The experimental approach is usually to acquire data that accurately quantifies the phenomenon. Heisenberg's uncertainty principle quantifies the inability to precisely locate the particle given its conjugate momentum. The entropy quantifies these considerations when a probability distribution of the source data is known. Hence the measurement quantifies the stoichiometry of the complexes as well as kinetics. It quantifies the severity of multicollinearity in an ordinary least squares regression analysis. Richness simply quantifies how many different types the dataset of interest contains. This equation numerically quantifies how desirable the material will be for a specific situation. The relative turbidity of the reacted sample quantifies the CYA concentration. The Shannon entropy quantifies the uncertainty (entropy or degree of surprise) associated with this prediction. It quantifies the extent to which a sample diverges from expectations. Citation impact quantifies the citation usage of scholarly works. The emittance of an object quantifies how much light is emitted by it. Single-cell DNA methylome sequencing quantifies DNA methylation. This unit only quantifies the visible radiation, and excludes invisible infrared and ultraviolet light. Young's modulus quantifies the elasticity of the polymer.
