(dis-per'zhon) [L. dispersio, scattering]
1. The act of dispersing.
2. That which is dispersed.
3. In statistics, the degree to which data are distributed widely (or closely) to a central point, such as the mean or mode.

coarse dispersion

Suspension (3).

colloidal dispersion

A mixture containing colloid particles that fail to settle out and are held in suspension. They are common in animal and plant tissues; the protoplasm of cells is an example. Particles of colloidal dispersions are too large to pass through cell membranes. Such dispersions usually appear cloudy.

molecular dispersion

A true solution.

Q-T dispersion

The difference between the longest and the shortest Q-T interval recorded by electrocardiography. High levels of Q-T dispersion (e.g., greater than 100 msec) may be a risk factor for life-threatening ventricular arrhythmias.

QTc dispersion

In electrocardiography, variation in the corrected QT interval in different leads. This has been correlated with an increased incidence of ventricular arrhythmias and sudden death.
