A good scatter plot has the independent variable on the x-axis and the dependent variable on the y-axis. Also, the scale of both axes should be reasonable, making the data as easy to read as possible. In these practice problems, we...

In this activity on distance-time graphs, students will understand graphing by analyzing distance-time graphs.

The applet is a target at which green darts are shot either with a strict correlation to each other or without -- the user defines this. A good example of how bivariate data is truly influenced by two variables, possibly dependent upon...
