Many times I have seen these words "research" and "survey" in newspapers. Like
a research shows that... or
a study shows that... or
a survey conclude that...
From these statements it is not clear that what is the difference between the words
Previously I was thinking that research is a scientific word where as survey is a non-scientific word. Also I thought that survey is done over a large group whereas research is done over a small group.
Please help me in understanding the basic difference between these words.
