In other words, an independent variable is a cause while a dependent variable is its effect.
The relationship between dependent and independent variables is either correlation or causation. Often confused, these terms have a subtle nuance. Correlation indicates a statistical relationship between research variables, which necessarily indicates that the change in the value of a variable is actually caused by another variable. On the other hand, causation strictly implies that if the dependent variable value changes, it is because of the...
