Notes on Paragraph Structure: Topic Sentences, Evidence, Analysis, and Concluding Sentences

Topic Sentence

• Purpose: states the main idea of the paragraph and keeps the paragraph focused on a single idea.
• Characteristic: should be very direct and clear, not poetic or sophisticated in style.
• One-word/main idea approach: identify a single word that represents the paragraph’s focus (e.g., Polite, Convenience, Efficiency).
• Connection to thesis: every topic sentence should clearly connect back to the overall thesis of the essay.
• Writing tip: a clear topic sentence helps the reader know what the paragraph is about and helps you stay aligned with the thesis.
• Example structure:
  • Topic sentence example: "Chick-fil-A employees are always polite."
  • Focus word: Polite (the main idea of the paragraph).
  • Why it matters: Politeness connects back to customer service, because how employees interact affects the overall perception of service quality.
• Style guidance: topic sentences should be straightforward and not attempt to be artistic or Shakespearean.
• Quick takeaway: if you get stuck, identify the main idea of the paragraph in one word, then craft a sentence that states that idea clearly.
• Practice note: in discussion, there was debate about whether to use direct or more nuanced language; the consensus emphasized directness for topic sentences.

Evidence

• Definition: evidence is the body of information used to support your main idea (the topic sentence).
• Types of evidence (three common methods):
  • Quoting: directly quoting a source, e.g., "Nick says, quote…" (quotation).
  • Summarizing: restating the source’s ideas in a condensed form.
  • Paraphrasing: rewording a source’s ideas in your own words.
• Different kinds of evidence and their purposes depend on the assignment and discipline.
• Empirical evidence (data-driven):
  • Definition: evidence that can be measured numerically and reproduced, i.e., statistics and hard data.
  • Example: numerical sales figures, percentages, and other hard numbers.
  • Notation example: $21{,}580{,}000{,}000.00$ (sales in 2023) and related $14.7\%$ increases and dollar amounts like $18{,}810{,}000{,}000.00$; $43\%$ over 2021; $15{,}000{,}000{,}000.00$ for comparison.
• Anecdotal evidence (personal experiences):
  • Definition: experiences, observations, and testimonies that are not easily measurable or reproducible.
  • Examples: customer reviews, personal narratives, jury testimonials.
  • Limitation: although valid, they are not universally measurable or repeatable.
• Personal experiences and primary vs secondary sources:
  • Personal experiences: valid if truly relevant to the topic (e.g., involvement in a dance team when discussing dance topics).
  • Primary sources: original materials (e.g., the play Romeo and Juliet, the Declaration of Independence).
  • Secondary sources: sources about the originals (e.g., a scholarly article about Romeo and Juliet, a documentary about the Declaration).
• Visuals in evidence:
  • Visuals can function as evidence when they meaningfully support the main idea (graphs, charts, tables, infographics).
  • Discipline context matters (e.g., in medicine, empirical data may be prioritized).
• Real-world example discussed:
  • Chick-fil-A data illustrate empirical evidence (numbers and percentages) and contrasting anecdotal review quotes.
  • Example comparison: a review saying "Fast, friendly, and ready to serve" provides anecdotal insight but cannot be mathematically measured; in contrast, the sales figures provide empirical data.
• Practical tips about evidence:
  • Choose evidence appropriate to the field and assignment.
  • Balance is key: numbers and data should be paired with interpretation (analysis).

Analysis

• Definition: analysis means examining the evidence and explaining its meaning, significance, and relation to the thesis.
• Three core functions of analysis:
  • Explain what the evidence means to you (interpretation).
  • Explain the significance of the evidence (why it matters; what the numbers imply).
  • Connect the evidence back to the thesis (show how it supports the main argument).
• Why analysis is often challenging:
  • People assume everyone will interpret numbers the same way, which is not always true.
  • Writing requires explicit analysis to guide the reader to the intended interpretation.
• Guidelines for effective analysis:
  • Always explain what the evidence means to you, even if you think the meaning is obvious.
  • Always explain the significance of the evidence (e.g., why a 14.7% increase matters in context).
  • Always connect the evidence back to the thesis so the paragraph contributes to the overall argument.
• Balance rule for analysis and evidence:
  • A healthy paper should have roughly $70\%-75\%$ of the content as your own writing (topic sentences, analysis, transitions, conclusion, etc.).
  • The remaining $25\%-30\%$ can come from sources.
  • For every line of evidence, you should follow with a line of analysis (the evidence/analysis ratio).
  • If a quotation is multiple sentences long, the following sentences should be analysis to maintain balance.
• Paragraph-level template for efficient drafting:
  • Evidence-first approach helps you know what you are arguing and makes the rest easier to craft.
  • Typical structure (in practice): Evidence → Topic sentence → Analysis → Concluding sentence, with transitions ensuring flow.
• Important caveat:
  • If you write a paragraph and someone else cannot reorder it into a coherent sequence, something is off with the organization or the logic.

