Understand Choosing data to collect
Use real data and precise language to work confidently with choosing data to collect. 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 choosing data to collect, the final written answer should make that exact relationship visible rather than hiding it inside an unexplained result.
Start here
Choosing data to collect: 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 choosing data to collect representation visible until the final line.
Picture the idea
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 choosing data to collect.
Check as you go
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 choosing data to collect answer.
Given information: Choosing data to collect โ 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.
Identify the question and the type of data.
Organise values carefully and choose a suitable display or summary.
Calculate or read the relevant evidence.
Write a contextual conclusion supported by values. Record the check explicitly for choosing data to collect.
Step-by-step method

What you need first
Recognise the vocabulary: data, frequency, sample.
Be able to explain the purpose of choosing data to collect before calculating.
Keep the relevant values, units and representation visible while you work.
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 choosing data to collect.

Given information: Choosing data to collect โ Choose the reliable next step for a sample of 20 pupils. Method choice: use the choosing data to collect 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.

Secure example
Use the normal method
Given information: Choosing data to collect โ State the strongest conclusion for a questionnaire. Method choice: use the choosing data to collect 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 choosing data to collect result against the original information.
Challenge example
Stretch the idea
Given information: Choosing data to collect โ Select the method that avoids a misleading claim for a line of best fit. Method choice: use the choosing data to collect 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.
Exam-style example
Show your reasoning
Given information: Choosing data to collect โ Complete the analyst's advice for a school survey. Method choice: use the choosing data to collect 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.
Exam tip: Underline the units and command word. Show the key calculation and write the answer in context.
Common mistakes
Using a vague conclusion without numbers. This is a key trap when answering choosing data to collect questions.
Choosing a display that hides an important feature.
How to check your answer
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 choosing data to collect answer.
