WebThe following definition formally defines a continuous random variable. Definition A random variable is said to be continuous if it can assume an uncountable number of values. A function, f (x), defined over the set of all real numbers, is called a probability density function (pdf) of the continuous random variable, X, if and only if. WebContinuous variable [ edit] A continuous variable is a variable whose value is obtained by measuring, i.e., one which can take on an uncountable set of values. For example, a variable over a non-empty range of the real numbers is continuous, if it can take on any value in that range. The reason is that any range of real numbers between and with ...
