in that year, and 0 indicating a state has not adopted such a policy. Similarly, in the second and third model, the dependent variable is whether a state adopts PBF or CTI in a given year. It is measured by a binary indicator of whether the state has PBF or CTI in a given year, ...
In science, a variable is a detail or condition that can be controlled or perhaps altered in some way. In scientific investigations, studies are designed that contain three different types of variables: dependent, independent and control.
Science is messy. We like to think of experimentation as a simple process of “change one thing and record what happens,” but in reality, every possible subject of study has dozens of different factors that can impact the results. Thedependent variableis the thing being impacted. ...
In any true experiment, a researcher manipulates an independent variable, to influence a dependent variable, or variables.

This chapter presents the numerical solution of elliptic problems in one dependent variable. A sparse matrix is one in which most of the elements are zero. Finite-difference methods yield sparse matrices that allow special techniques to be used for their solution. An upper triangular matrix is ...
In computing, a dependent variable is any variable whose value, output or functioning depends on two or more independent variables. Advertisements A dependent variable is used in computer programming to represent a value, process, function or entity within the programming paradigm/context/architecture...
In mathematics, a variable whose value is determined by the value of an independent variable. For example, in the functiony=x+ 5,yis the dependent variable because its value is determined by the value ofx. The American Heritage® Student Science Dictionary, Second Edition. Copyright © 2014...
In general, if you are studying the effect of a certain factor or the outcome of an experiment, the effect or outcome is the dependent variable. If you measure the effect of temperature on flower color, temperature is the independent variable—the one you manipulate—while the color of the ...
In graphs, the independent variable is on the X-axis, and the dependent variable is on the Y-axis. A dependent variable is the variable being tested in a scientific experiment. The dependent variable is "dependent" on the independent variable. As the experimenter changes the independent variable...
