What is response variable and explanatory variable?
The difference between explanatory and response variables is simple: An explanatory variable is the expected cause, and it explains the results. A response variable is the expected effect, and it responds to other variables.
What is the explanatory and response variable example?
Example: Height & Age A group of middle school students wants to know if they can use height to predict age. The students want to use height to predict age so the explanatory variable is height and the response variable is age.
Is the predictor variable The explanatory variable?
Explanatory Variable A predictor variable in a model where the main point is not to predict the response variable, but to explain a relationship between X and Y.
What is the difference between predictors and variables?
Predictor variable and independent variable are both similar in that they are used to observe how they affect some other variable or outcome. The main difference is that independent variables can be used to determine if one variable is the cause of changes in another, whereas predictor variables cannot.
What is a predictor variable?
Predictor variable is the name given to an independent variable used in regression analyses. The predictor variable provides information on an associated dependent variable regarding a particular outcome. At the most fundamental level, predictor variables are variables that are linked with particular outcomes.
What is a explanatory variable example?
An explanatory variable is a type of independent variable. When a variable is independent, it is not affected at all by any other variables. When a variable isn’t independent for certain, it’s an explanatory variable. Let’s say you had two variables to explain weight gain: fast food and soda.
What is predictor and response?
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.
What are response variables?
Response variables are defined as outcomes that will be used as the main evidence of the treatment effect of the investigational drug. Treatment effect is defined as an effect that is expected to result from a therapy.

What’s a predictor variable?
Which is the explanatory variable?
❖ The variable that is used to explain or predict the response variable is called the explanatory variable. It is also sometimes called the independent variable because it is independent of the other variable. In regression, the order of the variables is very important.
What is meant by explanatory variable?
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.
