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.
Genus and species. The scientific nomenclature of biological species clearly identifies the organism named and the person who first named the species. The genus (always capitalized) and the species (not capitalized) are given in italics. For example, the Philippine brown deer is Rusa marianna, and the dove tree, found in parts of China, is Davidia involucrata.
