In statistics and research methodology, a response variable is the primary outcome or result measured in an experiment or study; it's the variable whose values are expected to change as a result of manipulations to one or more explanatory (independent) variables.
Also known as a dependent variable or outcome variable, it represents the effect or output in a cause-and-effect relationship being investigated. In data modelling, it is the target variable that a model attempts to predict or explain.
