What is a parameter in programming?
A parameter is a special kind of variable used in a function to refer to one of the pieces of data provided as input to the function. These pieces of data are the values of the arguments with which the function is going to be called/invoked.
What is parameter with example?
A parameter is a quantity that influences the output or behavior of a mathematical object but is viewed as being held constant. … One place parameters appear is within functions. For example, a function might a generic quadratic function as f(x)=ax2+bx+c. Here, the variable x is regarded as the input to the function.

What is a parameter in an experiment?
So in applications the distinction between parameters and variables usually depends on the timescale over which they change: variables are usually the things that change within one experiment or experimental trial, while parameters are the values that change across experiments or experimental trials.
