WebPrecision is a measure of repeatability, or how much one test result is like another. Accuracy, on the other hand, is whether that result hits the target. Of course, for any … WebPrecision levels vary depending on the analyte and the method. Generally, electrolytes and creatinine have very low CV% indicating very good precision. Enzymes and immunoassays typically have higher CV%. One other rule of thumb is that a method's CV or SD should be <1/8th of the reference range width.

As the integral ∫ − a a f ( x) d x of an odd map is always equal to zero, and the two given formulas also vanish for odd maps, what you discovered for odd monomials is normal. While the two formulas are valid for constant maps, they are not exact for x ↦ x 2. The second one is wrong for x 2 also: ∫ − 1 1 x 2 d x = 2 / 3 ... bing wallpaper icon
