The purpose of qualititative research is to obtain and gather detailed, long winded, mostly formal information about a certain subject or several subjects. Usually this type of research is full of long words and long sentences.
The purpose of Quantitative research is to obtain and gather statistical information, so this could be anything from numbers, decimels and percentages to views, likes and dislikes. An example of where you can locate this type of information is on video websites such as You Tube. It could be the percentage of people who watch something, or the percentage of people who watch something, as liking something is different to watching something, but they are linked. Some people are massive fans and watch every single episode of a program, whereas others are just casual fans who catch the odd episode here and there.
