The independent variable is one that the researchers either manipulate (such as the amount of something) or that already exists but is not dependent upon other variables (such as the age of the participants).Thank you, {{form.email}}, for signing up.In order to understand how the independent variable is used in experiments, it can be helpful to look at some different examples.There can by all different types of independent variables. The independent variable is the variable that is controlled and manipulated by the experimenter. The two variables are the time (usage of time by how many days per week) and personality trait (either extroverted or introverted). The amount of input the workers have over their work is the independent variable in this example.At the outset of an experiment, it is important for researchers to operationally define the independent variable. For example, in an experiment on the impact of sleep deprivation on test performance, sleep deprivation would be the independent variable. In: Mercer, S. and Ryan, S. and Williams, M. Personality: personality traits as independent and dependent variables Dewaele, Jean-Marc (2012) Personality: personality traits as independent and dependent variables. In other cases, researchers might find that changes in the independent variables have no effect on the variables that are being measured.A researcher wants to determine if the color of an office has any effect on worker productivity. SLA researchers who have integrated psychological variables into their research designs have primarily done so in order to identify the personality …
The relatively limited interest in individual differences in personality and SLA stands in sharp contrast with the field of personality psychology, where several journals focus on individual differences, such as Personality and Individual Differences and Individual Differences in Learning.
The dependent variable is the variable that is measured by the experimenter. In this example, the color of the office is the independent variable.The independent variable (IV) is the characteristic of a psychology experiment that is manipulated or changed by researchers, not by other variables in the experiment.There was an error. The two variables may be related by cause and effect.

Personality. Personality traits as independent and dependent variables In other cases, multiple levels of the IV may be used to look at the range of effects that the variable may have.A business wants to determine if giving employees more control over how to do their work leads to increased job satisfaction. In an experiment, one group of workers is given a great deal of input in how they perform their work, while the other group is not.
Two examples of common independent variables are gender and educational level.
Come up with a hypothesis for what you expect to happen. ; Look at other experiments for examples and identify different types of independent variables. What I'm trying to figure out is which one goes where.
Select independent variables that you think will cause changes in another variable. The independent variables in a particular experiment all depend on the hypothesis and what the experimenters are investigating.Independent variables also have different levels. The wide range of theoretical perspectives and research approaches are unified by a common concern for the practical realities facing teachers and learners, making this book essential reading for anyone with an interest in the psychology of learning a foreign language. In some experiments, there may only be one level of an IV.
Each type of diet that the experimenters look at would be a different level of the independent variable while weight loss would always be the dependent variable.Amanda Tust is a fact checker, researcher and writer with a Master of Science in Journalism from Northwestern University's Medill School of Journalism. The dependent variable is the variable that changes in response to the independent variable.
