"Research paper" covers two quite different assignments. In the sciences and social sciences it often means an empirical paper reporting a study, structured as introduction, method, results and discussion (IMRaD).
In humanities and many general education courses it means an argument-based paper that answers a question using published sources. Both need a focused question, evidence and a clear structure, but they look different on the page.
This page gives you a fill-in outline for each type, an annotated model empirical paper in APA style and a model excerpt from an argument-based paper, all written by GradeEssays for illustration.
The study and data in the empirical model are fictional. For the full research and writing process, from narrowing a topic to final edits, see our research paper guide.
The standard research paper structure
An empirical research paper follows title page, abstract, introduction (ending with the research question or hypothesis), method, results, discussion and references. An argument-based research paper follows introduction with thesis, background, thematic body sections each supported by sources, counterarguments, conclusion and works cited. Use the outline for your type, then compare each section of your draft with the annotated models.

Annotated Model: Empirical Research Paper (APA Style)
Fictional study, written for illustration: "Part-Time Work Hours and Academic Self-Efficacy Among Undergraduate Students".
Introduction (excerpt). A growing proportion of undergraduates work part-time during term, often to cover living costs. Research has linked long working hours with lower grades and higher stress, but fewer studies have examined how work affects students' beliefs about their own academic ability, known as academic self-efficacy. Self-efficacy matters because it predicts persistence and effort independently of prior achievement [citations]. Moreover, some research suggests that moderate work may build time management skills that could support confidence [citations]. The present study therefore asked whether weekly work hours are associated with academic self-efficacy, and whether the relationship differs between students working fewer or more than 15 hours per week.
Method (excerpt). Participants were 214 undergraduates (aged 18 to 34) recruited through university email lists. They completed an online questionnaire including weekly paid work hours, a validated academic self-efficacy scale and demographic questions. Students who did not work formed the comparison group. Multiple regression was used to examine the association between work hours and self-efficacy, controlling for year of study and prior grades.
Results (excerpt). Students working more than 15 hours per week reported lower self-efficacy than non-working students, after controlling for year of study and prior grades. Students working 15 hours or fewer did not differ significantly from non-working students. Table 2 presents the regression coefficients.
Discussion (excerpt). The findings suggest that the relationship between work and academic confidence is not linear: moderate hours appear unrelated to self-efficacy, while longer hours are associated with lower confidence. This pattern is consistent with research identifying a threshold beyond which work begins to compete with study [citations]. Because the design was cross-sectional, it cannot show whether long hours reduce confidence or whether less confident students choose to work more. Longitudinal studies following students across a year would help clarify direction.
| Section | What makes it effective |
|---|---|
| Introduction | Moves from broad context to a specific gap, defines the key concept, and ends with a precise question that includes the threshold being tested. |
| Method | States sample, recruitment, measures and analysis, with enough detail for replication. Written in past tense. |
| Results | Reports findings plainly, points to the table, and does not interpret. |
| Discussion | Interprets the pattern, links to literature and names the most important limitation with its consequence. |
In a submitted paper, statistics would be reported in APA format (for example, β, t and p values) and bracketed citations would be real, verifiable sources. They are omitted here so the model does not present invented results or references as real.

Model Excerpt: Argument-Based Research Paper
Topic: "Should cities replace car parking with green space?" Written for illustration; bracketed notes show where sources would be cited.
Thesis paragraph. Cities facing rising temperatures and pressure on public space should convert a portion of on-street parking into green space, because doing so reduces local heat, supports local businesses more than critics expect, and returns public land to uses that benefit more residents. While the change raises legitimate concerns about access for disabled drivers and deliveries, these can be addressed through careful design rather than by keeping parking as the default use of street space.
Body paragraph. The economic objection, that removing parking harms local shops, is weaker than it first appears. Studies of shopping streets in several cities have found that retailers tend to overestimate how many of their customers arrive by car [citations]. Pedestrians and cyclists may spend less per visit but visit more often, so their total spending can match or exceed that of drivers [citations]. This does not mean every street suits conversion, but it does mean that the assumption that parking equals trade should be tested with local data before it blocks change.
| Feature | Why it works |
|---|---|
| Thesis with reasons and a concession | Previews the structure and shows awareness of complexity |
| Body paragraph tackles an objection directly | Turns a counterargument into support for the thesis |
| Sources described by finding | The point leads; citations support rather than drive the paragraph |
| Qualified claim | "This does not mean every street..." prevents overstatement |
Model Conclusion Paragraph
Conclusions are often the weakest part of a research paper because they simply repeat the introduction. This model conclusion for the fictional work-hours study shows a better pattern.
This study examined whether part-time work is associated with academic self-efficacy among undergraduates. The results suggest a threshold: working up to 15 hours per week was not associated with lower confidence, whereas longer hours were. These findings add to research on student employment by shifting attention from grades to students' beliefs about their own ability, which shape effort and persistence. For universities, the results point towards supporting students who work long hours, for example through flexible deadlines or timetabling, rather than discouraging work altogether. Future longitudinal research could establish whether long hours reduce self-efficacy over time or whether less confident students are more likely to take on extra work.

No new evidence appears, the claims stay within what the design allows, and the reader leaves with a clear answer and a reason it matters.
Research Questions: Weak to Strong
| Weak | Problem | Strong |
|---|---|---|
| "What is social media?" | Answerable by definition | "How does daily social media use relate to sleep quality among first-year students?" |
| "Is climate change bad?" | Too broad and settled | "How effective have urban tree-planting programs been at reducing summer street temperatures?" |
| "Why was the Roman Empire important?" | Vague, no argument | "How did grain supply policies affect political stability in Rome during the first century CE?" |

Frequently Asked Questions
A research paper relies on substantial outside research, or original data, to answer a question. An essay can be shorter and more interpretive, sometimes using fewer sources.
Undergraduate papers are often 1,500 to 5,000 words; graduate papers longer. Your assignment brief sets the length.
No. The study, data and argument excerpts were written by GradeEssays for illustration. Use them to study structure.
In APA 7, student papers need an abstract only if your instructor asks. Professional and journal papers usually require one.
It depends on level and length. A short undergraduate paper may need 5 to 10; longer or graduate papers usually need more.
Many writers draft it early but revise it last, once the body and conclusion are finished, so it matches what the paper argues.
APA 7 allows first person where appropriate ("we surveyed"). Humanities papers vary. Follow your instructor's guidance.
It is focused, answerable with available sources or data, and genuinely open, so that research is needed to answer it.
