Measures of Dispersion and its Types- Absolute and Relative
Dispersion is the act of dispersing from one location. One may say that people left the arrival place in dispersion. Similar to this, dispersion in statistics refers to the distribution of observations away from a central location. The mean, median, and mode are three different metrics of central tendency, as we have seen in earlier blogs. However, not all values are equal to the central value; instead, most of them fall within its range, with some values being far from it. Furthermore, we employ a variety of dispersion techniques to determine the extent of the spread. The average's precision decreases with increasing spread. A single number that represents the complete collection of data is used to calculate measures of central tendency. However, that primary value won't always match up with every observation. Some might differ more than others. Measures of dispersion are used to quantify this degree of variation. Assume that ten pupils in the class took the test, and the ...
