fraud

Explanation:

A fraud in research is against the research ethics. It occurs when the researchers frame their conclusions based on the incorrect results purposively. Stealing the results and thesis topic from other author or researcher and publishing by own name is also a fraudulent practice. These fraudulent activities are likely to affect the reliability and validity of the research.
