Do all research project include abstract and rationale?

Most research projects include an abstract and a rationale, but it can vary depending on the format and requirements of the specific project. An abstract provides a concise summary of the research, while the rationale explains the significance and purpose of the study. These components are particularly common in formal reports, theses, or academic papers, but may not be present in informal or shorter projects. Always check the guidelines of the specific assignment or publication to determine the necessary components.
