Chapter 3.2 Independent Variables 1 The independent variable DRUG would be an active independent variable. An attribute independent variable occurs when groups are compared, but the grouping variable cannot be chosen and manipulated by the investigators because it is a characteristic of the subjects themselves.Example 7: One example of an attribute variable is gender.here may be up to 3-5 groups per variable, but usually not more than that. Example 4: If a study is comparing two types of treatments: a placebo and an experimental treatment, the independent variable is treatment and it has two levels: placebo and experimental.

If a scientist conducts an experiment to test the theory that a vitamin could extend a person's life-expectancy, then the independent variable is the amount of vitamin that is given to the subjects within the experiment.

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 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.

- Some researchers observe what changes occur while they are passive to determine the dependent variable. In these cases, researchers merely record the measurements and results of the dependent variable without interference. Conversely, the independent variable is thought to be the variable acted upon.Active independent variables require researchers to act, such as adjusting a temperature or dose.n these cases, researchers merely record the measurements and results of the dependent variable without interference. Conversely, the independent variable is thought to be the variable acted upon. Active independent variables require researchers to act, such as adjusting a temperature or dose.

Dependent Variable vs. Independent Variable in Marketing The dependent variable -- also called the response variable -- is the output of a process or statistical analysis. Its name comes from the fact that it depends on or responds to other variables. Typically, the dependent variable is the result you want to achieve.

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.

What is an input variable, outcome variable and fixed variable? A dependent variable is also known as a response variable, regressand, predicated variable, measured variable, explained variable, experimental variable, responding variable, outcome variable, and output variable.

Independent Variable The term independent variable is often a source of confusion; many people assume that the name means that the variable is independent of any manipulation. The name arises because the variable is isolated from any other factor, allowing experimental manipulation to establish analyzable results.

Independent variable Independent variable. An independent variable is used in statistics to predict or explain a dependent variable. For example, Age and Gender might be used as independent variables to predict the age of death or life expectancy (dependent variables). In experimental designs, the independent variables are manipulated by the researcher (e.g., different dosages of a drug).

Independent Variable Definition and Examples Definition: An independent variable is the variable that is changed or controlled in a scientific experiment. Independent variables are the variables that the experimenter changes to test their dependent variable. The effect on the dependent variable is measured and recorded. Common Misspellings: independant variable.

Dependent Variable vs. Independent Variable in Marketing The dependent variable -- also called the response variable -- is the output of a process or statistical analysis. Its name comes from the fact that it depends on or responds to other 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.

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.

- Variables are usually denoted by X and Y. The independent variable is identified as the X-variable and is plotted on the X-axis or abscissa of a graph, and the dependent variable is defined as the Y-variable and is plotted on the Y-axis or ordinate.

- LINK / CITE ADD TO WORD LIST. noun. The definition of an independent variable is a factor that does not change in value based on other factors. An example of an independent variable is a temperature that stays constant during a science experiment.

Independent and Dependent Variables Independent Variables are changes that occur in an experiment that are directly caused by the experimenter (you.) Dependent Variables are changes that occur due to independent variables. A Controlled Variable is anything else that could influence the dependent variables.

What Is the Difference Between Independent and Dependent Variables? The dependent variable is the primary object of study in any experiment, and it does not change throughout the course of the experiment. Different independent variables may be used throughout the course of an experiment to determine what impact, if any, the change has on the dependent variable.

variable variable, independent, n the variable being studied that is manipulated or controlled by an experimenter. In a drug study an investigator may give several doses of a drug (independent variable) to determine the most effective, symptom-reducing (dependent variable) level.

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.

dependent variable Definition. A factor or phenomenon that is changed by the effect of an associated factor or phenomenon called the independent variable. For example, consumption is a dependent variable because it is caused and influenced by another variable: income.

Difference Between Dependent and Independent Variables The variable that is manipulated in an experiment by the researcher is called independent variable. Basically, independent variables are those assumed values which have direct impact on dependent variables and have power to influence them.

Graphing: independent and dependent variables Dependent Variable: A dependent variable is what you measure in the experiment and what is affected during the experiment. The dependent variable responds to the independent variable. It is called dependent because it depends on the independent variable. In a scientific experiment, you cannot have a dependent variable without an independent variable. Example: You are interested in how stress affects heart rate in humans. Your independent variable would be the stress and the dependent variable would be the heart rate.
