What are explanatory and explained variables?
❖ 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 an experimental study, the explanatory variable is the variable that is manipulated by the researcher. Explanatory Variable.

What is explanatory variable and response variable examples?

These changing quantities are called variables. A variable is any factor, trait, or condition that can exist in differing amounts or types. An experiment usually has three kinds of variables: independent, dependent, and controlled.
What is the difference between explanatory variable and response variable?
The response variable is the focus of a question in a study or experiment. An explanatory variable is one that explains changes in that variable. It can be anything that might affect the response variable.

What are types of variables in statistics?
Introduction to Types of Variables in Statistics Such variables in statistics are broadly divided into four categories such as independent variables, dependent variables, categorical and continuous variables. Apart from these, quantitative and qualitative variables hold data as nominal, ordinal, interval and ratio.
What are the two types of variables in statistics?
Variables may be classified into two main categories: categorical and numeric.
Is time an explanatory variable?
Time is a common independent variable, as it will not be affeced by any dependent environemental inputs. Time can be treated as a controllable constant against which changes in a system can be measured.
