WebThe Greek letter sigma was derived from the Phoenician letter šīn, meaning tooth. The small letter sigma (σ) is used to represent standard deviation in math and statistics. It is also used to show syllable in linguistic, a shielding constant in chemistry and sum of divisors in math. The capital letter sigma (Σ) means to sum up in mathematics. WebSix Sigma Background. Six Sigma is a quality management strategy that categorizes process capability by evaluating how many process standard deviations can fit within the tolerance limits of the process. The more standard deviations – or sigmas that fit between the mean of the process and the tolerance limits, the more robust the process will be.

WebSigma (σ) bonds are strong covalent bonds that occur when atomic orbitals overlap. When the atomic orbitals overlap to create a bond, the electrons are shared creating electron density between the nucleus of each atom. The location of the electron density is the σ bond. A single bond is made of one σ bond. WebMay 9, 2024 · 5.3: Sigma Bonding.
