Question
What is dispersion?
Solution
The term, ‘dispersion’, refers to the scattering of scores about the measure of central tendency. It is used to measure the extent to which individual items or numerical data tend to vary or spread about an average value. Thus, to get a better picture of distribution, we need to use a measure of central tendency and of dispersion or variability.
