Information technology ( T . I . ) A parameter is a special class of variable . Variables are containers of information in the system. Parameters are variables that are entered into the system directly by the user. This definition should not be confused with that of statistical parameter: in practice, when the user enters a parameter in the program, it is often statistical parameters of some distribution that is alien to the system (averages, maximum or minimum, etc. ) , but the theoretical definition of statistical parameter is different from that of parameter in T. I .
