If the number is in a certain data set, then that number is the average of that set. If ever the number in a certain data set is not the same, then the numbers must be gathered and computed to come up with just one number to represent them all. The method that is used the most is the arithmetic mean.
â¢ Genus is the first name, and the species is the second name of a scientific name of any organism. â¢ Genus ranks higher compared to species in the hierarchy of taxonomy. â¢ Two fertile animals from one species can produce a fertile progeny, whereas two animals from one genus could or could not do so.
In biology, a species (abbreviated sp. , with the plural form species abbreviated spp. ) is one of the basic units of biological classification and a taxonomic rank.pecies hypothesized to have the same ancestors are placed in one genus, based on similarities. The similarity of species is judged based on comparison of physical attributes, and where available, their DNA sequences.
