What to Focus On

  • Dispersion shows spread or variation in data.
  • It helps compare series with the same average but different distribution.
  • Dispersion is an average of deviations, so it is also called an average of the second order.
  • Small dispersion means greater reliability of the average.
  • Large dispersion means less uniformity and less consistency.
  • Dispersion is useful for comparison and control of variability.
  • Simple to understand and easy to compute.
  • Based on all observations.
  • Suitable for algebraic treatment.

Common Mistakes to Avoid

Average alone is enough to describe a series.

Range uses all values of the distribution.

Range can always be calculated in open-end classes.
