The definition of a dependent variable is an unfixed quantity whose value is determined by the value of an independent variable.
An example of a dependent variable is n in the math equation n = 6b.
a variable whose value is determined by the value of another variable, as y in y = 5x
- Mathematics A mathematical variable whose value is determined by the value assumed by an independent variable.
- Statistics The observed variable in an experiment or study whose changes are determined by the presence or degree of one or more independent variables.
In mathematics, a variable whose value is determined by the value of an independent variable. For example, in the formula for the area of a circle, A = πr2, A is the dependent variable, as its value depends on the value of the radius (r).
