Independent variable and dependent variable mathematically define the word independent variable. In mathematics, y=f(x). In this equation, the independent variable is X and the dependent variable is Y. When this equation is applied to psychological research, the independent variable is the factor or condition that guides the change of the cause variable, so the independent variable is regarded as the cause of the dependent variable.
A technical term in dependent variable function. In a functional relationship, some specific numbers will change with the change of another (or several other) numbers, and this change is called dependent variable. Such as Y=f(X). This formula is expressed as: y changes with the change of x.
Introduction to Independent Variables and Dependent Variables From a mathematical point of view, who is an independent variable and who is a dependent variable is just a stipulation. For example, when studying motion in physics, we usually study the relationship between displacement and motion speed and time. Naturally, we should take time as an independent variable.
In fact, if the speed of an object changes with time, speed is a dependent variable and time is an independent variable; But when studying the relationship between displacement and velocity, from a mathematical point of view, velocity is an independent variable and displacement is a dependent variable.
Examples of independent variables and dependent variables 1. The degree of hunger and the amount of food you eat.
2. The beauty of beauty, the flow of your saliva.
The number of 3.3. Money, quality of life.
4. The extent of Jane Doe's surprise and the volume of screaming.
5. Crazy demand for goods, the number of soldiers killed in your wallet.
The above is a brief introduction of independent variables and dependent variables, and I hope it will be helpful to everyone's study.
