The independent variableis the variable that is controlled and manipulated by the experimenter. For example, in an experiment on the impact of sleep deprivation on test performance, sleep deprivation would be the independent variable. The dependent variable is the variable that is measured by the ex...
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)psycholstatisticsthe variable measured by the experimenter. It is controlled by the value of the ind...
Variable is the stimulus, phenomenon, or characteristic that can be varied, operated, or measured in nature or quantity, and is the logical starting point of psychological experiments. In order to study the relationship between various psychological phenomena and influencing factors, variable operations ...
In an experiment, the factor manipulated by the experimenter is called the: A. dependent variable B. extraneous variable C. independent variable D. experimental control A researcher is interested in the effect of study method on test scores. In this hypothetical research question the test score is...

an experiment. Quite simply, theindependent variableis the state, condition or experimental element that is controlled and manipulated by the experimenter. Thedependent variableis what an experimenter is attempting to test, learn about or measure, and will be “dependent” on the independent variable...
1. Theinteracting effect of a variable on the relationship between the independentand the dependent variables. What is the meaning of independent and dependent variables? The independent variable is the variable the experimenter manipulates or changes, and is assumed to have a direct effect on the ...
What is the most crucial difference between experimental and non-experimental research regarding variables and validity? (Provide an example of the approach.) How does an observational study differ from a controlled experiment? In an experiment, the factor manipulated by the experimenter is called the...
An independent variable is defined as a variable that is changed or controlled in a scientific experiment. The independent variable represents the cause or reason for an outcome. Independent variables are thevariables that the experimenter changesto test his or herdependent variable. A change in the...
The independent variable, controlled by the experimenter, influences the dependent variable, which responds to changes. This dynamic forms the basis of cause-and-effect relationships. Graphing independent and dependent variables follows a standard method in which the independent variable is plotted on the...
