Define Qualitative Research

Since English is not my first language, I often have to research extra for vocabulary that I don't use or hear often. When I saw the word "Qualitative" I thought of "quality", but as I was reading the texts, I figured out it was a littl more then just that simple meaning.
I came across this on wikipedia (I know, it's not a reliable source, but still helpful) and really helped me put understand, since it broke it down for me in an easy way.

I hope this can help someone else as well.