Concluding Sentence

• Purpose: wraps up the paragraph and shows takeaway.
• Writing guidance: should be written last.
• Function: provides a closing thought or a bridge to the next paragraph (e.g., a therefore moment).

Four-part Paragraph Template (and Practical Ordering Rules)

• Four required parts of a body paragraph:
  • Topic sentence: states the main idea of the paragraph.
  • Evidence: provides supporting details (2–3 examples is a safe range).
  • Analysis: explains what the evidence means, its significance, and connects to the thesis.
  • Concluding sentence: wraps up and reinforces the paragraph’s main point.
• Practical drafting order (recommended):
  • Always plug in the evidence first.
  • Then craft the topic sentence that matches the evidence.
  • Then add analysis to interpret the evidence.
  • Finally, write the concluding sentence last.
• Sandwich analogy:
  • Topic sentence and concluding sentence are the bread.
  • Evidence and analysis are the filling between the bread slices.
• How much evidence to include:
  • Two to three examples is a safe count for most body paragraphs.
  • One detailed example is possible but may require a longer analysis.
  • Three examples can become very long; consider splitting into two paragraphs.
• Quick exercise idea (order activity):
  • You are given five sentences (1–5) including topic sentence, evidence, analysis, and concluding sentence.
  • The task: order them into a coherent paragraph order (the instructor suggested a correct order of 3-2-1-5-4 in one example).
  • The key is to ensure the order makes sense with the flow: introduce main idea, present evidence, analyze, then conclude.

Topic Sentence and Evidence Practice (Demonstration Example)

• Prompt: Create a body paragraph with the topic sentence "Chick-fil-A employees are always polite" and supply evidence, analysis, and concluding sentence.
• Potential approach:
  • Topic sentence: Chick-fil-A employees are always polite.
  • Evidence: 1) Quote or paraphrase a positive customer review about politeness; 2) Empirical data about service-related metrics (e.g., satisfaction scores); 3) Anecdotal observation about consistent politeness across shifts.
  • Analysis: Explain how politeness influences perceived customer service quality and satisfaction scores; connect to thesis about overall service quality.
  • Concluding sentence: Therefore, politeness is a key driver of Chick-fil-A’s customer service reputation.

Evidence vs. Theory: Common Pitfalls and Clarifications

• Empirical vs Anecdotal: empirical is measurable data; anecdotal is personal experience.
• Primary vs Secondary sources: primary are originals; secondary are analyses about originals.
• Use of visuals: visuals can serve as evidence when appropriate to the discipline.
• Balance with imagination and reality: maintain a strong authorial voice (the student’s own analysis) while using evidence.
• Real-world relevance: the rules apply across disciplines, but emphasis may shift toward empirical data in sciences and formal statistics in business contexts.

Quick Reference Summary

• Topic sentence: one-word/main idea; direct; connects to thesis.
• Evidence: three forms (quoting, summarizing, paraphrasing); types (empirical, anecdotal); visuals as evidence.
• Analysis: three tasks (explain meaning, explain significance, connect to thesis); maintain balance with evidence; follow with a line of analysis for every line of evidence.
• Concluding sentence: written last; provides a takeaway.
• Paragraph building: evidence first helps structure the rest; 2–3 examples is a safe range; aim for 70–75% student writing, 25–30% sourced material.
• Ordering task takeaway: a coherent paragraph order is essential; practice with your notes to ensure you can reorder a jumbled paragraph into a logical flow.

Practical takeaway for exams

• When drafting a body paragraph, start with your evidence to anchor the paragraph, then derive the topic sentence, follow with analysis, and close with a concise concluding sentence.
• Always ensure your analysis ties back to your thesis and demonstrates your interpretation of the evidence.
• Be mindful of the balance between your own writing and source material to avoid over-reliance on quotes or paraphrase.
• Be prepared to explain the difference between empirical and anecdotal evidence, and when each is appropriate for a given assignment.
• Know the basic source types: primary vs secondary, and when visuals or data strengthen an argument.

Quick numeric references used in the example

• Sales in 2023: $21{,}580{,}000{,}000.00$
• 2022 increase: $14.7\%$
• 2022 sales reference: $18{,}810{,}000{,}000.00$
• 2021 increase over 2020: $43\%$
• 2021 value: $15{,}000{,}000{,}000.00$
• Balance rule: $70\%-75\%$ of the paper should be your own writing; $25\%-30\%$ can come from sources.
• For the order exercise: suggested order example is $3\,2\,1\,5\,4$.
• Example topic sentence main idea: Polite; direct connection to customer service.
