Manipulated variable refers to variables in an experiment or testing environment where a variable is manipulated to test for a change in outcomes. Manipulated variables are used in many different scenarios, including computer programming, system testing and drug testing.
Continue ReadingIn computer programming, variables are manipulated by using functions and commands. Addition, subtraction and testing for a value are all types of variable manipulation. You may also manipulate variables when debugging the application to test your error handling or outcomes.
The best example of manipulated variable testing is the use of placebos in drug testing. When measuring the rate of a patient's recovery, the main variable is the medication that is being tested. The variable is manipulated between the patient taking the tested medication, a placebo or an alternative treatment.
Learn more about AlgebraIn a ninth-grade Algebra I course, students learn to solve problems using the foundational rules of mathematical computations, and they learn to solve algebraic expressions to find the values of variables. Some Algebra I problems require students to graph equations and inequalities. The study of equations in Algebra I helps prepare students for the study of functions in Precalculus and Calculus courses.
Full Answer >In math, a function is a statement that contains one or more variables that can be calculated to produce one or more answers. Math functions range from the simple to the complex. Evaluating a function at a particular point is one of the most common ways to solve a math function.
Full Answer >A polynomial function is a mathematical function that consists of one or more variables to which multiple exponents and coefficients are applied. Each combination of variables, exponent and coefficient is called a term. A polynomial does not contain any negative exponents, radical variables or division of any kind, including fractions.
Full Answer >Similar terms in algebra, sometimes referred to as like terms, are terms that contain the same variables raised to the same power. In algebraic expressions, terms cannot be combined unless they are similar terms.
