Question

The measure of dispersion is changed by a change of

Answer 1

Answer:

Explanation:

Measures of dispersion or variation. As a result, a change in the value of any item will have its effect on the magnitude of mean deviation.  The values of extreme items have less effect on the value of the mean deviation.  As deviations are taken from a central value, it is possible to have meaningful comparisons of the formation of different distributions.

Answer 2

The measure of dispersion is changed by the change of scale.

Explanation:

• In statistics, dispersion can be used in two senses:

1. The scatteredness of the values of a variable due to variation among themselves is dispersion.
2. The scatteredness of the deviations from a measure of central tendency or any other fixed value.

• Dr. Bowley defined dispersion as, "Dispersion is the measure of variation of the items."
• There are two types of measures of dispersion. They are absolute measure and relative measure.
• For a measure of dispersion to be good, it should be rigidly defined, based on all the observations, simple and easy to calculate, and amicable for algebraic treatment.
• It should also be least affected by fluctuations of sampling and not be unduly affected by extreme items.
• The measure of dispersion can be changed by the scale.
