 ***Calculation: 1.52 mm<sup>2</sup> (sampling area) / 0.2376 mm<sup>2</sup> (area / FOV ) = 6.40 FsOV.
-*'''RANT''': Sampling 10 fields, where the field of view (FOV) is 0.152 mm<sup>2</sup>, is ''not'' the same as sampling ten fields, where the FOV is 0.312 mm<sup>2</sup>.  It surpring that Elston & Ellis ignore the fact that "10 HPFs" on different microscopes represent different sample areas and that they do ''not'' standardize the sampling area.
+'''STATISTICAL NOTE''':
+Sampling 10 high power fields, where the field of view (FOV) is 0.152 mm<sup>2</sup>, is ''not'' the same as sampling ten fields, where the FOV is 0.312 mm<sup>2</sup>.  It surprising that Elston & Ellis ignore the fact that "10 HPFs" on different microscopes represent different sample areas and that they do ''not'' standardize the sampling area.
