Conducting and Communicating Statistical Investigations worksheet

Use this printable homework sheet for written working, application and reflection alongside the online learning activities.

Open practice

Eight independent written and practical tasks

Keep source records, digital displays and written explanations. An adult checks practical evidence; unavailable source access remains pending.

  1. Conduct an original favourite-reading-format survey with at least five willing people. Record one anonymous response each in a spreadsheet and check frequencies.

  2. Graph that survey digitally and present two numerical findings and a limitation to another person. Record one question they ask and your answer.

  3. Observe ten trials of a safe paper-plane landing activity, recording before or at/beyond a line using one consistent rule. Enter counts digitally, graph and report the observed result.

  4. Retrieve comparable monthly rainfall data for two places from actual official online sources with an adult. Record source details, dates and units, make a digital display and explain a difference.

  5. Design a table for investigating cereal sugar and shelf height. Define an eye-level band, sugar per 100 g comparison and duplicate-product counting rule. Explain each choice.

  6. Using at least five actual cereal positions documented with permission or adult-provided photographs, collect shelf category and sugar per 100 g, represent the records digitally and communicate a bounded finding.

  7. A digital survey table has Sport 9, Art 5, Music 4. The Art count of 5 includes one accidentally duplicated Art response. Correct the table, graph it and report the total and largest category.

  8. Compare two actual online records you considered for your investigation. Record differences in place, dates, variables or units and explain whether they can be compared directly.

Answers and adult review guidance

  1. Actual responses vary; preserve all genuine responses and total 5 or more. Inspect neutral question, group, actual raw records and digital table.

  2. Actual values determine comparisons; limit findings to respondents. Inspect matching graph and evidence of communication.

  3. Two counts total 10; report the setup and limited trial set. Inspect real observations, digital output and bounded conclusion.

  4. Values vary; use matching periods and rainfall units, distinguish missing from 0. Require source records and exact faithful display; pending if inaccessible.

  5. Consistent definitions make the observation answerable and comparable; product versus shelf-position counting must be stated. Inspect actual table and plan, not a multiple-choice selection.

  6. Findings depend on actual data; one shop/selection does not prove universal placement or intention. Inspect evidence, comparable units, digital display and limitation; pending without real records.

  7. Sport 9, Art 4, Music 4; total 17; Sport is largest. Inspect corrected display and duplicate justification.

  8. Accept a justified valid comparison or a documented mismatch; do not force incompatible sources into a claim. Inspect two source records and reasoned compatibility decision.
