In statistics a trend represents the behaviour of a variable over time.
At its simplest, the values of the variable are plotted against time and a visual inspection is used to find a straight line that "fits" the points. The key is to keep the line as close to as many points as possible. This, then, is the trend line.
More sophisticated users will employ the method of least squares to ensure that the line is closest to the points in a mathematically valid sense. Even more sophisticated procedures will require transformations before anything else so that curved lines can be fitted. The choice of the transformation to be used is a technically skilled job.
