What type of graph is best for showing trend data over time?

1. Bar graph

2. Line graph

3. Circle graph

4. Pictograph

The correct answer is: Line graph

The line graph is ideal for showing trend data over time because it effectively illustrates changes and patterns in data across a continuous time interval. The continuity of the line helps emphasize the progression of values, making it easier to observe trends, such as increases or decreases, over specified periods. Each point on the line represents a specific data value at a certain time, and connecting these points provides a clear visual representation of how the data evolves. In contrast, bar graphs are generally used for comparing discrete categories rather than illustrating continuous data trends, while circle graphs (or pie charts) are useful for showing proportions of a whole rather than changes over time. Pictographs can also depict data visually but may not clearly convey trends as effectively as line graphs do. Therefore, the line graph is the most suitable choice for analyzing and presenting trend data over time.
