Independent variable This statistics resource is a stub. Learn how you can help Wikiversity to develop it. 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).

Dependent and independent variables If the dependent variable is referred to as an explained variable then the term predictor variable is preferred by some authors for the independent variable. Variables may also be referred to by their form: continuous, binary/dichotomous, nominal categorical, and ordinal categorical, among others.

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.

- variables are a mix of continuous and categorical variables and/or if they are not nicely distributed (logistic regression makes no assumptions about the distributions of the predictor variables). Logistic regression has been especially popular with medical research in which the dependent variable is whether or not a patient has a disease. For a logistic regression, the predicted dependent variable is a function of the probability that a. particular subject will be in one of the categories (for example, the probability that Suzie Cue has the. disease, given her set of scores on the predictor variables).

- Answer: An independent variable is exactly what it sounds like. It is a variable that stands alone and isn't changed by the other variables you are trying to measure. For example, someone's age might be an independent variable. Other factors (such as what they eat, how much they go to school, how much television they watch) aren't going to change a person's age.

Confusing Statistical Terms #5: Covariate A simple example is a study looking at the effect of a training program on math ability. The independent variable is the training condition–whether participants received the math training or some irrelevant training. The dependent variable is their math score after receiving the training.

Difference Between Dependent Variables and Independent Variables On the other hand, the dependent variable is the one being measured by the researcher in the experiment. It is the variable that shows how strong the effect of the independent variable is. So, ultimately, the independent variable is the one manipulated and its effects are reflected by the dependent variable.

Chapter 1 The Sociological Approach to Social Problems Dependent Variable. In math, dependent variables are those variables, whose values are determined with the help of the independent variable. Dependent variables are the focus of any project and this is influenced by the independent variables.

What is dependent variable? Answer: A variable is an object, event, idea, feeling, time period, or any other type of category you are trying to measure. There are two types of variables-independent and dependent.

Types of Variable Dependent and Independent Variables. An independent variable, sometimes called an experimental or predictor variable, is a variable that is being manipulated in an experiment in order to observe the effect on a dependent variable, sometimes called an outcome variable.

Dependent Variable There may be more than two dependent variables in any experiment. For example, a researcher might wish to establish the effect of temperature on the rate of plant growth; temperature is the independent variable.

Mathematical Relationships in Science Answer: Just like an independent variable, a dependent variable is exactly what it sounds like. It is something that depends on other factors. For example, a test score could be a dependent variable because it could change depending on several factors such as how much you studied, how much sleep you got the night before you took the test, or even how hungry you were when you took it.

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.

- Using our example, the softness of the ice cream responded to changes in the temperature of the freezer. A variable that we purposefully change or manipulate is called the independent variable. The thing that changes in response is called the dependent variable.

- 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.

Dependent and independent variables In mathematical modelling, the dependent variable is studied to see if and how much it varies as the independent variables vary. In the simple stochastic linear model the term is the i th value of the dependent variable and is i th value of the independent variable.

Dependent Variable Definition and Examples 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, the change in the dependent variable is observed and recorded. When you take data in an experiment, the dependent variable is the one being measured. Common Misspellings: dependant variable.

Independent and Dependent Variables Independent and dependent variables are related to one another. The Independent part is what you, the experimenter, changes or enacts in order to do your experiment. The dependent variable is what changes when the independent variable changes - the dependent variable depends on the outcome of the independent variable.

Definitoin of independent variable, dependent variable, and control variable? an independent variable is the variable that u cannot control, such as time, volume, etc. dependent variable is the variable that depends on another variable. usually something like amount of rainfall or something. control variable is the variable that u can control...such as temperature, amount of heat, etc.

Dependent and independent variables Dependent and independent variables. For dependent and independent random variables, see Independence (probability theory). In mathematical modelling and statistical modelling, there are dependent and independent variables. The models investigate how the former depend on the latter. The dependent variables represent the output or outcome whose variation is being studied. The independent variables represent inputs or causes, i.e. potential reasons for variation.

Independent and Dependent Variables A dependent variable? Yes, there can be more than one dependent variable. In our example, for instance, the growth rate of the plants might be one dependent variable and the overall height of the plants might be another dependent variable. Both of these variables depend upon the independent variable.
