'_____ study is limited to single-language repositories written in Python.' What does this sentence accomplish in a limitations section?
'This study is limited to [scope]' is the standard phrase for defining the boundaries of your research. It is not an apology — it is precise scoping. All research has scope limits; declaring them explicitly shows methodological honesty and prevents readers from over-generalising your findings to contexts you did not study.

'_____ work should investigate whether these results generalise to multilingual codebases.' What does this phrase signal?
'Future work should' is the conventional phrase for directing the research community toward open problems your paper has not solved. It signals intellectual honesty (you know your scope) and contributes to the field by identifying research gaps. Other forms: 'Future research could explore', 'Subsequent studies might address', 'A promising direction for future work is'.

'_____ to validity include the reliance on a single proprietary dataset.' What category of research limitation does this phrase introduce?
'Threats to validity' is a formal term from research methodology, distinguishing types of validity at risk: internal validity (did the study correctly isolate the effect?), external validity (do results generalise?), construct validity (does the measure match the concept?), and conclusion validity (are statistical conclusions sound?). Using 'threats to validity' signals familiarity with research methodology discourse.

'The _____ of these findings is restricted to enterprise software teams with over 100 developers.' What word correctly describes the reach or applicability of results?
'Scope of findings' is the standard phrase for describing how broadly the results apply. 'The scope is restricted to X' is more formal and precise than 'limited to' — it implies a deliberate boundary rather than a failure. In limitations sections you might write: 'The scope of this study is restricted to synchronous communication tools; asynchronous tools were excluded by design.'

'We acknowledge that the lack of a control group represents a _____ to the internal validity of this study.' Which word correctly fills the blank?
'Threat to validity' is the technically correct phrase — not 'problem' or 'mistake', which imply avoidable errors. A threat is a methodological constraint that may affect the interpretation of results. Internal validity threats include selection bias, maturation, instrumentation changes, and lack of randomisation. Naming the threat and explaining its likely impact shows methodological sophistication.

Code Review Comment: 'This analysis is limited by the small sample size of just five production servers. We should consider running a larger-scale test with more diverse configurations.' What does this comment primarily highlight regarding the research limitations?
This comment focuses on the sample size being too small to draw broad conclusions. The core limitation identified is that the results aren't likely generalizable because they're based on a restricted set of data. Option A is incorrect as it suggests a methodological flaw beyond just sample size; options C and D misinterpret statistical significance or suggest further investigation without acknowledging the underlying problem.

Slack Message: 'Just finished analyzing the log data from our latest deployment. The limitations are pretty clear – we only tracked errors related to authentication failures; other types of performance issues weren't captured.' What does this message suggest about the research?
The message explicitly states that the analysis only tracked *authentication failures*, indicating a narrowed scope. This represents a limitation because it excludes other potential performance issues. Option A is incorrect as it contradicts the statement; option C implies automation without addressing the scope and option D is an unsupported conclusion. Therefore, the core limitation is a biased focus.

PR Description: 'The API endpoint performance was evaluated using synthetic traffic generated by our internal load testing tool. The limitations of this approach are that it doesn't fully replicate real user behavior and may not expose edge cases.' What type of research limitation does this description primarily address?
The phrase 'doesn't fully replicate real user behavior and may not expose edge cases' directly relates to external validity. This signifies a limitation in the generalizability of the findings because the testing environment differs from actual usage scenarios. Options A, C, and D represent different types of errors but don't capture this specific concern about replicating realistic conditions.

Standup Update: 'We've completed the initial profiling of the new database schema. The main limitation is that we only used MySQL for this evaluation; performance might differ significantly on other databases like PostgreSQL.' What term best describes the scope restriction?
The statement explicitly mentions 'only used MySQL,' indicating a restriction based on the data source. This limits the applicability of the findings to systems utilizing MySQL. Options A and B are not directly relevant; option D is the most accurate description of this constraint.

Code Review Comment: 'The results of this study should be interpreted cautiously. The team was comprised solely of front-end developers with no back-end experience, which may influence the interpretation of the data.' What does this comment indicate about the limitations?
The comment highlights the potential for researcher bias due to the team's lack of back-end experience. This suggests that their understanding and interpretation of the data could be influenced by this specific limitation, potentially skewing conclusions. Options A, C, and D are irrelevant to the core issue raised here.
What will I practice in "Research Limitations Section Vocabulary"?
This is a Research English exercise set. It walks through 10 scenario-based multiple-choice questions built around real usage of research english terminology that IT professionals encounter on the job.
Is this exercise free to use?
Yes. Every exercise on CoderSlingo, including this one, is free to complete with no account, sign-up, or paywall.
How many questions are in this exercise?
This set contains 10 questions. Each one shows immediate feedback and a detailed explanation after you answer, so you learn the correct usage right away rather than waiting for a final score.
Do I need prior experience to complete this exercise?
No prior experience is required. Each question includes a full explanation covering the reasoning behind the correct answer, so the exercise itself teaches the research english vocabulary as you go.
Can I retry the exercise if I get questions wrong?
Yes — use the "Try again" button on the results screen to reset your answers and go through all the questions again. There is no limit on attempts.
Is my progress saved?
Your answers and score for the current session are tracked in the browser as you go. No account or login is needed, and there is nothing to install.
