A parameter is a quantity that influences the output or behavior of a mathematical object but is viewed as being held constant. Parameters are closely related to variables, and the difference is sometimes just a matter of perspective.
In the set of equations x = 2t + 1 and y = t2 + 2, t is called the parameter. As the parameter varies over a given domain of values, the set of solutions, or points (x, y), describes a curve in the plane.
A parameter is a number describing a whole population (e.g., population mean), while a statistic is a number describing a sample (e.g., sample mean).
The dependent variable is the variable that is being measured or tested in an experiment.
