Desde esta posición se valora, pues, que el enfoque cuantitativo y el cualitativo no son por definición antitéticos. I am having problems with the word antitéticos in the above sentence. Originally I assumed it meant anti-ethical (which doesn't exist, according to my OED - only unethical, which would be poco ético and not antiético) but I am wondering if it actually means that the quantitative and qualitative approaches are not by definition incompatible. Any thoughts would be most welcome! Thanks in advance.
