Lesson 1: Introduction: statistical enquiry cycle

Duration: 50 minutes

Starter Activity (5 minutes)

Quick Recall

Write down everything you already know about statistical enquiry cycle. Then check against the key terms: key terms from statistical enquiry cycle. Use a mini-whiteboard or paper.

Main Content (35 minutes)

Parent/Teacher Guide:
Before lesson: Read the script below. Pre-teach key vocab: key terms from statistical enquiry cycle.
If stuck: Re-read the revision notes (link above), then break the content into smaller steps.
Extension: See the Stretch & Challenge ideas in Lesson 4.
Teaching Script (35 mins):
Mins 0-5 - Hook: "Today: statistical enquiry cycle. By the end you will be able to answer exam questions on it unaided. It connects to the rest of Statistics because the ideas here recur across the spec."
Mins 5-20 - Direct Instruction: Work through the core ideas below one at a time; after each, ask your student to explain it back in their own words.
Mins 20-30 - Guided Practice: Model the worked example together, then let your student attempt the first practice question with guidance.
Mins 30-35 - Independent Practice: 2-3 practice questions from Lesson 3 below, with immediate feedback.
First Look

Start with the revision notes summary, then attempt: explain the key ideas of statistical enquiry cycle

Plenary (5 minutes)

Check Out

Your student states one thing they learned and one question they still have about statistical enquiry cycle.

Lesson 2: Core Concepts: statistical enquiry cycle

Duration: 50 minutes

Starter Activity (5 minutes)

Review Previous Lesson

Quick recap: write 3 key points from Lesson 1 on statistical enquiry cycle. Check them against the notes below.

Main Content (35 minutes)

Key Fact: The Statistical Enquiry Cycle (SEC) is a structured approach to carrying out a statistical investigation.
Key Fact: The five/six stages are: Plan, Collect, Process, Present, Interpret and Evaluate.
Key Fact: Some specifications list five stages (combining Interpret and Evaluate); others list six.
Key Fact: Plan: Define the hypothesis, identify variables, decide on methods and sample.
Key Fact: Collect: Gather data using your chosen method — survey, experiment, observation or secondary sources.
Key Fact: Process: Clean, organise and summarise the data — calculate statistics, group data, deal with anomalies.

Q: explain the key ideas of statistical enquiry cycle

Answer:

Plenary (5 minutes)

Explain Back

Your student teaches the key points back to you without looking. Fill any gaps immediately.

Lesson 3: Application: statistical enquiry cycle

Duration: 50 minutes

Starter Activity (5 minutes)

Quick Recall

Recall the key terms: key terms from statistical enquiry cycle. Define each in one sentence.

Main Content (35 minutes)

Parent/Teacher Guide: Let your student attempt each question alone first, then compare with the model answer. Award method marks for correct working even if the final answer is wrong.

Work through the practice questions on the revision notes page for this topic.

Plenary (5 minutes)

Error Review

Review any questions answered incorrectly. Identify whether the error was knowledge, method, or reading the question.

Lesson 4: Exam Practice: statistical enquiry cycle

Duration: 50 minutes

Starter Activity (5 minutes)

Command Words

Review what these command words require: state (one point), describe (say what happens), explain (say why), compare (both sides), evaluate (judgement).

Extended Answer

Extended question: Full-Mark Response A student investigates whether taller people have larger shoe sizes. They collect heights and shoe sizes from 30 classmates, calculate the mean for each group, draw a scatter graph and conclude the hypothesis is supported. Identify the stage for each action. <div class="

1. 'They collect heights and shoe sizes from 30 classmates' — Collect stage: gathering raw data. 2. 'Calculate the mean for each group' — Process stage: summarising the data using a statistic. 3. 'Draw a scatter graph' — Present stage: displaying the data visually. 4. 'Conclude the hypothesis is supported' — Interpret stage: drawing a conclusion and relating it to the hypothesis. The student should also carry out the Evaluate stage, assessing whether 30 classmates is a representative sample, whether there may be bias (e.g. all same age), and whether the method could be improved.

Exam Tips: Learn the stages in order — exam questions often ask you to name or sequence them. | When asked which stage an action belongs to, think about what the action achieves. | Calculating statistics is 'Process'; drawing a chart is 'Present'; writing a conclusion is 'Interpret'. | Evaluation questions are common — always comment on bias, sample size and method. | Remember the cycle can be iterative — evaluation leads to improvement and re-planning.
Common Errors: ✗ Confusing the Process and Present stages ✓ Process involves calculating summary statistics and cleaning data; Present involves drawing charts and diagrams. ✗ Thinking the cycle is strictly one-way ✓ The cycle is iterative — evaluation often leads back to planning improvements. ✗ Putting 'drawing conclusions' in the Present stage ✓ Drawing conclusions is part of the Interpret stage; Present is for creating visual displays only. ✗ Forgetting to link conclusions back to the hypothesis in the Interpret stage ✓ Always relate your findings explicitly to the original hypothesis, stating whether the data supports it.
Stretch & Challenge (Grade 8-9):
  • Synoptic links: explain how statistical enquiry cycle connects to another Statistics topic you have studied
  • Real-world: research one real-world use or example of statistical enquiry cycle
  • Critical: "What are the limitations of the models used in statistical enquiry cycle?"
