Next steps - Some practice problems I am ready to PRACTICE! In the introductory geosciences, we use them for: There are many instances in the geosciences where scientists use a best fit line.

You can also download and print a single sheet for constructing a best fit line with the area method (Acrobat (PDF) 33kB Sep10 08) or the dividing method (Acrobat (PDF) 34kB Sep10 08).

Work through it and the sample problems if you are unsure of how to complete questions about trends and best-fit lines. This page is designed to help you complete any of these types of questions. You may also be asked to approximate the trend, or sketch in a line that mimics the data. If you find yourself faced with a question that asks you to draw a trend line, linear regression or best-fit line, you are most certainly being asked to draw a line through data points on a scatter plot. All of these applications use best-fit lines on scatter plots (x-y graphs with just data points, no lines). For predictive purposes, we might prefer to know how often an earthquake is likely to occur on a particular fault or the possibility of a very large flood on a given river. We want to know if there is a relationship between the amount of nitrogen in the water and the intensity of an algal bloom, or we wish to know the relationship of one chemical component of a rock to another. In introductory geoscience, most exercises that ask you to construct a best-fit line have to do with wanting to be able recognize relationships among variables on Earth or to predict the behavior of a system (in this case the Earth system).
