Materials & Equipment

Lesson 1: Introduction: types of data

Duration: 50 minutes

Starter Activity (5 minutes)

Quick Recall

Write down everything you already know about types of data. Then check against the key terms: key terms from types of data. 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 types of data.
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: types of data. 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 types of data

Plenary (5 minutes)

Check Out

Your student states one thing they learned and one question they still have about types of data.

Lesson 2: Core Concepts: types of data

Duration: 50 minutes

Starter Activity (5 minutes)

Review Previous Lesson

Quick recap: write 3 key points from Lesson 1 on types of data. Check them against the notes below.

Main Content (35 minutes)

Key Fact: Qualitative data is non-numerical — it describes qualities or categories (e.g. eye colour, favourite subject).
Key Fact: Quantitative data is numerical — it can be measured or counted (e.g. height, number of pets).
Key Fact: Quantitative data splits into discrete and continuous.
Key Fact: Discrete data can only take specific values, usually whole numbers (e.g. number of siblings, shoe size).
Key Fact: Continuous data can take any value within a range, including decimals (e.g. height, time, temperature).
Key Fact: Categorical data is a type of qualitative data where values fall into named groups with no order (e.g. blood group, gender).

Practice (10 minutes)

Q: explain the key ideas of types of data

Answer:

Plenary (5 minutes)

Explain Back

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

Lesson 3: Application: types of data

Duration: 50 minutes

Starter Activity (5 minutes)

Quick Recall

Recall the key terms: key terms from types of data. 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: types of data

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 Classify each of the following as qualitative (categorical or ordinal), discrete quantitative or continuous quantitative: (a) hair colour, (b) exam grade (A–U), (c) time taken to run 100 m, (d) number of books read last month. <div class="

(a) Hair colour — qualitative categorical: it is non-numerical and the categories (blonde, brown, black, red, etc.) have no natural order. (b) Exam grade (A–U) — qualitative ordinal: the grades are non-numerical categories but they do have a natural ranking from A (best) to U (worst). (c) Time taken to run 100 m — continuous quantitative: time can take any value within a range, including decimals (e.g. 12.37 seconds). (d) Number of books read last month — discrete quantitative: it is numerical but can only take whole-number values (0, 1, 2, 3, …).

Exam Tips: If a value is counted, it is usually discrete; if it is measured, it is usually continuous. | Shoe size is discrete even though half-sizes exist — it can only take set values. | Temperature is continuous even though it is recorded to a set number of decimal places. | When asked to classify data, give your answer and a brief justification. | Bivariate data questions often link to scatter graphs and correlation.
Common Errors: ✗ Classifying shoe size as continuous because it has half sizes ✓ Shoe size is discrete — it can only take specific values (6, 6.5, 7, 7.5, …), not any value in between. ✗ Saying ordinal data is quantitative because it uses numbers like 1st, 2nd, 3rd ✓ Ordinal data is qualitative — the numbers or ranks represent ordered categories, not measurable quantities. ✗ Confusing categorical and ordinal data ✓ Categorical data has no natural order (e.g. eye colour); ordinal data has a ranking (e.g. small, medium, large). ✗ Thinking continuous data cannot be grouped ✓ Continuous data is often grouped into class intervals for display in histograms or frequency tables.
Stretch & Challenge (Grade 8-9):
  • Synoptic links: explain how types of data connects to another Statistics topic you have studied
  • Real-world: research one real-world use or example of types of data
  • Critical: "What are the limitations of the models used in types of data?"
