Dispersion is the act of spreading people or things (like seeds) out over a large area. Measures of dispersion tell us the degree of variation of values in a sample or population.

How do we calculate variance
You calculate summary statistics: measures of the central tendency and dispersion (spread). The precise statistics would depend on the nature of the data set.
Measures of dispersion are statistical tools that describe the spread or variability of a dataset. They indicate how much the values in a dataset differ from the mean or from each other, providing insights into the consistency or variability of the data. Common measures of dispersion include range, variance, and standard deviation. Understanding these measures helps in assessing the reliability and predictability of statistical analyses.
Are measures of dispersion typically reported as
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.
It's a statistical tool used in psychology. A simple way of calculating the measure of dispersion is to calculate the range. The range is the difference between the smallest and largest value in a set of scores. This is a fairly crude measure of dispersion as any one high or low scale can distort the data. A more sophisticated measure of dispersion is the standard deviation which tells you how much on average scores differ from the mean.
