If the coefficient of correlation is a negative value, then the coefficient of determination must be positive
From the question, we have
Coefficient of correlation = negative value
This means that:
Coefficient of correlation < 0
As a general rule, we have:
Coefficient of determination = square of coefficient correlation.
This means that the coefficient of determination must be positive
Hence, if the coefficient of correlation is a negative value, then the coefficient of determination must be positive
