The main contents of literature analysis method include: analysis and research on the relevant files found, analysis and research on the personal diaries, notes and biographies collected, and analysis and research on the published books and periodicals collected.
The definitions and differences between literature analysis and data analysis are as follows:
Literature analysis is a common research method in thesis writing, and literature analysis is a form of qualitative research. Researchers explain the collected literature around a theme to express their views. In this analysis method, literature can be mainly divided into three categories: public information, private documents and various physical evidence, leaflets, posters, brochures and so on.
Data analysis is a different research method, which is relative to field investigation. It is also called indirect investigation, indoor investigation and copywriting investigation. Such as questionnaires, interviews, etc.
Literature analysis usually uses existing written materials for analysis. In order to improve the reliability of the argument and reduce the potential deviation of the research results, the references used usually need to use at least two different data sources and methods. But even so, we are easily influenced by "prejudice" when writing a thesis.
Data analysis methods also have obvious shortcomings. Usually, the collected data serve the central topic, while the second-hand data can't fully meet our investigation purpose, so there may be many useless parts, or the key content of its analysis is far from our topic.
