Design of experiments allows you to identify and eliminate causes of variations.
A relationship between a set of values for one variable and a set of values for other variables is known as a variation. direct modification The function y = mx (commonly written y = kx), which is referred to as a direct variation, can be obtained from the equation y = mx + b if m is a nonzero constant and b = 0.
If y fluctuates in direct proportion to x, then y = kx, where k is a fixed amount known as the constant of variation. Finding k is necessary before using the resulting equation to address variational problems in equations of this type.
