"3sigma" or "three sigma" refers to a statistical concept that is used to measure the spread or variability of data. In statistics, "sigma" (σ) is a symbol that representsthe standard deviation(标准差), which is a measure of how much the data values in a set vary from the average ...
句子:"The sigma symbol was carved into the stone pedestal beneath the statue." 翻译:“西格玛符号被雕刻在雕像下方的石基座上。” 出处:《A Brief History of Time》by Stephen Hawking 句子:"In physics, we often use the sigma notation to represent the sum of a series of numbers." 翻译:“在物...
2. The symbol for the standard deviation is a lower case sigma. However the formula for the standard deviation also involves a sum (upper case sigma). Technically we are finding a lower case sigma, but need to use an upper case sigma to do so. 3. To find we first need to find ...
英文:The standard deviation of this data set is σ equals to 2. 中文:在物理学中,σ有时用来表示材料的某种特性。 英文:In physics, σ is sometimes used to represent a certain characteristic of a material. 英文同义表达: “Summation symbol”(求和符号):特指Σ在数学...

在数学求和的上下文中,“Σ”可以解释为“summation symbol”或“sum sign”。 在统计学中,“σ”可以解释为“standard deviation”。 在物理学中,“σ”的具体含义取决于上下文,但可以用具体的物理量或参数名称来替换。
Sigma is the Greek alphabet’s eighteenth letter. The lowercase letter sigma (σ) denotes the standard deviation in math and statistics. In math, the capital letter sigma (Σ) represents to sum it up. How to Insert the Sigma Symbol in Excel: 8 Easy Ways ...
In various fields like statistics, mathematics, and engineering, the sigma symbol (Σ or σ) is frequently used, often representing the sum of a set of terms or as a symbol for standard deviation in statistics. There are two types of sigma symbols: Σ– Greek Capital Letter Sigma σ– ...
Coming full circle, the lowercase Greek letter sigma (σ) transcends the boundaries of mathematics to become a symbol of precision, quality, and continuous improvement in the realm of Six Sigma. Its mathematical roots in standard deviation align seamlessly with the methodology's pursuit of minimizing...
This actual standard deviation has a value dependent on the process data. The number in front the the sigma symbol is called Z. We often refer to it as sigma, as in “what’s your process’ sigma?” This sometimes can create confusion, but should be clear by the end of this session....
