A vector of observations of variables called regression, intrinsic variables, response variables, measurement variables, standard variables, or dependent variables. This variable is also called a predictor, but it should not be confused with a predictor. The decision as to which variable in the dataset is modeled as a dependent variable and modeled as an independent variable is that the value of one of the variables is caused by another variable or directly influenced by another variable It is based on the assumption that it is received. Or there may be operational reasons to model one of the variables based on other variables, in which case there is no need to guess the causality.

In mathematical modeling, statistical modeling, and experimental science, the value of the dependent variable depends on the value of the independent variable. The dependent variable represents the output or result of the change being investigated. An independent variable, also called a regression quantity in a statistical context, represents a potential cause of input or cause, ie variation. In the experiment, all the variables operated by the experimenter can be called independent variables. Models and experiments test the effect of independent variables on dependent variables. Sometimes, even though their effects are not direct benefits, they may contain independent variables for other reasons, such as considering the potential confounding effects.

Each experiment has two important variables, an independent variable and a dependent variable. An independent variable is a variable whose change is not affected by any other variables in the experiment. Scientists either change their own variables, or they change themselves; there is nothing else to experiment with or influence it. Two examples of general independent variables are age and time. You can neither speed up nor slow down anything else, nor can you raise or lower your age. They are independent from everything else
