Validation and communication of research findings constitute the subject matter of chapter 11. Broadly divided into three parts, this chapter first takes up issues of validating the research findings using different criteria and procedures for validation like triangulation, use of a subset of the original data for testing validity of results obtained from the training data sub-set, matching against findings of comparable research etc. Problems in communication of research findings are discussed in the second part, while the third part deals with the preparation of research reports and research papers for publication in journals of repute.
