Presenting genuine data in tables and graphs, analysing it with accurate mathematics and all steps shown, drawing a conclusion tied to the objectives, and writing up the report.
5 narrated scenes. Press play, listen and read along — the points appear as they are explained. Use ‹ Prev / Next › or the scene bar to jump to any scene.
Presentation, analysis and conclusion carry 19 of the 30 project marks. This lesson shows exactly what earns them.
Narration uses your device’s built-in voice. No sound? Switch to “Captions only” — the captions advance on their own.
Copy these into your notebook in your own words — that is how they stick.
Genuine raw data; at least one table (title, headings) and one graph/chart (title, labels, scale/key). No raw data → ≤ 2 marks.
Bar: categories. Pie: parts of a whole. Line: trend. Histogram: grouped continuous data. Scatter: relationship.
Accurate use of syllabus mathematics; formulae and ALL steps shown; relates to the objectives.
Based on the analysis, related to the objectives; add limitations and improvements.
Logical flow, correct grammar; poor organisation → 1 mark.
Maximum 1 000 words excluding quotations, sources, charts, graphs, tables, pictures, references, appendices.
Acknowledge all sources; submit one document (preferably PDF) with images embedded.

Question 1 [9 marks]
A student surveyed 10 classmates on the number of hours they study per week: 5, 8, 3, 10, 6, 7, 8, 4, 9, 8.
(a) Calculate the mean, median, mode and range of the data, showing the steps. [6]
(b) Suggest which graph is most suitable to display how many students study 0–5, 6–10 hours, and explain. [2]
(c) Write ONE sentence of analysis that relates the results to the objective “to find the average study time”. [1]
Question 2 [10 marks]
In a project comparing hire purchase with cash for a television, Store A had cash $2 000 and hire purchase $2 380, and Store B had cash $1 950 and hire purchase $2 250.
(a) Calculate the percentage extra paid by hire purchase at each store, to 1 decimal place. [4]
(b) Write a conclusion of 2–3 sentences based on your results. [3]
(c) State TWO limitations of the project and ONE improvement. [3]
