Performance standards are used to evaluate what specific, measurable evidence is acceptable in determining whether content standards have been met.

A direct variation, also called direct proportion is a relationship between two variables x and y that can be written as y = kx, k ≠ 0. This situation occurs when the ratio of two variables is constant. When y = kx, we say that y varies directly with x. When z = kt, we say that z varies directly with t.
Inverse Variation Inverse Proportion Inversely Proportional A relationship between two variables in which the product is a constant. When one variable increases the other decreases in proportion so that the product is unchanged.
Combined Variation. Combined variation describes a situation where a variable depends on two (or more) other variables, and varies directly with some of them and varies inversely with others (when the rest of the variables are held constant).
