dependent variable

1. Mathematics A mathematical variable whose value is determined by the value assumed by an independent variable.
2. Statistics The observed variable in an experiment or study whose changes are determined by the presence or degree of one or more independent variables.

dependent variable

1. (Mathematics) a variable in a mathematical equation or statement whose value depends on that taken on by the independent variable: in "y = f(x)", "y" is the dependent variable.
2. (Psychology) psychol statistics the variable measured by the experimenter. It is controlled by the value of the independent variable, of which it is an index

depend′ent var′iable

a variable in a functional relation whose value is determined by the values assumed by other variables in the relation, as y in the relation y= 3x2.

de·pen·dent variable

In mathematics, a variable whose value is determined by the value of an independent variable. For example, in the function y = x + 5, y is the dependent variable because its value is determined by the value of x.

First, the correlation relationship between the dependent variable and independent variables are tested and then regression method is used to determine the mathematical relationship between dependent and independent variables.
The research team builds a multi factor regression model by first identifying the correlation (whether linear or non-linear) between the dependent and independent variables.
Howerver, we have to keep in mind that the coefficient can only show the intensity in regressions and correlations, which places a great deal of responsibility to the researcher when choosing his/her working dependent and independent variables.
