Which type of graph is best for presenting temperature data?

• A. Bar chart
• B. Pie chart
• C. Line graph
• D. Scatter plot

Answer: (C)

Temperature data are continuous measurements that change over time, so you want a visualization that clearly shows how values evolve and trend. A line graph does that by connecting successive readings with a line, making it easy to see when temperatures rise or fall and how quickly they change across hours or days. Bar charts, while useful for comparing discrete categories, break the sequence into separate columns and don’t emphasize the trend over time. Pie charts display parts of a whole at a single moment and aren’t meant for showing changes over time. Scatter plots illustrate relationships between two variables and aren’t ideal for conveying a single variable’s progression through time. So, a line graph is the most effective way to present temperature data.
