La bildo estas kopiita de wikipedia:en. La originala priskribo estas: '''Image of random data plus trend, with best-fit line and different smoothings''' {{GFDL}} The data is 1000 points, with a trend of 1-in-100, with random normal noise of SD 10
115:
Ignoring autocorrelation, a confidence limit for the slope of the fit line is for the raw data (which include 0.01, as it should). For the 10-pt-filtered the limits are slightly narrower at and for the 100pt-filtering the limits are again slightly narrower.

The data is 1000 points (plotted in black), with an increasing trend of 1-in-100, with random normal noise of standard deviation 10 superimposed. The red-line is the same data but averaged every 10 points. The blue line is averaged every 100 points.
