Accuracy Of The Data

Understanding accuracy of the data requires examining multiple perspectives and considerations. Accuracy, Precision and Analytical Measurements. Three main factors affect the accuracy and the precision of a measurement: the quality of the equipment we use to make the measurement, our ability to calibrate the equipment, and our skill using the equipment. Accuracy, Repeatibility and Linearity - Yokogawa. Additionally, the accuracy, repeatability, and linearity of an instrument or sensor are pre-determined by (laboratory) testing and mentioned in their datasheets. That means each will have its own error and spread of that error.

Accuracy Guide - METTLER TOLEDO. The pH buffer solutions used for calibration are traceable to accepted standards (e.g. NIST) with a given accuracy and therefore ISM pH sensors can be specified as sensors with a defined accuracy.

Measurements and Units Accuracy, Precision, and Errors. Accuracy refers to how close a measured value is to the real or “true” value. Building on this, precision refers to the degree of reproducibility of a measured quantity–the closeness of agreement when the same quantity is measured several times–how close the measurements are to each other. Accuracy, Precision, and Significant Figures.

Additionally, accuracy and precision - Basic Knowledge 101. Precision is a description of a level of measurement that yields consistent results when repeated. It is asso-ciated with the concept of "random error", a form of observational error that leads to measurable values being inconsistent when repeated. Similarly, accuracy, precision, and resolution in weight measurements.

The accuracy of a scale is a measure of the degree of closeness of the average value of an object’s displayed weight to the object’s actual weight. If, on average, a scale indicates that a 200 lb reference weight weighs 200.20 lb, then the scale is accurate to within 0.20 lb in 200 lb, or 0.1%.
