Explanatory Variable Response Variable. So to simplify things we identify one of the variables as the response variable and the other as the explanatory variable. In statistics researchers are often interested in understanding the relationship between one or more explanatory variables and a response variable. Learn about explanatory and response variables and learn about correlationIf you found this video helpful and like what we do you can directly support us. Its hard to keep track of which variable is which.
An Explanatory Variable is often referred to as an Independent Variable or a Predictor Variable. Then when describing the relationship its always a matter of describing the response. In those cases the explanatory variable is used to predict or explain differences in the response variable. Then when describing the relationship its always a matter of describing the response. These variables are known as covariates. A response variable measures an outcome of a study.
In an experimental study were typically interested in how the values of a response variable change as a result of the values of an explanatory variable.
Frequently when looking at the relationship between two variables we consider the distribution of a response variable also known as a dependent variable for each value of an explanatory variable also known as an independent variable. In statistics researchers are often interested in understanding the relationship between one or more explanatory variables and a response variable. A response variable measures an outcome of a study. Sometimes referred to as an independent variable or a predictor variable this variable explains the variation in the response variable. Explanatory and Response Variables Interested in studying the relationship between two variables by measuring both variables on the same individuals. Explanatory Variable An Explanatory Variable is a factor that has been manipulated in an experiment by a researcher.
