Correlations in data

http://www.mathsisfun.com/data/correlation.html
These plots illustrate the levels of correlation between two sets of data.  The first plot is a perfect correlation, which means that the data vary at the same rate over the same parameter.  When data are more loosely correlated, it means that they respond differently to the same input.  So this assumes that each of the data are dependent on a third parameter, like time or space for example.
