Must know

1Data collection and organisation turn raw responses into useful tables for interpretation.
2Choose categories, tally each response once, and total the frequencies.
3Frequency is the number of times a value or category occurs.
4A group of four vertical marks and one slash means five.

Formula / process

1Data Collection and Organisation questions become easier when the representation and rule are chosen before calculating.
2Keep diagrams, signs, units, and final statements visible.
3Mean, Median, and Mode questions become easier when the representation and rule are chosen before calculating.
4Bar Graphs questions become easier when the representation and rule are chosen before calculating.

Exam traps

1Students often count a tally group incorrectly.
2A group of four vertical marks and one slash means five.
3What does frequency mean?
4Students often find median before arranging data.

Answer frame

Start with the exact keyword or formula before adding explanation.
Use one example, diagram cue, observation, or substitution to support the answer.
For 3 marks: definition, reason, and one supporting point.
For 5 marks: setup, method/process, example, conclusion, and final check.

Notes Write answers

Blank survey cards, coloured counters, trays, and grouped tokens showing data collection and organisation.

ModelData Collection and Organisation

Data Collection and Organisation model

Data collection and organisation turn raw responses into useful tables for interpretation.

Given

The values, diagram, expression, or data from the question.

Rule

Choose categories, tally each response once, and total the frequencies.

Check: Show the representation before the calculation.

Coloured bead stacks, levelled rows, a centre bead, and repeated tokens showing mean, median, and mode.

ModelMean, Median, and Mode

Mean, Median, and Mode model

Mean, median, and mode describe the centre or common value of data.

Given

The values, diagram, expression, or data from the question.

Rule

For mean add and divide; for median arrange and choose middle; for mode find...

Check: Show the representation before the calculation.

Coloured block towers on a blank axis board with sorted counters showing bar graph data representation.

ModelBar Graphs

Bar Graphs model

Bar graphs display categorical data using equal-width bars and a clear scale.

Given

The values, diagram, expression, or data from the question.

Rule

Read the title, axes, scale, and bar height before comparing values.

Check: Show the representation before the calculation.

Dice cubes, blank coins, a coloured spinner, and outcome counters showing chance experiments and randomness.

ModelProbability and Randomness

Probability and Randomness model

Probability describes chance using experiments such as coins, dice, and repeated trials.

Given

The values, diagram, expression, or data from the question.

Rule

List possible outcomes and compare favourable outcomes with total outcomes.

Check: Show the representation before the calculation.
