Research Variables: Dependent, Independent, Control, Extraneous & Moderator The dependent variable is the variable a researcher is interested in. An independent variable is a variable believed to affect the dependent variable. Confounding variables are defined as interference caused by another variable.

Research Variables The key to designing any experiment is to look at what research variables could affect the outcome. There are many types of variable but the most important, for the vast majority of research methods, are the independent and dependent variables. A researcher must determine which variable needs to be manipulated to generate quantifiable results. The independent variable is the core of the experiment and is isolated and manipulated by the researcher. The dependent variable is the measurable outcome of this manipulation, the results of the experimental design.

Independent Variable in Psychology Experiments Updated June 16, 2016. The independent variable is the characteristic of a psychology experiment that is manipulated or changed. For example, in an experiment looking at the effects of studying on test scores, studying would be the independent variable. Researchers are trying to determine if changes to the independent variable (studying) result in significant changes to the dependent variable (the test results).

- A variable is any factor, trait, or condition that can exist in differing amounts or types. An experiment usually has three kinds of variables: independent, dependent, and controlled. The independent variable is the one that is changed by the scientist. To ensure a fair test, a good experiment has only one independent variable. As the scientist changes the independent variable, he or she observes what happens. The scientist focuses his or her observations on the dependent variable to see how it responds to the change made to the independent variable.

Whats the difference between independent and dependent variables? also, theory and hypothesis? Best Answer: The independent variable in an experiment is the variable that YOU change in order to affect the dependent variable. The dependent variable is what is being measured, or what is being affected. For example, If you are testing how the amount of time you leave a sponge in a bowl of water affects the amount of water absorbed, then the amount of time you leave the sponge in is the independent variable, and the amount of water absorbed is the dependent variable.

What Is the Difference Between Independent and Dependent Variables? The two main variables in an experiment are the independent and dependent variable. An independent variable is the variable that is changed or controlled in a scientific experiment to test the effects on the dependent variable. A dependent variable is the variable being tested and measured in a scientific experiment. The dependent variable is 'dependent' on the independent variable. As the experimenter changes the independent variable, the effect on the dependent variable is observed and recorded. For example, a scientist wants to see if the brightness of light has any effect on a moth being attracted to the light.

- The independent variable is something that is hypothesized to influence the dependent variable. The researcher determines for the participant what level or condition of the independent variable that the participant in the experiment receives.

Dependent and independent variables In this function, y is the dependent variable and x is the independent variable. Variable used in an experiment or modelling can be divided into three types:  dependent variable ,  independent variable , or other.he dependent variable represents the output or effect, or is tested to see if it is the effect. The independent variable represents the input or cause, or is tested to see if it is the cause. Other variables may also be observed for various reasons.

Dependent Variable vs. Independent Variable in Marketing An independent variable is an input to a process or analysis that influences the dependent variable. While there can only be one dependent variable in a study, there may be multiple independent variables.n independent variable is an input to a process or analysis that influences the dependent variable. While there can only be one dependent variable in a study, there may be multiple independent variables.

- Independent variable definition. An independent variable is a variable that represents a quantity that is being manipulated in an experiment. A dependent variable represents a quantity whose value depends on those manipulations. In the context of a function, the independent variables are the inputs to the function and the dependent variables are the outputs of the function.

independent variable For example, in a study of the effect of nursing intervention on postoperative vomiting, nursing intervention is the independent variable evaluated by its effect on the dependent variable, the incidence of postoperative vomiting. Also called experimental variable, predictor variable. Compare dependent variable.

Independent, Dependent and Extraneous A variable is anything that can vary, i.e. changed or be changed, such as memory, attention, time taken to perform a task, etc. Variable are given a special name that only applies to experimental investigations. One is called the dependent variable and the other the independent variable. In an experiment, the researcher is looking for the possible effect on the dependent variable that might be caused by changing the independent variable. • Independent variable (IV) : Variable the experimenter manipulates (i.e. changes) – assumed to have a direct effect on the dependent variable. • Dependent variable (DV) : Variable the experimenter measures, after making changes to the IV that are assumed to affect the DV. For example, we might change the type of information (e.g. organized or random) given to participants to see what effect this might have on the amount of information remembered.

- Independent Variable Definition: The “thing” that is used to predict the effect on the dependent variable. As the researcher changes this thing he or she observes what happens to the dependent variable. Example: In a study to determine the effect IQ has on SAT scores, the independent variable is IQ.efinition: Changes in the independent variable caused the changes in the dependent variable. Example: The change in weight as measured by the bathroom scale is due to a change in eating habits and exercise since the last time you stepped on the scale and not due to using a different scale.

Independent Variable in Psychology Experiments 1 In this example, the color of the office is the independent variable.  Researchers want to learn whether listening to fast-paced music helps runners perform better during a marathon. In an experiment, one group of runners listens to fast-paced music while another group listens to slow-paced music.

Dependent Variable in Experiments The dependent variable is the variable that is being measured in an experiment. For example, in a study looking at how tutoring impacts test scores, the dependent variable would be the participants' test scores. In a psychology experiment, researchers are looking at how changes in the independent variable cause changes in the dependent variable.

Identifying & Interpreting Independent & Dependent Variables The first type is the independent variable. This is the variable that is manipulated during an experiment. For example, when experimenting with how fertilizer affects plant growth, the fertilizer is the independent variable because this is the variable that you change.

- Independent Variable. A variable in an equation that may have its value freely chosen without considering values of any other variable. For equations such as y = 3x – 2, the independent variable is x. The variable y is not independent since it depends on the number chosen for x. Formally, an independent variable is a variable which can be assigned any permissible value without any restriction imposed by any other variable.

Whatâs the difference between dependent and independent variables? Dependent variables are the main outcomes or characteristics of interest. In mentoring research, we might think that the program affects youth grades, self-esteem, and delinquency. If so, those factors would be our dependent variables in statistical analysis.

Chapter 3.1 Variables The independent variable is the variable that is different between the groups compared: all the members of one group will have the same level of the independent variable, a second group will have a different level of that same variable, and the same for a 3rd or 4th group, if present. is the independent variable and Y is the dependent variable-the outcome, and Z is the type of subjects represented. A simple example would be: The effects of tomatoes on risk of prostate cancer in Scandinavian men.

dependent variable dependent variable, (in research) a factor that is measured to learn the effect of one or more independent variables. For example, in a study of the effect of preoperative nursing intervention on postoperative vomiting, vomiting is the dependent variable measured to determine the effect of the nursing intervention.
