Common Dissertation Mistakes to Avoid

The recurring errors that cost marks, and how to prevent each one.

7 min read · Written by UK academic writers

Quick Answer

The most common dissertation mistakes are a research question that is too broad, a descriptive rather than critical literature review, an unjustified methodology, mixing results with discussion, weak referencing and leaving the work too late. Each is avoidable with planning and review.

Supervisors and examiners see the same dissertation mistakes repeatedly. Knowing them in advance lets you design them out of your project. Here are the big ones and how to avoid each.

A Research Question That Is Too Broad

Overly broad questions cannot be answered within a dissertation. Fix this early by narrowing your question to something specific and feasible.

A Descriptive Literature Review

Listing studies one by one loses marks. Synthesise and critique sources by theme, and build towards your research gap instead.

An Unjustified Methodology

Choosing methods without explaining why is a frequent failing. Justify every methodological choice against your research questions.

  • Explain why your approach fits your questions
  • Acknowledge limitations of your choices
  • Do not simply describe what you did

Mixing Results and Discussion

Blending findings with interpretation confuses examiners. Keep the results chapter objective and reserve meaning for the discussion.

Weak Referencing and Leaving It Late

Inconsistent referencing risks plagiarism flags, and last-minute writing sacrifices the editing that lifts grades. Reference as you go and build in time to revise.

Key Takeaways
  • Narrow a broad research question early
  • Make the literature review critical, not descriptive
  • Justify your methodology, do not just describe it
  • Keep results and discussion separate
  • Reference consistently and avoid last-minute writing
