Central Tendency vs Dispersion In descriptive and inferential statistics, several indices are used to describe a data set corresponding to its central tendency, dispersion, and skewness: the three most important

Most frequency and probability distributions of quantitative variates studied in biology may be interpreted using two opposite but complementary principles: the tendency of observations toward a central value on the one hand, and the dispersion of the same observations about that central value on the ...

48–50 From our previous NMR and ESI MS measurements we know that the carbazole-based double cage can either bind three Cl−, three Br− or two Cl− and one Br−, where the single Br− occupies the central cavity as evident from the signal pattern in the corresponding 1H NMR ...
Dispersion vs Skewness In statistics and probability theory, often the variation in the distributions has to be expressed in a quantitative manner fo
