what is the explanatory variable In some research studies one variable is used to predict or explain differences in another variable In those cases the explanatory variable is used to predict or explain differences in the response variable
An explanatory variable is a type of independent variable The two terms are often used interchangeably But there is a subtle difference between the two When a variable is independent it is not affected at all by any other variables Two of the most important types of variables to understand in statistics are explanatory variables and response variables Explanatory Variable Sometimes

Explanatory variables are the variables that can be altered or manipulated in research for example a change in dosage while response variable is the result of manipulation done to the variables the time it took for the reaction to occur An explanatory variable represents the expected cause that can explain the outcome of the research while response variables represent the effect that is expected as a response to the explanatory variable
The explanatory variable sometimes referred to as a predictor is the variable that we hope explains or predicts our response Finally an association between two variables implies that there is a relationship between two variables where the value of your explanatory variable makes certain values of your response more likely Explanatory Variable Variables that serve to explain changes in the response They may also be called the predictor or independent variables Note A variable can serve as an explanatory variable in one study but response in another Example 1 3 Response and Explanatory Variables Consider the variables Sex Female Male and Height in inches

A scatterplot can be used to display the relationship between the explanatory and response variables Or a scatterplot can be used to examine the association between two variables in situations where there is not a clear explanatory and response variable The explanatory variables are the variables we use to explain variation in the outcome variable Although we will initially consider only one explanatory variable at a time later in this course we will allow for the possibility of using multiple explanatory variables at a time
