Q3 Random Variables Good Essay Examples A random variable is a function that assigns a numerical value to the outcome of an event in a particular sample space. Random variables quantify observations of the real world; they provide a mathematical means of describing phenomena that may have much variability and about which we may be uncertain. Once a model is attained that well describes the phenomenon, predictions can be made when the phenomenon occurs in the future.

Unformatted text preview: A random variable is any rule that designates a certain number to every possible outcome within a sample space. A random variable is generated by associating each outcome of an experiment with a number by specifying a rule of association. This makes RV useful for describing variability and uncertainty because it provides a channel through which experimental outcomes are converted to a numerical function of the outcomes. And it is through numerical aspects of the data that statistical analysis, such as variability and probability, is made....
