Precision is a term that describes the level of repeatability of measurements When collecting a group of data, either by measurement or through an experiment of some kind, the precision describes how closeWhat is the most common method of expressing the precision of a series of repetitive measurement? Standard deviation Mean O Average O Percent yield Question 5 2 pts Calculate the density in g/mL of a liquid with 702 g and 032 L? (Report your value to the second decimal place and do not enter the unit)What is the most common method of expressing the |The precision of a test method is a measure of how variable the method is when used under wellcontrolled conditions It is convenient to express precision by means of the standard deviation of individual measurements The average range within small groups of test measurements can be used to estimate the standard deviationPrecision and Accuracy of Test Methods

• ## Estimating Precision Using Duplicate Measurements

sion of precision is subjectively chosen, and multiple issues must be considered when choosing a method, including whether to express the precision in dimensional or nondimensional terms, what range of concentrations to include in the precision calculations, and how to aggregate measurements made under differing conditionsThis method says that the percent uncertainty in a quantity calculated by multiplication or division is the sum of the percent uncertainties in the items used to make the calculationFor example, if a floor has a length of 400m and a width of 300m, with uncertainties of 2% and 1%, respectively, then the area of the floor is 120 m 2 and hasAccuracy, Precision, and Significant Figures | PhysicsThe term precision is used in describing the agreement of a set of results among themselves Precision is usually expressed in terms of the deviation of a set of results from the arithmetic mean of the set (mean and standard deviation to be discussed later in this section) The student of analytical chemistry is taught correctly that goodAccuracy, Precision, Mean and Standard Deviation
