Compare and contrast variables and constants?
In Computer Programming and Mathematics, variables and constants are ways to refering to a value. For example X=1 and Y=2 The difference being, variables are meant to be arbitary and changable, while constants are meant to be fixed and unchangable. For example, there is no reason for the value of Pi to change. So the value of Pi would best be represented by a constant.
What is the underlying principle of a chi square test?
The underlying principle is that the square of an independent Normal variable has a chi-square distribution with one degree of freedom (df). A second principle is that the sum of k independent chi-squares variables is a chi-squared variable with k df.
What is meant by mathematical model in particular linear programming model?

What is the differecnce between independent variables and dependent variables?
