Complete the two different forms of presentation shown below for the population data in Appendix 1. Explain the advantages of each form of presentation.

Mark scheme

Marking points from the official mark scheme (Oct/Nov 2015). The mark or mark type is shown in brackets.

1. [8] 2 marks for each form of presentation correctly plotted = 1 mark for accuracy and 1 mark for correct labelling of the chart.
2. [8] Plus 2 additional marks for explaining why it is suitable to use for this data.
3. [8] e.g.: A pie chart shows the proportion or percentage of each age group (1) and this clearly shows which age group has the highest proportion or the smaller proportion in the total population (1).
4. [8] A bar chart is suitable to show the different numbers of the population information (1). It makes it easier to distinguish between the highest categories and the lowest categories of the population statistics (1).
5. [8] Downtown Population data in 000's: Age: 0–16 (Number of people: 125), 17–40 (Number of people: 250), 41–65 (Number of people: 500), 66+ (Number of people: 125).
6. [8] [Figure showing correct Pie Chart with 12.5%, 25%, 50%, 12.5% for 0-16, 17-40, 41-65, 66+ respectively with correct labels]. NB – accept 12%/13%/12.5% for 0–16 and 66+
7. [8] [Figure showing correct Bar Chart with Age categories 0-16, 17-40, 41-65, 66+ on x-axis and Number of people (000's) on y-axis, with bars at 125, 250, 500, 125 respectively].
8. [12] Relevant points might include:
9. [12] 2013: Gross Profit Margin 66.66%, Profit (net) margin 16.66%, ROCE 25%.
10. [12] 2014: Gross Profit Margin 75%, Profit (net) margin 12.5%, ROCE 25%.
11. [12] Profit (net) margin = $500000 for both years (L1).
12. [12] Knowledge/Application/Analysis/Evaluation – award up to 10 marks using the levels-based mark scheme below.
13. [12] Level 3: At least 2 x Level 2 correct calculations + 9-10 marks for well justified conclusions as to whether Rafael should be pleased with the profitability of the business.
14. [12] Level 2: 7-8 marks for some limited judgement shown in conclusion as to whether Rafael should be pleased with the profitability of the business. 4-6 marks Calculation of profitability ratios.
15. [12] Level 1: 1-3 marks Outline of what is meant by the profitability ratios or statements on the differences in the figures in Appendix 2. 1 mark for each L1 statement (max of 3 marks) e.g. yes because Rafael has an increase in sales revenue.
16. [12] Level 2 - 1 x L2 calculation can gain 4 marks and a further mark can be awarded for each additional L2 calculation (max 6 marks) e.g. the gross profit margin in 2014 is 75%. (4 marks for L2 answer)
17. [12] Level 3 - For L3 to be awarded there needs to be at least two L2 calculations awarded and then a well justified conclusion as to whether Rafael should be pleased with the profitability of the business.
