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 convergence of dispersion and dispersion slope values for the truncated parabolic refractive index and step-index fibers from Figure 4 is shown in Figure 5.
Comparison of Numerical Results with Exact Solutions Available for Step-Index Fibers
As has been noted in Subsection 3.2, unlike the case of the truncated parabolic index profile fiber when the dispersion values converge monotonically, for step-index fibers we observe slight oscillations in the dispersion parameters values.
