As the explanatory variable increases, the response variable increases
Is age a independent variable?

What describes the variable that is changed to test the prediction?
The independent (or explanatory) variable is changed to test the prediction,
What is another name for independent variable?
independent variable called also predictor variables,explanatory variables,manipulated variables etc.
A researcher performing an experiment introduces changes in an response variable and tries to explain or bring about resulting changes in the explanatory variable?

What is casual forecasting?
Casual forecasting is mainly concerned with finding a cause-effect relationship between the explanatory variables and the variable to be predicted. After a proper relationship is identified the independent variable can be forecasted by using the future values of the explanatory variables.
Does an observational study or a designed experiment allow the researcher to claim causation between and explanatory variable and a response variable?
designed experiment
