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.

The stabilization phase (Figure 3) consists of two parts: moving of the wetted particles into the liquid phase and stabilizing the dispersion to prevent re-agglomeration, settling, kickout, or flocculation.
The dispersion polymerization experiments were performed in the glass, sealed cylindrical reactors with a total volume of 50 mL.
One con concerning the use of a dry pigment dispersion is that ink makers who choose this process must make the dispersion themselves.
