If I were to track weather or climate over the last 25 years, what would be the best graph to use: bar graph, pie chart, line graph or, pictograph.

 

I am struggling between a line graph or bar graph because a line graph usually compares two variables (independent & dependent) where as a bar graph is useful in comparing data about one thing at different times. The later fits; however, I think a line graph is correct?

If you're looking at temperatures, then a line graph seems the best fit. That's what I've seen primarily in the literature.

 

However, if you're showing multiple variables (like both temperature AND number of tropical storms), then sometimes bar graphs can do better. There is no "one right way," it's more about making the data accessible to your audience.

 

Are you doing a project of some sort? It really depends on exactly what you're trying to show, but a line graph is certainly most common when graphing temps over time.

Thanks for your reply. I'm actually preparing to take the NYSTCE CST in Earth Science (again, I missed it by 17points). I'm trying to recall some of the multiple choice questions. Here's another one:

 

What is the benefit of re-establishing a mine that has been closed down for many years?
