What's the difference between statistics and variability?

Statistics


Definition:

  • (n.) The science which has to do with the collection and classification of certain facts respecting the condition of the people in a state.
  • (n.) Classified facts respecting the condition of the people in a state, their health, their longevity, domestic economy, arts, property, and political strength, their resources, the state of the country, etc., or respecting any particular class or interest; especially, those facts which can be stated in numbers, or in tables of numbers, or in any tabular and classified arrangement.
  • (n.) The branch of mathematics which studies methods for the calculation of probabilities.

Variability


Definition:

  • (n.) The quality or state of being variable; variableness.
  • (n.) The power possessed by living organisms, both animal and vegetable, of adapting themselves to modifications or changes in their environment, thus possibly giving rise to ultimate variation of structure or function.

Example Sentences:
