“You don’t truly understand something until you quantified it. But you understand nothing at all if all you do is quantify.”

The limitation of quantitative data is that it describes what happened but not why or how it happened. As design researchers, we should seek answers to the questions of why by talking to our customers or stakeholders.
Combining quantitative and qualitative research methods is a good rule of thumb. Remember, quantitative and qualitative methods complement one another; they are complementary, not mutually exclusive.
