Writing a scientific paper is a complex process, and even experienced researchers can make mistakes. Here are some of the most common pitfalls and tips on how to avoid them:

1. Unclear Research Question or Objectives

• Mistake: The paper does not clearly state the research question or objectives, making it difficult for readers to understand the purpose of the study.
• Solution: Clearly define the research question in the introduction and explain its importance. Make sure the objectives are specific, measurable, and aligned with the study's methods and conclusions.
