If all the values of an independent variable x are equal, then regressing a dependent variable y on x will result in a coefficient of determination of zero.
Coefficient of Determination
A statistical measure, often denoted as R-squared, that represents the proportion of the variance in the dependent variable that is predictable from the independent variable(s).
Independent Variable
A variable in an experiment or analysis that is manipulated or categorized to observe its effect on a dependent variable.
Dependent Variable
The variable in an experiment that is expected to change as a result of manipulations of the independent variable.
