Question 1: Look at the following scenario: A village's population has increased from 200 to 350 over ten years. Describe how you would present this data using a bar chart.

Answer: I would draw a bar chart with the years (e.g., 2013 and 2023) on the horizontal axis, and the population numbers on the vertical axis. Two bars would be drawn, with the first bar reaching up to 200 and the second up to 350, showing the increase.

Question 2: A country’s annual rainfall data for five years is: 600mm, 650mm, 620mm, 700mm, and 680mm. Which type of graph would best display this data? Explain why.

Answer: A line graph would be best because it can clearly show the trend of rainfall over the years and how it increases or decreases.

Question 3: Draw a pie chart to show the percentage of land used for agriculture, forestry, and urban areas in a region. The data is: Agriculture 50%, Forestry 30%, Urban areas 20%. Label each section clearly.

Answer: A pie chart divided into three sections: a half (50%) for agriculture, a third (30%) for forestry, and one-fifth (20%) for urban areas. Each section is labeled with its category and percentage.

Question 4: Explain how a climate graph combines two types of data. Use the example of temperature and rainfall over a year.

Answer: A climate graph shows temperature as a line graph and rainfall as bars over the months of the year. The line indicates temperature changes, while the bars show the amount of rainfall each month.

Question 5: You are given data on the population of five cities: City A: 1 million, City B: 2.5 million, City C: 1.8 million, City D: 3 million, City E: 2.2 million. Which type of chart would best compare these populations? Justify your choice.

Answer: A bar chart would be suitable because it allows easy comparison of the population sizes of the five cities side by side.

Question 6: Describe how you would present data showing the number of tourists visiting a country each month over a year.

Answer: I would use a line graph with the months on the horizontal axis and the number of tourists on the vertical axis. Each point would represent the number of tourists in that month, connected by a line to show trends.

Question 7: Sketch a simple bar chart that shows the number of visitors to three different tourist attractions: Attraction X (200 visitors), Attraction Y (350 visitors), and Attraction Z (150 visitors). Ensure the bars are proportional to the data.

Answer: The sketch should have three vertical bars: the first reaching up to 200, the second up to 350, and the third up to 150 on the vertical axis. The bars should be evenly spaced and labeled with the attraction names.

Question 8: A data table shows the annual export values for four countries: Country 1: £50 million, Country 2: £75 million, Country 3: £60 million, and Country 4: £90 million. Describe how you would present this data visually.

Answer: A column chart would be suitable, with each country on the horizontal axis and export values on the vertical axis. The height of each column corresponds to the export value, making comparison easy.

Question 9: Explain the advantages of using pie charts to present data about land use in a region.

Answer: Pie charts clearly show the proportion of different types of land use relative to each other, making it easy to see which land use covers the largest or smallest area at a glance.

Question 10: You are asked to compare two sets of data: the average temperatures of two cities over a year. One set is 10°C to 20°C, and the other is 15°C to 25°C. Which chart type would you use and why?

Answer: A line graph or side-by-side bar chart would be suitable because they can compare temperature ranges and trends for both cities effectively.
