Answer: The answer is (c) estimate of a variable, as determined through a sample.
Step-by-step explanation: We are given four different options out of which one gives the perfect definition of a parameter.
In mathematics, a parameter is defined as a constant or a variable in a function that determines a particular form of the function but not its general form. For example, f(x) = k x, where 'k' determines only the gradient of the line described by f(x).
In statistics, a parameter is defined as a variable that enters in the mathematical form of a distribution such that the possible values of the variable correspond to different distributions.
Thus, the correct option is (c) estimate of a variable, as determined through a sample.
