What are the properties of a good measure of dispersion?

Properties of a Good Measure of Dispersion:

The following are the properties that a good measure of dispersion should possess:

1. Rigidly Defined: A good measure of dispersion should be properly and rigidly defined so that it does not create any problem for the reader in analysing the data.

2. Easy to Calculate: Another important property of a good measure of dispersion is that it should be easy to calculate.

3. Based on all Observations: A good measure of dispersion should be based on all the observations of the data.

4. Easy to Understand: It is an another important property of a good measure of dispersion to be easily deducible by the reader.

5. Least Affected by the Sampling Fluctuations: Any good measure of dispersion should be least affected by the fluctuations persisting in the sample values.

6. Unaffected by Extreme Values: A good measure of dispersion should be least affected by the extreme values of the data.

7. Suitable for Further Treatment: A good measure of dispersion should be suitable to be used for the further statistical treatment.
