📊 Part 4 — Statements About MY Chart

Use the chart you made in Session 5. Write statements using the sentence frames.

My survey question was:

👁️ Observation 1 — something you can see directly

Starter: "The data shows that…" or "_____ received the most/fewest…"

👁️ Observation 2 — a specific number from your chart

Starter: "_____ people chose…" or "The tallest bar is…"

🧠 Inference — what you think the data might mean

Starter: "This might mean that…" or "Based on the data, I think…"

🏁 Conclusion — answer to your original question

Starter: "Overall, the data suggests that…" or "If I had to answer my question, I would say…"

✍️ Part 5 — Think About It

What is the difference between an observation and an inference? Give an example of each.

Could two people look at the same chart and make different inferences? Why or why not?

What is one question your survey data CANNOT answer, even though you collected it?
