Define dispersion. Dispersion is the extent to which values in a distribution vary from the average of the distribution. Name the two types of measures. Measures of dispersion can be classified as absolute measures and relative measures.

Define absolute measures of dispersion. Absolute measures of dispersion are expressed in terms of original units of a data. List the methods of absolute measures of dispersion. The methods of absolute measures of dispersion are: i Range ii Quartile deviation iii Mean deviation iv Standard deviation Q. What are relative measures of dispersion? Relative measures of dispersion are expressed in terms of percentage and ratios.

Coefficient of range, coefficient of quartile deviation, coefficient of mean deviation and coefficient of variance are the relative measures of dispersion.

Why is it important to know the spread of values? The averages tell only one aspect of a distribution, that is, a representative size of the values. It important to know the spread of values to understand averages in a better manner. Discuss the features of a good measure of dispersion? The following are the features of a good measure of dispersion: i It should be simple to understand and easy to calculate. Distinguish between absolute and relative measures of dispersion.

Following are the points of difference between absolute and relative measures of dispersion: 1. Absolute Measures of Dispersion Absolute measures of dispersion are expressed in terms of original units of a data.

The methods of absolute measures of dispersion are:. Relative Measures of Dispersion Relative measures of dispersion are expressed in terms of percentage and ratios. The methods of relative measures of dispersion are coefficient of:. State the limitations of absolute measures of dispersion. Following are the limitations of absolute measures of dispersion: i Absolute measures may give misleading ideas about the degree of variation.

What are the objectives of measuring dispersion? The objectives of measuring dispersion are: i To determine the reliability of the average ii To compare the variability of two or more distributions iii To facilitate the use of other statistical methods iv To know the nature and hence, control the reasons of variation Q. Define range. Range is the difference between the highest value and the lowest value in a series.

Give the formula for finding range. What is the coefficient of range? Coefficient of range is the ratio of the difference between the highest and lowest values of the series to the sum of the lowest and highest values of the series. State the merits of range. Following are the merits of range: i It is easy to understand and calculate. What are the limitations of range? Following are the limitations of range: i Range is unduly affected by extreme values.

These solutions for Measures Of Dispersion are extremely popular among Class 11 Commerce students for Economics Measures Of Dispersion Solutions come handy for quickly completing your homework and preparing for exams. A measure of dispersion is a good supplement to the central value in understanding a frequency distribution. The study of the averages is only one sided distribution story. In order to understand the frequency distribution fully, it is essential to study the variability of the observations. The average measures center of the data whereas the quantum of the variation is measured by the measures of dispersion like range, quartile deviation, mean deviation and Standard Deviation. For example, if a country has very high income group people and very low income group people, then we can say that the country has large income disparity. Standard Deviation is the best measure of dispersion as it satisfies the most essentials of the good measure of dispersion.
