What are the major trends shown? [2] Suggested Answer: ✓ Share of population at least partially vaccinated in all countries regardless of income levels increased between January 2021 and October 2021. ✓ The extent of increase was slowest in low income countries but highest in high income countries. ✓ The higher the level of income, the higher the share of population at least partially vaccinated. (Any one of the above responses will gain 1 mark. Other valid responses will be accepted too.) Good sample response: “The share of population at least partially vaccinated generally increased across all (income) groups from January 2021 to October 2021. Higher income gro ups experienced a great increase in share of population at least partially vaccinated while lower income groups experienced low to minimal increase of share of population at least partially vaccinated.” [Abdul Halim. 22S06H]: Mark Scheme: 1 mark for each correct observation about a major trend from Figure 1. Examiners’ Comments: Most students identified and accurately described two major trends from Figure 1. Mere regurgitation of data was infrequent. Revision: A trend is the general direction in which something is developing or changing over time. A trend can often be found by establishing a line chart. A trendline is the line formed between a high and a low. If that line is going up, the trend is up. If the trendline is sloping downward, the trend is down. There is no need to provide numerical values unless the question asks you to calculate or to justify why.
