Mean,
median, and mode are commonly used in different statistical analyses. However,
these are not so reliable to be used as basis for making decisions. In a car manufacturing
outlet for instance, an average size is used in the manufacture of a brand of a
vehicle. However, this average value is not as important as the degree of
deviation of the data points. Hence, the measure of standard deviation is a
very important one. It provides information about the degree at which different
sets of data vary. For industries that need this value on the go, you can
always trust the z-score calculator.
