Using Data for Decision-Making is a Grade 7 Computer Science worksheet that teaches students how to interpret information, evaluate evidence, and justify choices with logical reasoning. Through realistic school-based examples, students explore how survey results, accurate records, and data comparisons can support recommendations without treating personal opinions or numerical patterns as proof.

Students investigate a practical question: how can a school or classroom choose the most suitable option when several alternatives are available? They examine survey totals, compare competing proposals, consider costs and other constraints, and distinguish a conclusion about what the evidence suggests from a decision about what to do next.

What Students Practise

• Interpreting tables and charts: Compare numerical results to identify which activities or proposals receive the most support.
• Checking data quality: Explain why accurate records, careful collection methods, and representative samples matter.
• Drawing evidence-based conclusions: Separate supported claims from guesses, unsupported opinions, and assumptions about cause and effect.
• Applying logical reasoning: Use survey results and cost information to recommend an option while considering additional factors that could affect the final choice.
• Explaining limitations: Recognise why a small survey or a chart showing a pattern may not provide enough evidence to support a broad claim.

Worksheet Activities

The worksheet moves from recognising key ideas to applying them in practical decision-making situations. Students complete a Data Detectives dialogue, a matching activity, a cloze passage, and a labelled diagram. A reading passage, Using Data for Decision-Making, provides context for questions about reliable information, interpreting results, evaluating alternatives, and explaining conclusions.

Students then respond to multiple-choice questions and true-or-false statements, write concise answers using evidence, and complete an extended-response task. In the final scenario, they recommend a technology improvement for a school using student survey results and estimated costs. They must support their recommendation with the available information and identify an additional factor the school should consider.

Included in This Resource

• ✔️ Grade 7 Computer Science worksheet on Data and Information
• ✔️ Dialogue, matching, cloze passage, and labelled diagram activities

Classroom Uses

Use this data analysis worksheet during a Computer Science lesson on Data and Information, as independent practice after introducing evidence-based reasoning, or as a review activity before students apply data to a classroom or school decision. The reading and structured questions give students opportunities to work with the same core ideas in different ways, while the extended response requires them to connect numerical evidence with practical constraints.

The separate Teacher Guide supports lesson preparation and classroom discussion by identifying learning objectives, teaching suggestions, questions for deeper thinking, and common mistakes to address. The resource uses a general framework rather than claiming alignment with a specific curriculum standard.

For teachers who want Grade 7 students to move beyond reading numbers and begin explaining what those numbers justify, this resource provides focused practice in interpreting data, evaluating evidence, and making reasoned recommendations.
