Writing a dissertation is a formidable task that demands rigorous research, a clear structure, and precise language. However, even the most diligent students often stumble over common English mistakes that can undermine the quality of their work. These errors range from grammar and syntax issues to improper formatting and citation. This blog aims to highlight some of the most common mistakes made in dissertations and provide tips on how to avoid them, ensuring your dissertation is polished, professional, and impactful.
Grammar and Syntax Errors
Subject-Verb Agreement
One of the most frequent mistakes in dissertations is subject-verb agreement. This error occurs when the verb does not match the subject in number (singular or plural).
Incorrect: The results of the experiment shows significant differences.
Correct: The results of the experiment show significant differences.
Tip: Always ensure that your verbs agree with the subjects. If the subject is singular, use a singular verb. If the subject is plural, use a plural verb.
Misplaced Modifiers
Modifiers must be placed next to the words they are meant to describe. Misplaced modifiers can lead to confusing or humorous sentences.
Incorrect: The researcher found the data frequently using the wrong methodology.
Correct: The researcher frequently found the data using the wrong methodology.
Tip: Place modifiers as close as possible to the words they modify to maintain clarity.
Pronoun-Antecedent Agreement
Pronouns must agree in number and gender with the nouns they replace.
Incorrect: Each participant must submit their form by the end of the day.
Correct: Each participant must submit his or her form by the end of the day.
Tip: When in doubt, rephrase the sentence to avoid awkward pronoun constructions, or use singular “they” if appropriate.
Comma Splices and Run-On Sentences
Comma splices occur when two independent clauses are joined by a comma without a coordinating conjunction.
Incorrect: The study was comprehensive, it covered all relevant topics.
Correct: The study was comprehensive; it covered all relevant topics.
Tip: Use a semicolon, conjunction, or break into two sentences to fix comma splices.
Stylistic and Structural Issues
Passive Voice
While passive voice is not grammatically incorrect, it can make your writing less direct and harder to read.
Passive: The experiment was conducted by the researchers.
Active: The researchers conducted the experiment.
Tip: Use active voice where possible to make your writing clearer and more engaging.
Redundancy and Wordiness
Redundant phrases and unnecessary words can make your writing less effective.
Incorrect: Due to the fact that the results were surprising in nature, it can be concluded that the hypothesis was incorrect.
Correct: Because the results were surprising, the hypothesis was incorrect.
Tip: Be concise. Eliminate unnecessary words and phrases that do not add meaning.
Inconsistent Tense
Dissertations often switch between past and present tense, which can confuse the reader.
Incorrect: The researcher concludes that the data was significant.
Correct: The researcher concluded that the data was significant.
Tip: Maintain consistent tense throughout your dissertation. Typically, use past tense for methods and results, and present tense for discussing implications and conclusions.
Citation and Formatting Mistakes
Improper Citation
Failing to cite sources correctly can lead to accusations of plagiarism.
Incorrect: Smith (2020) states that “climate change is accelerating” (p. 45).
Correct: Smith (2020) states, “Climate change is accelerating” (p. 45).
Tip: Familiarize yourself with the citation style required by your institution (APA, MLA, Chicago, etc.) and apply it consistently.
Incorrect Use of Footnotes and Endnotes
Footnotes and endnotes are used to provide additional information or cite sources. Incorrect usage can distract or confuse the reader.
Incorrect: Smith^1 argues that the policy is ineffective.^1
Correct: Smith argues that the policy is ineffective.^1
Tip: Use footnotes and endnotes sparingly and ensure they follow the correct format.
Formatting Errors
Formatting errors can make your dissertation look unprofessional.
Incorrect:
– Inconsistent font sizes and styles.
– Misaligned headings and subheadings.

Tip: Follow the formatting guidelines provided by your institution meticulously. Use templates if available.
Commonly Confused Words and Phrases
Affect vs. Effect
– Affect is a verb meaning to influence.
– Effect is a noun meaning the result of a change.
Incorrect: The new policy had a significant affect on the economy.
Correct: The new policy had a significant effect on the economy.
Tip: Remember that “affect” is usually a verb and “effect” is usually a noun.
Its vs. It’s
– Its is a possessive pronoun.
– It’s is a contraction for “it is” or “it has.”
Incorrect: Its going to rain today.
Correct: It’s going to rain today.
Tip: If you can replace “it’s” with “it is” or “it has,” use the contraction.
Then vs. Than
– Then is used to indicate time or sequence.
– Than is used for comparisons.
Incorrect: She is taller then her brother.
Correct: She is taller than her brother.
Tip: Use “than” for comparisons and “then” for time or sequence.
Research and Content Mistakes
Lack of Clear Research Question or Hypothesis
A clear research question or hypothesis guides your dissertation and gives it purpose.
Incorrect: The study looks at various aspects of climate change.
Correct: The study investigates how climate change affects coastal erosion rates in the Pacific Northwest.
Tip: Formulate a specific, focused research question or hypothesis at the beginning of your study.
Insufficient Literature Review
A strong literature review contextualizes your research within existing studies and identifies gaps.
Incorrect: The literature review is brief and does not cover all relevant studies.
Correct: The literature review comprehensively covers recent studies, highlighting gaps and areas for further research.
Tip: Conduct a thorough review of existing literature and discuss its relevance to your research.
Weak Methodology
Your methodology section should clearly describe how your research was conducted and justify your chosen methods.

Correct: The methodology section details the research design, data collection, and analysis methods, and explains why these methods were chosen.
Tip: Provide detailed descriptions of your research methods and justify their use.
Logical and Analytical Errors
Unsupported Conclusions
Conclusions must be supported by data and logical reasoning.

Correct: The majority of students in the study preferred online learning, indicating a trend that warrants further research.
Tip: Be specific and cautious when generalizing your findings.
Lack of Critical Analysis
A dissertation should not merely describe existing research but critically analyze and synthesize it.
Incorrect: The literature review only summarizes existing studies without critique.
Correct: The literature review critically examines existing studies, identifying strengths, weaknesses, and gaps.
Tip: Engage critically with the literature, highlighting its implications for your research.
Presentation and Style Issues
Poor Abstract
The abstract is a concise summary of your dissertation. A poorly written abstract can fail to capture the essence of your research.
Incorrect: This dissertation is about climate change.
Correct: This dissertation investigates the impact of climate change on coastal erosion rates in the Pacific Northwest, employing quantitative analysis of historical data and predictive modeling.
Tip: Write a clear, concise abstract that summarizes the key points of your research, including the research question, methods, results, and conclusions.
Ineffective Titles and Headings
Titles and headings guide the reader through your dissertation. Ineffective titles can confuse or mislead the reader.
Incorrect: Chapter 1: Introduction
Correct: Chapter 1: Introduction to the Impact of Climate Change on Coastal Erosion
Tip: Use descriptive titles and headings that accurately reflect the content of each section.
Inconsistent Terminology
Using inconsistent terminology can confuse the reader and undermine the coherence of your dissertation.
