The {eq}z-{/eq}score is a standardized value that gives how many standard deviations a given data lies above or below the mean. This score makes the comparison of datasets of different units possible. It is calculated as shown below: ...
values are binned to create histograms. The taller “peaks” of the histogram indicate where more common data values cluster, calledmodes. A cluster of tall bins is sometimes called amodal range. A histogram having one tall peak is calledunimodalwhile two peaks is referred to asbimodal...
While it may be no surprise that the outer tails of a normal are heavier than those of a uniform distribution or a triangular distribution, it is a surprise that the outer tails of a normal are heavier than those of the six heavy-tailed distributions shown in figures 3 and...
