Correlatie symbool
In statistics, correlation or dependence is any statistical relationship, whether causal or not, between two random variables or bivariate data. Although in the broadest sense, "correlation" may indicate any type of association, in statistics it usually refers to the degree to which a pair of variables are linearly related. Familiar examples of dependent phenomena include the correlation between t… WebAt the character level, there are several star-like symbols, but the most common are: U+002A ASTERISK “*” is the well-known Ascii character with multiple and vague semantics.In mathematics, it is often used as a unary postfix operator or modifier (e.g., N* denotes the set of natural numbers without zero), and its appearance in most fonts is …
