Accuracy is also used as a statistical measure of how well a binary classification test correctly identifies or excludes a condition. That is, the accuracy is the proportion of correct predictions (both true positives and true negatives) among the total number of cases examined. [10]
Technical writing is most commonly performed by a trained technical writer and the content they produce is the result of a well-defined process. Technical writers follow strict guidelines so the technical information they share appears in a single, popularly used and standardized format and style (e.g., DITA, markdown format, AP Stylebook, Chicago Manual of Style).
The similar term "science writing" instead refers to writing about a scientific topic for a general audience; this could be by scientists and/or journalists, for example.) Scientific writing is a specialized form of technical writing, and a prominent genre of it involves reporting about scientific studies such as in articles for a scientific ...
Ab initio quantum chemistry methods are a class of computational chemistry techniques based on quantum chemistry that aim to solve the electronic Schrödinger equation. [1] Ab initio means "from first principles" or "from the beginning", meaning using only physical constants [ 2 ] and the positions and number of electrons in the system as input.
False precision (also called overprecision, fake precision, misplaced precision, and spurious precision) occurs when numerical data are presented in a manner that implies better precision than is justified; since precision is a limit to accuracy (in the ISO definition of accuracy), this often leads to overconfidence in the accuracy, named precision bias.
The ACS Style is a set of standards for writing documents relating to chemistry, including a standard method of citation in academic publications, developed by the American Chemical Society (ACS).
All analytical procedures should be validated. Identification tests are conducted to ensure the identity of an analyte in a sample through comparison of the sample to a reference standard through methods such as spectrum, chromatographic behavior, and chemical reactivity. [5] Impurity testing can either be a quantitative test or a limit test.
For example, a spectrometer fitted with a diffraction grating may be checked by using it to measure the wavelength of the D-lines of the sodium electromagnetic spectrum which are at 600 nm and 589.6 nm. The measurements may be used to determine the number of lines per millimetre of the diffraction grating, which can then be used to measure the ...
