Which data presentation method is most suitable to show trends over time in a population study?

Explanation:
To capture how values change over time, you need a presentation that makes changes across the study period easy to see at a glance. A graph does this by plotting time on the horizontal axis and the population measure on the vertical axis, then connecting the points so you can follow the trajectory. This setup highlights trends—whether the population grows, declines, or fluctuates, and how quickly those changes happen—so you can interpret the pattern over the entire study period quickly. A table lists numbers but isn’t as quick to read for trends; a “Pattern” isn’t a standard data presentation method, and guessing isn’t a valid way to present data.
