Characteristics of Statistics

The characteristics of statistics are

  1. Statistics deals with the behavior of aggregates or large groups of data. It has nothing to do with what is happening to a particular individual or object of the aggregate.
  2. Statistics deals with aggregates of observations of the same kind rather than isolated figures.
  3. Statistics deals with variability that obscures underlying patterns. No two objects in this universe are exactly alike. If they were there would have been no statistical problem.
  4. Among the important characteristics of statistics is that statistics deals with uncertainties as every process of getting observations whether controlled or uncontrolled involves deficiencies or chance variation. That is why we have to talk in terms of probability.
  5. Statistics deals with characteristics or aspects of things that can be described numerically by counts or measurements.
  6. Statistics deals with aggregates that are subject to several random causes, e.g., the heights of persons are subject to several causes such as race, ancestry, age, diet, habits, climate, etc.
  7. Statistical laws are valid on average or in the long run. There is no guarantee that a certain law will hold in all cases. Statistical inference is therefore made in the face of uncertainty.
  8. Among the important characteristics of Statistics is that statistical results might be misleading and incorrect if sufficient care in collecting, processing, and interpreting the data is not exercised or if the statistical data are handled by someone not well-versed in the subject matter of statistics.
