A Dependent Variable!
A variable.
Heat which causes a change in temperature of substance is called specific heat.
Usually this is called the DEPENDENT VARIABLE (DV, aka outcome, criterion...). The scientist manipulates the independent variable and it is their HOPE that the dependent variable will change in response.
It is called the x-variable. It can be the independent variable but there may be no independent variable.
A Dependent Variable!
If x causes changes in y, for example 23x3 =y then x is the independent variable and y is the dependent variable.
The independent variable is the variable that you change and manipulate in an equation. This causes the dependant variable to change.
The independent variable is also called an experimental variable. It is the variable being manipulated in the experiment in order to show the effect on the dependent variable. The dependent variable is also called the response variable. It is the variable being observed in the experiment. A change in the independent variable is what causes the change (if any) in the dependent variable, which is the purpose of the experiment.
an independent variable
The dependent variable is dependent on the independent variable, so when the independent variable changes, so does the dependent variable.
independent variable
controlled variable
A variable that causes change in the output of a system. In a RC circuit, for example, the input V is the excitation variable
Constant variable
Sometimes
The independent variable, because it isn't affected by the other factors.
