. The grey dashed line centered at 38.2 C is the imagined IRT eye temperature of a fevered population of cattle using the standard deviation of IRT
measurements and the possible increase of a rectal measurement. The inset is the Q–Q plots for the distributions, both showing excellent normality with R2 values of 0.98 for
both distributions. (For interpretation of the references to colour in this figure legend, the reader is referred to the web version of this article.
