When would you choose to use a line graph in your analysis?

A line graph is particularly effective when demonstrating trends over time because it visually represents changes in values across a continuous variable, typically time. This format allows for easy identification of patterns, such as increases or decreases, fluctuations, and overall trends.

By connecting individual data points with lines, a line graph illustrates the progression of data in a way that highlights the relationships between time intervals and their corresponding values. This makes it especially useful in fields such as economics, environmental studies, public health, and any analysis where time series data is relevant. Other options, while useful in their contexts, do not capture the same emphasis on temporal trends that a line graph effectively provides.
