They may be used-with considerable caution-when the measurements in the various populations being compared were made in different units. Dividing the dispersion estimates by the location estimates eliminates eliminates the differences attributable to differences in measuring units. However, caution is advised because the measurement methods may have differed in the various populations, giving rise to differences in the dispersion estimates having nothing to do with dispersion in the populations. In other words, there could well be differing levels of measurement error across populations.
In a statistical sense, spread, otherwise known as statistical dispersion, is one of various measures of distribution.

Common measures of central tendency are the mean, median, mode. Common measures of dispersion are range, interquartile range, variance, standard deviation.

Dispersion is an abstract quality of a sample of data. Dispersion is how far apart or scattered the data values appear to be. Common measures of dispersion are the data range and standard deviation.
Both are measures of spread or dispersion.
