Use real data and precise language to work confidently with quantitative 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 quantitative data, the final written answer should make that exact relationship visible rather than hiding it inside an unexplained result.
Quantitative 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 quantitative 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 quantitative 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 quantitative data answer.
Given information: Quantitative data — Which is quantitative data: favourite sport or height? 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: height is quantitative because it records a numerical measurement or count. Final answer: height. 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: Quantitative data — Which is quantitative data: favourite sport or height? Method choice: use the quantitative data method and show each step with the stated values. Calculation or reasoning: height is quantitative because it records a numerical measurement or count. Final answer: height. Check: substitute or compare with the original information to confirm the result fits the question.
Given information: Quantitative data — Explain the classification by choosing the quantitative variable: journey time or shirt colour. Method choice: use the quantitative data method and show each step with the stated values. Calculation or reasoning: journey time is quantitative; shirt colour is the contrasting data type. Final answer: journey time. Check: substitute or compare with the original information to confirm the result fits the question.
Check: Check the quantitative data result against the original information.
Given information: Quantitative data — A data set contains number of pets, travel method and travel method. Name the quantitative variable in the list. Method choice: use the quantitative data method and show each step with the stated values. Calculation or reasoning: number of pets is the required quantitative variable. Final answer: number of pets. 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: Quantitative data — Which survey question collects quantitative data: “What is your shoe size?” or “What is your eye colour?” Method choice: use the quantitative data method and show each step with the stated values. Calculation or reasoning: The question about shoe size collects quantitative responses. Final answer: What is your shoe size?. 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 quantitative data answer.
Create a quantitative data problem with a tempting incorrect answer. Solve it, apply the check, and explain exactly where the incorrect method breaks down.

Quantitative 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 quantitative data representation visible until the final line.
Think of quantitative data as a careful model: make the important values visible, change one thing at a time, and use the check to prove the answer fits.
Start by naming the given information and the exact result required for quantitative data.
Identify the question and the type of data.
