Common Dissertation Methodology Mistakes
A mistake-correction guide for unclear problems, weak questions, method mismatch, sampling issues, vague analysis, ethics gaps, limitations, and overclaiming.
Use this guide when your methodology chapter has supervisor comments, unclear method logic, weak sampling, vague analysis, thin ethics, or claims that go beyond the evidence.
Overview
How to use this guide
Start with the overview, complete the checklist rows honestly, then use the gap and readiness tables to decide what needs review before submission or consultation.

Checklist
Main checklist and template content
Work through each section as a review row. Blank boxes are intentional so you can print the guide and mark what is complete.
Unclear research problem
If the problem is unclear, the method cannot be justified.
The problem statement is specific and researchable.
The chapter does not rely on broad social or industry claims without narrowing.
The problem explains what evidence is needed.
The problem is consistent across proposal, introduction, and methodology.
The method responds to the problem directly.
Weak research questions
Weak questions create weak methods and vague findings.
Questions are answerable with available data.
Questions are not topic headings disguised as questions.
Questions match qualitative, quantitative, mixed, or design methods.
Sub-questions do not duplicate each other.
Questions can be mapped to analysis steps.
Method does not match objectives
Method mismatch is one of the most serious methodology problems.
Each objective has a method and evidence source.
The method can produce the kind of answer the objective requires.
The chapter avoids using convenience as the only method reason.
Alternative methods are considered where useful.
The method is feasible and academically acceptable.
Poor sampling logic
Sampling should be justified by the research aim, not simply by who is easy to reach.
Target population and accessible sample are separated.
Inclusion and exclusion criteria are clear.
Sampling strategy is named and justified.
Recruitment route is realistic and ethical.
Sampling limitations are acknowledged.
Unrealistic sample size
Sample size should fit the method, deadline, access, and analysis plan.
The proposed size is achievable within the data collection window.
Quantitative work considers response rate and statistical needs.
Qualitative work considers depth, saturation, information power, or case richness.
The chapter has a plan if recruitment falls short.
Claims do not exceed the sample's ability to support them.
Vague data collection plan
A vague data collection plan makes the study hard to approve, replicate, or defend.
The chapter explains what data will be collected and from where.
Steps are described in practical order.
Instruments, platforms, permissions, and timelines are identified.
Consent and data storage are included.
The plan has risk and backup options.
Unsupported analysis method
Analysis should fit the data type and research questions.
The analysis method is named correctly.
The method is justified using data type, design, and objectives.
Software or manual procedures are described.
Assumptions, coding rules, or statistical requirements are considered.
The chapter avoids selecting analysis because it sounds advanced.
Missing validity/reliability discussion
Quality criteria should match the methodology.
Quantitative studies address validity and reliability where relevant.
Qualitative studies address credibility, transferability, dependability, and confirmability where appropriate.
Pilot testing, expert review, triangulation, or audit trail are included only if suitable.
Threats to quality are explained honestly.
Quality checks are connected to the actual study.
Weak ethics section
Ethics sections fail when they are generic or disconnected from actual data collection.
Consent, withdrawal, privacy, anonymity, and data storage are described.
Ethics approval or exemption route is stated.
Sensitive participants, topics, or datasets receive extra care.
The chapter avoids invented approval claims.
AI tools, confidential data, and third-party platforms are considered if used.
Ignored limitations
Ignoring limitations makes findings less credible, not stronger.
Sampling, access, measurement, timing, researcher role, and data quality limits are acknowledged.
Limitations are linked to interpretation of findings.
Delimitations explain deliberate scope boundaries.
The chapter explains how limitations are managed.
Conclusions stay within limitations.
Overclaiming findings
Methodology should protect the dissertation from claims the evidence cannot support.
The study does not claim causality without a causal design.
Small or context-specific samples are not generalized too broadly.
Qualitative findings are presented as interpreted evidence, not universal truth.
Technical results are not overstated beyond test conditions.
The discussion uses cautious and accurate wording.
Poor methodology chapter structure
A strong chapter guides the reader through decisions in a logical order.
The chapter moves from research problem to design, approach, method, sample, data collection, analysis, quality, ethics, and limitations.
Headings match university expectations.
Definitions do not replace study-specific justification.
Tables or matrices are used to show alignment where useful.
The chapter is written in a tense appropriate to the project stage.
Mistake correction checklist
Use this correction checklist after identifying methodology weaknesses.
Rewrite the research problem and questions before revising methods.
Create an objective-question-method-data-analysis alignment matrix.
Strengthen sampling, data collection, analysis, ethics, and limitation sections.
Ask your supervisor to confirm major method changes before collecting data.
Keep a revision record for viva and supervisor discussions.
Gap assessment
Methodology risk assessment
Use this table to move from general concern to a specific action before requesting review or making revisions.
| Review Area | Status | Gap Found | Action Needed |
|---|---|---|---|
| Alignment risk | High | Research questions, objectives, method, and analysis may not connect. | Build an alignment matrix and revise mismatched objectives or methods. |
| Sampling risk | Medium to high | Sample logic, access, or size may be unrealistic. | Define population, criteria, recruitment, sample size, and backup plan. |
| Analysis risk | High | Analysis method may be unsupported or incompatible with data. | Confirm data type, assumptions, software, coding, tests, or model choice. |
| Integrity risk | Must address | Ethics, limitations, or overclaiming may weaken credibility. | Add practical ethics procedures and revise claims to match evidence. |
Readiness score
Methodology risk score
Score honestly. A lower score is useful when it tells you where to focus before supervisor, reviewer, or submission review.
| Category | Score | Notes |
|---|---|---|
| Problem clarity | /10 | Low scores mean the methodology has no stable foundation. |
| Question-method fit | /10 | Low scores mean objectives may not be answerable. |
| Sampling and data plan | /10 | Low scores mean collection may fail or claims may be weak. |
| Analysis support | /10 | Low scores mean findings may be difficult to defend. |
| Ethics and limitations | /10 | Low scores mean the chapter may create integrity or defense risks. |
