# Statistics

I am trying to understand the meaning of data mining? What is data mining? I'm thinking it's like a huge warehouse that stores data. Is it possible to provide an example? Can you also recommend any literature about data mining?

I would also like to know what type of research situation would use only descriptive statistics? In quantitative only? Is there any published literature I may review from?

What exactly is a regression line and a regression analysis? How can I effectively understand and utilize regression analysis in a research study? Are there any journals or websites I may look at for clarity purposes?

I'm just looking for a better understand of these topics, because the readings seem to technical.
