Dependent Variable
Pronunciation: /dɪˈpɛn.dənt ˈvɛər.i.ə.bəl/ Explain
A dependent variable is a variable whose value depends
entirely on other
variables.^{[1]}
In
functions,
the dependent variable is the output variable. The
independent variable's
value is the input on which the dependent variable depends.
Figure 1  Graph of f(x) = x^{2}. 
 In figure 1,
f(x) = x^{2}, the output variable is
f(x). One can often tell which is the output variable
when it is by itself on one side of the equation.

Cricket Population 
Year  1992  1994  1996  1998 
Population  2053  1740  2741  2286 
Figure 2: Table representing a function. 
 The table in figure 2
represents
a function. The independent variable is
year. This is because the year exists
independently of the cricket population, and the cricket population is dependent on
the year. The cricket population is the
dependent variable.
