Use real data and precise language to work confidently with analysing data. In this lesson, focus on data work begins with a clear question and ends with a supported conclusion.
Data work begins with a clear question and ends with a supported conclusion. Choose an honest representation, calculate relevant summaries and quote evidence rather than relying on vague impressions. For analysing data, the final written answer should make that exact relationship visible rather than hiding it inside an unexplained result.
Analysing data: Data work begins with a clear question and ends with a supported conclusion. Trace every quoted value back to the table or chart and ask whether the conclusion answers the original question. Keep the analysing data representation visible until the final line.
Build a frequency table from raw values and switch between chart and summary views before writing a conclusion. Use the model to explain one change you notice while working on analysing data.
Trace every quoted value back to the table or chart and ask whether the conclusion answers the original question. Write that check beside the final analysing data answer.
Given information: Analysing data — Choose the reliable next step for a sample of 20 pupils. Method choice: Identify the values, frequencies or categories that answer the question. Quote the numbers being compared and link the conclusion to the context. Calculation or reasoning: The context is a sample of 20 pupils. A reliable statistical decision is to the sample suggests a pattern because the conclusion must be supported by the data and its collection method. Final answer: the sample suggests a pattern. Check: Quote the numbers being compared and link the conclusion to the context.

Worked examples
Understand the idea with small numbers, one representation and one clear step.
Use the standard Year 8 method with mixed examples and normal wording.
Handle multi-step or less familiar questions and explain choices.
Solve a worded question, show reasoning, check accuracy and write a final sentence.
Given information: Analysing data — Choose the reliable next step for a sample of 20 pupils. Method choice: use the analysing data method and show each step with the stated values. Calculation or reasoning: The context is a sample of 20 pupils. A reliable statistical decision is to the sample suggests a pattern because the conclusion must be supported by the data and its collection method. Final answer: the sample suggests a pattern. Check: substitute or compare with the original information to confirm the result fits the question.
Given information: Analysing data — State the strongest conclusion for a questionnaire. Method choice: use the analysing data method and show each step with the stated values. Calculation or reasoning: The context is a questionnaire. A reliable statistical decision is to use a neutral question because the conclusion must be supported by the data and its collection method. Final answer: use a neutral question. Check: substitute or compare with the original information to confirm the result fits the question.
Check: Check the analysing data result against the original information.
Given information: Analysing data — Select the method that avoids a misleading claim for a line of best fit. Method choice: use the analysing data method and show each step with the stated values. Calculation or reasoning: The context is a line of best fit. A reliable statistical decision is to treat an estimate as approximate because the conclusion must be supported by the data and its collection method. Final answer: treat an estimate as approximate. Check: substitute or compare with the original information to confirm the result fits the question.
Try explaining why each step works before checking the answer.
Given information: Analysing data — Complete the analyst's advice for a school survey. Method choice: use the analysing data method and show each step with the stated values. Calculation or reasoning: The context is a school survey. A reliable statistical decision is to check whether the sample is representative because the conclusion must be supported by the data and its collection method. Final answer: check whether the sample is representative. Check: substitute or compare with the original information to confirm the result fits the question.
Trace every quoted value back to the table or chart and ask whether the conclusion answers the original question. Write that check beside the final analysing data answer.
Create a analysing data problem with a tempting incorrect answer. Solve it, apply the check, and explain exactly where the incorrect method breaks down.
