Introduction
Writing a thesis or dissertation is often the most challenging academic task a student undertakes. Many students struggle not because they lack intelligence, but because they fall into predictable traps that delay progress and compromise quality. Here are the 10 most common mistakes and how to avoid them.
Mistake 1: Vague or Overly Broad Research Question
A question like "What is the impact of technology on education?" is too broad to be answerable. Narrow your focus using the PICO or SPIDER framework. A better question: "What is the effect of tablet-based learning on mathematics achievement among primary school students in urban India?"
Mistake 2: Inadequate Literature Review
Many students either cite too few sources or fail to synthesize the literature critically. A good literature review identifies the gap your research fills, organizes studies thematically rather than chronologically, and critically evaluates methodology rather than just summarizing findings.
Mistake 3: Choosing the Wrong Study Design
The study design should be driven by your research question, not convenience. Cross-sectional studies cannot establish causation. Retrospective studies have inherent biases. Consult a biostatistician early to ensure your design matches your objectives.
Mistake 4: Ignoring Sample Size Calculation
Starting data collection without a proper sample size calculation is a recipe for an underpowered study. Calculate your sample size a priori using tools like G*Power or OpenEpi, and add 10-20% for expected dropouts.
Mistake 5: Poor Data Management
Using Excel without proper variable coding, not backing up data, and entering data without validation rules leads to errors that are expensive to fix later. Use proper data management tools like REDCap or KoboToolbox from the start.
Mistake 6: Incorrect Statistical Analysis
Using parametric tests on non-normal data, ignoring assumptions, or running inappropriate tests weakens your results. Common errors include using independent t-tests when data are paired, not checking normality before choosing a test, and running multiple comparisons without correction.
Mistake 7: Writing in Passive Voice Excessively
While some academic traditions prefer passive voice, excessive use makes writing dull and hard to follow. Use active voice where appropriate: "We collected data from 200 participants" is clearer than "Data were collected from 200 participants."
Mistake 8: Plagiarism — Intentional or Accidental
Paraphrasing without citation is still plagiarism. Use reference management tools (Mendeley, Zotero, EndNote) to track every source. Run your draft through Turnitin or iThenticate before submission. Aim for similarity below 15% (excluding bibliography and quotations).
Mistake 9: Ignoring University Formatting Guidelines
Each university has specific formatting requirements — margins, font size, citation style, chapter structure. Not following these leads to rejection at the submission stage. Get the formatting guide early and set up your document template before writing.
Mistake 10: Working in Isolation
Not seeking feedback until the final draft is a critical mistake. Schedule regular meetings with your guide, join peer writing groups, and seek external input on methodology and analysis. At Utkarsh Research Network, we provide chapter-wise thesis guidance to help you stay on track from start to finish.
