Anion gap: A measurement of the interval between the sum of routinely measured cations minus the sum of the routinely measured anions in the blood. The anion gap = (Na+ + K+) - (Cl- + HCO3-) where Na-is sodium, K+ is potassium, Cl-is chloride, and HCO3- is bicarbonate.
Precision: Precision refers to the reproducibility of this result that is you get the same result every time you try. Characteristics of Accuracy and Precision: Accuracy: Accuracy refers to the closeness of a measurement to its actual or real value. Precision: Precision refers to the regularity of obtaining the same result frequently. Usage: Accuracy: The concept of accuracy is encountered in measurement in physics and industry.
Accuracy is how close a result is to the. âtrueâ value. Using a target as an example, accuracy. is how close your shot is to the center. of the bullâs eye. The three shots on the. target are close to the center but a little. biased to the right. âBiasâ is a word used. to describe or indicate how far you are.
