What are the 2 major types of research?

The two main types of research are qualitative research and quantitative research. Qualitative research is descriptive in nature, because it generally deals with non-numerical and unquantifiable things.

What is Design of Experiments with examples?

Design of experiments (DOE) is a systematic method to determine the relationship between factors affecting a process and the output of that process. In other words, it is used to find cause-and-effect relationships. An understanding of DOE first requires knowledge of some statistical tools and experimentation concepts.
