Graphs are one of the most common and important ways scientists communicate their results. Learning to understand graphing techniques-the language of graphs-will help you better understand this book. Graphs are visual presentations of data that help us identify trends and understand relationships. We could present a table of numbers, but most of us have difficulty seeing a pattern in a large field of numbers. In a graph, we can quickly and easily see trends and relationships. Below is a graph showing ecological footprints. Often we pass quickly over graphs like these that appear in text, but It's rewarding to investigate them more closely, because their relationships can raise interesting questions. Answer the numbered questions below to make sure you understand graphs and graphing. First make sure you know the parts of a graph. Usually there is a horizontal axis (also known as the "X-axis") and a vertical axis (the "Y-axis"). Usually, there is a dependent variable (Y) that changes in response to an independent variable (X). In this case ecological footprint (Y) varies among countries (X). The questions below are where you should start any time you look at a new graph. For a full discussion of ecological footprints and the many components that contribute to its calculation, see the WWF Living Planet Report.
