Planning a statistical investigation
Plan and conduct a statistical investigation by posing a question or identifying a problem, collecting relevant data, choosing appropriate displays, interpreting the data and communicating findings in context
Lesson
Set out your lesson
“Planning a statistical investigation means practising the idea at the table with counters or paper models and one clear check. We will demo once, then your child tries.”
Bring to the table
- Tally sheet or simple bar sketch
- A short set of category counts
Extra for the adult
Worked example. Cats 4, dogs 2 — cats have more. The tally and comparison are the proof.
Optional challenge. For Planning a statistical investigation, add one harder example after success.
What to notice. Keep one parent note: examples tried; results; support used. This session samples Planning a statistical investigation, not mastery.

1 approach
Planning a statistical investigation means practising the idea at the table with counters or paper models and one clear check. We will demo once, then your child tries.
Materials: Tally sheet or simple bar sketch; A short set of category counts. Adult tallies one category and sketches a bar. Child tallies three categories and answers one comparison question. Done: three tallies plus one correct comparison. Stop after the fresh check; keep optional challenge for another day.

Public Illustrative Mathematics task page. The .html address responds HTTP 308 to this URL. An anonymous GET of this URL on 2026-11-12 returned HTTP 200 with no login or payment prompt. Where a teacher solution is present, it is on the same page as the student task; this check did not find a separate locked student view. An adult can use the student view section and should not read a solution aloud. Advertising was not observed in the fetched HTML text; that is not a browser, device, or ad-free guarantee. This is a paper or discussion task, not an automatically marked interactive game. Opening the link does not save practice or assess mastery. Diagrams on the page use missing or filename-only alt text, so they are not an accessible image equivalent. Accessibility still depends on an adult describing the picture.

Check understanding
- Pose an investigation question such as 'Do Year 5 students sleep less on school nights?', refining a vague question (e.g. 'Do kids like sport?') into one that data can answer, and plan how to collect the data
- Choose and justify a display (column graph, dot plot or table) for the collected data
- Write a short report that answers the question and states one limitation of the data
“Could your child come up with their own question — like whether kids sleep less on school nights — plan how to collect the data, and report what they found?”
