ENGLISH · LESSON 14 OF 20
Use evidence without overstating it
What this lesson helps you do
Compare sources according to what each can establish and state the limits of a conclusion.
Before this lesson
This lesson builds on:
The explanation
A claim needs evidence relevant to that claim. Preferences can support a statement about what respondents like; they cannot by themselves establish an effect on performance. A measured association can be useful, but alternative explanations may remain. Name the population, conditions and outcome before deciding how strong a conclusion should be.
When several sources discuss a topic, organise the writing around the issue rather than giving one unrelated paragraph per source. Explain where the sources agree, what each contributes and why their limits matter. Disagreement can arise because they measured different outcomes or used different participants.
The two records below are fictional teaching data. In a real assignment, use traceable sources, inspect the relevant sections and follow the required citation style. A plausible title, quotation or publication date must never be invented to make a paragraph appear researched.
Language pattern
- Pattern
- Claim + relevant evidence + explanation of the link + limitation.
- What it does
- Show why the evidence bears on the claim.
- Limits
- Combining weak evidence does not automatically produce a strong conclusion.
A first worked example
Combine two kinds of information
Situation. Fictional training record A: 12 of 18 volunteers preferred a quiet study room. Record B: observers counted 24 occupied seats in that room and 20 in a discussion area on one Tuesday at 14:00.
The training records suggest interest in the quiet room, but they describe different outcomes. Record A reports a preference among a small volunteer group. Record B records occupancy at one time. Together they can inform a decision to investigate demand further; they do not demonstrate that the room improves grades or that demand is always higher.
Why it works
- The paragraph distinguishes preference from occupancy.
- The sample and time limits are preserved.
- The proposed next decision is proportionate to the evidence.
What it shows: A useful synthesis can explain what remains unknown.
A second worked example
Avoid a causal leap
Situation. An invented observation finds that students who attend a study group also tend to submit more assignments.
Study-group attendance was associated with more frequent assignment submission in this observation. The result does not establish whether attendance caused the difference, because other factors may have influenced both.
Why it works
- Associated reports a relationship without asserting cause.
- The outcome is assignment submission, not grades.
- The limitation gives a reason for cautious interpretation.
What it shows: The wording preserves useful information while acknowledging uncertainty.
Common mistakes
Draft (not correct): Both sources mention the room, so they prove the same thing.
Revision: Identify what each source actually measured.
A shared topic does not imply identical evidence.
Draft (not correct): A source is credible because its title sounds academic.
Revision: Check the source, method and relevance to the specific claim.
Presentation alone does not establish reliability.
Keep in mind
- Match evidence to the exact claim.
- Keep methods and outcomes distinct.
- Use real, traceable references.
Foundation lesson; not an official syllabus, accredited CEFR placement, or score prediction.
Next: Revise meaning before polishing words. Improve a paragraph in a sequence that protects meaning, organisation and accuracy.
