Comparison of counting methods
Confidence intervals of 95% (95%CI) explain whether the values differ
from zero for the intercept and from 1 for the slope. For all methods
except one – the Photoshop automatic count – 95% CI includes zero.
Hence, there is no significant difference between the intercept value
and the zero value, and there is no consistent difference between these
methods. Likewise, if 95%CI for the slope includes the value one, there
cannot be a significant difference between the slope and unity, and
there is no proportional difference between the methods. As with the
intercept, all the methods meet this assumption, except the Photoshop
automatic count (Table 4, Fig.2).
