The parts of a lab report, and what each must do
Most lab reports follow the IMRaD pattern with a few additions. Knowing the job of each part makes it much easier to write and to check.
| Section | Its job | Common slip |
|---|---|---|
| Title and abstract | State what was tested and the main finding in a few lines | An abstract that reads like an introduction, with no result |
| Introduction | Give the background, theory and aim or hypothesis | Textbook summary with no link to the aim |
| Methods | Let a reader repeat the procedure | Copied as a numbered list from the lab manual |
| Results | Present data in figures and tables with brief text | Interpretation creeping in, or raw data dumps |
| Discussion | Interpret results, compare with theory, analyse error | Restating numbers without explaining them |
| Conclusion | Answer the aim directly | New information or vague claims |
| References and appendices | Cite sources; hold raw data and sample calculations | Missing in-text citations |
How we give feedback on your lab report
Your report is read by a tutor with lab experience in a related field: a chemist for titration reports, say, or an electrical engineer for circuit labs. They check that the science is sound as well as the writing, with units consistent, uncertainties propagated sensibly, graph axes labelled, and claims in the discussion actually supported by the numbers.
Comments go directly in the document. Where a pattern repeats, such as passive constructions that hide who did what, or figure captions that don't stand alone, the tutor flags one or two instances and explains the fix so you can apply it throughout. If your report uses a statistical test, we explain what the output means and how to report it; our guide to t-tests and how to report them covers one of the most common cases.
Discussing unexpected or messy results
Real experiments rarely produce textbook values, and markers know it. What earns credit is a thoughtful account of why. We coach you to separate random error from systematic error, estimate the size of each, and propose specific improvements instead of the vague "human error" line. A result that misses the expected value by twelve percent, honestly analysed, often makes a stronger discussion than a perfect match. Your conclusion then answers the original aim plainly, including any limits on that answer. For more on landing that final section, see our guide to writing a strong conclusion.
Format questions we answer every week
- Can I use "I" or "we"? Increasingly yes, especially in biology and psychology, but many chemistry and physics courses still prefer the passive voice. We check your department's guidance and keep you consistent.
- IEEE or APA? Engineering reports often use IEEE numbered citations; psychology uses APA 7. We make sure your in-text citations and reference list match the required style.
- Group reports. When several people write different sections, voice and formatting drift. We point out inconsistencies so the group can align them before submission.
- Length and time. A first-year report might take six to ten hours to write well, and a full engineering report far longer. Planning sections against the marking scheme saves much of that time.
Sending your report
Send your draft, the lab manual or handout, the marking rubric and your deadline via our quote form. Include your raw data file if the analysis is part of what you want checked. Feedback on a standard report usually takes one to three days. Because you collected the data and wrote the analysis, you can answer any question about it in a lab interview or practical exam, which is exactly why we work this way.
What you get
- A checklist of the required sections and format for your course or style guide
- Comments on your figures, tables, units and significant figures
- Feedback on your discussion and conclusion, including error analysis
- Explanations of any statistics in your report, such as t-tests or regression
- A short summary of the most important fixes before submission
What we don't do
- Generated data, results or report sections; the experiment and the write-up stay yours
- Filled-in pre-lab or post-lab worksheets, though we will explain the calculations and check your reasoning
- Overriding your instructor: department conventions vary, so your handout always takes priority over general advice
