Dispersion

In statistics, the placement of data points along a chart relative to an average or mean line. Dispersion is important to finance as the data points of say, a stock, determine the mean, which in turn helps determines the stock's trend. Dispersion is also used to determine volatility: data points all over the chart indicate that a stock has wild fluctuation in price.
