What is the explanatory variable and what is the response variable?
❖ The variable that researchers are trying to explain or predict is called the response variable. It is also sometimes called the dependent variable because it depends on another variable. ❖ The variable that is used to explain or predict the response variable is called the explanatory variable.
In regression the dependent variable is known as the response variable or in simpler terms the regressed variable. The independent variable is called the Explanatory variable (or better known as the predictor) – the variable which influences or predicts the values.
What are the explanatory variables in an experiment?
An Explanatory Variable is a factor that has been manipulated in an experiment by a researcher. It is used to determine the change caused in the response variable. An Explanatory Variable is often referred to as an Independent Variable or a Predictor Variable.
Can explanatory and response variables be independently associated?
Thus a response variable corresponds to a dependent variable while an explanatory variable corresponds to an independent variable. This terminology is typically not used in statistics because the explanatory variable is not truly independent. Instead the variable only takes on the values that are observed.
What is a response variable example?
A response variable is the variable about which a researcher is asking a specific question. In our example, the variable was how much Halloween candy you collected. The response variable can be affected by many different factors, known as explanatory variables.
What is an example of an explanatory variable in statistics?
Example: Height & Age The students want to use height to predict age so the explanatory variable is height and the response variable is age.
What is the difference between a response variable and an explanatory variable? A response variable measures an outcome of a study. An explanatory variable attempts to explain the observed outcomes.
What is the difference between a response variable and an explanatory variable provide an example?
Explanatory Variable: Type of fertilizer. This is the variable we change so that we can observe the effect it has on plant growth. Response Variable: Plant growth. This is the variable that changes as a result of the fertilizer being applied to it.
What is a response variable in statistics quizlet?
A response variable measures an outcome of a study. An explanatory variable attempts to explain the observed outcomes. The explanatory variable is usually called independent and the response variable is called dependent. We will rarely use this terminology in stats. You just studied 42 terms!
What does response variable mean in statistics?
In statistics, a response variable, also known as a dependent variable, is a concept, idea, or quantity that someone wants to measure. It depends on an independent variable. A question is proposed, usually stating that the response variable will (or will not) change based on other factors.
What is the difference between response and predictor variables?
Variables of interest in an experiment (those that are measured or observed) are called response or dependent variables. Other variables in the experiment that affect the response and can be set or measured by the experimenter are called predictor, explanatory, or independent variables.
Which of the following best describes the explanatory variable?
Which of the following best describes the explanatory variable? The explanatory variable explains or predicts changes in the response variable.
How do you find the explanatory variable?
However, in the event that there is a response and explanatory variable, then the explanatory variable is always plotted along the x or horizontal axis of a Cartesian coordinate system. The response variable is then plotted along the y axis.
What is manipulated variable and responding variable?
The responding variable is the response of the experimental subject to the manipulated variable. The dependent variable depends on what happens during the experiment. The two terms, responding variable and dependent variable, describe the same aspect of the experiment.
What is an example of an explanatory variable?
The independent variable remains unaffected by other independent variables whereas for the explanatory variables, the variables are not independent. For example, consider the two explanatory variables in an experiment are fast food and soda . Many fast food restaurants encourage having soda after intake of food.
What is an example of a response variable?
A response variable is classified as a dependent variable. An explanatory variable may be compared to an independent variable. For example, a study is done to determine if the number of hours spent doing homework has an effect on the grade a student earns on an exam.
