Question 1: You are given a table showing the average monthly rainfall (mm) for two cities, City A and City B, over a year. Describe how you could visually compare the rainfall patterns in these two cities.

Answer: A suitable method would be to create a line graph with months on the x-axis and rainfall in mm on the y-axis, plotting two lines—one for each city—to compare their monthly rainfall patterns visually.

Question 2: Explain the main advantage of using a bar chart instead of a pie chart when comparing the population sizes of different countries.

Answer: A bar chart makes it easier to compare the sizes of different populations directly because the length of each bar accurately reflects the differences, whereas pie charts are better for showing proportions within a whole.

Question 3: A pie chart shows the percentage distribution of land use in a region: 40% agriculture, 25% urban, 20% forest, and 15% water. Describe how you could convert this data into a bar chart.

Answer: Create a bar for each land use category with heights proportional to their percentages: agriculture would have a bar at 40 units, urban at 25 units, forest at 20 units, and water at 15 units, with categories labeled on the x-axis.

Question 4: Draw a simple line graph to show the change in temperature over a week, with the temperature data: Monday 15°C, Tuesday 17°C, Wednesday 16°C, Thursday 18°C, Friday 20°C, Saturday 19°C, Sunday 21°C. Label the axes appropriately.

Answer: A correct graph would have the days of the week on the x-axis and temperature in °C on the y-axis. The line would connect points representing each day's temperature, showing an overall increasing trend with slight fluctuations.

Question 5: A scatter plot shows the relationship between hours studied and test scores for a class. What does a positive correlation in this plot indicate?

Answer: It indicates that as the number of hours studied increases, the test scores tend to increase as well, suggesting a positive relationship between study time and performance.

Question 6: Describe how a climate graph (combining a bar chart and line graph) can be used to present temperature and rainfall data for a specific location.

Answer: A climate graph uses bars to show monthly rainfall and a line to show average temperature for each month, allowing viewers to compare how temperature and rainfall vary throughout the year at a glance.

Question 7: Sketch a simple bar chart to show the population of three cities: City X with 500,000 people, City Y with 1,200,000 people, and City Z with 800,000 people. Label each bar clearly.

Answer: A correct sketch would have three bars with heights proportional to their populations, with labels 'City X', 'City Y', and 'City Z' on the x-axis, and the y-axis scaled to accommodate the largest population.

Question 8: You are presented with data showing the number of visitors to a national park over a year. How could you present this data to highlight seasonal trends?

Answer: A line graph plotting month on the x-axis and number of visitors on the y-axis would clearly show peaks and troughs, indicating busy and quiet seasons within the year.

Question 9: Explain the difference between qualitative and quantitative data in the context of geographical data presentation.

Answer: Quantitative data involves numerical measurements like rainfall or population, which can be measured and plotted on graphs, while qualitative data describes qualities or categories, such as land use types or tourist satisfaction levels.
