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).
