Dissertation questions students ask most
Short answers to the questions that come up before students pick a guide.
Where should I start if I have no dissertation topic yet?
Start with the guide on choosing a dissertation topic, then move to writing a research question. Those two decisions constrain everything that follows, so they are worth getting right before you read widely.
How long should a dissertation literature review be?
Typically 20–30% of the total word count — around 2,000–3,000 words in a 10,000-word undergraduate dissertation and 4,000–6,000 in a 20,000-word master's dissertation. Your handbook overrides any general rule.
What is the difference between aims, objectives and research questions?
The aim states the overall purpose, objectives are the concrete steps that achieve it, and research questions are what your data will actually answer. All three must point in the same direction.
Are these dissertation guides free?
Yes. Every guide in the Learning Centre is free to read without an account.
