Measures of dispersion are called averages of the ‘second order’ because in precise study of dispersion, the deviations of the size of items from a measure of central tendency are calculated (ignoring the signs) and then these deviations are averaged.
Similar to measures of central tendency, a particular value that describes the variability of a collection of data describes the measure of dispersion. The variability in data is measured using the values of the set of data along with the help of central tendency measures.
Various Measures of Dispersion. In many ways, measures of central tendency are less useful in statistical analysis than measures of dispersion of values around the central tendency
• The variance is the usual measure of dispersion in statistical theory , but it has a drawback when researchers want to describe the dispersion in data in a practical way .
And when you go further on in statistics, you’re going to understand the difference between a population and a sample. We’re assuming that this is the entire population of our data.

Descriptive statistics can be divided into two major categories: Measures of Central Tendency; relatively small set of central tendency and dispersion measures from the two categories. Measures of Central Tendency The measures of central tendency describe a distribution in terms of its most “frequent”, “typi-cal” or “average” data value. But there are different ways of
Measures of Dispersion may be either absolute measures or relative measure. Absolute Measures of Dispersion are . a) Range b) Quartile Deviation c) Mean Deviation d) Standard Deviation. Relative Measures of Dispersion are. a) Coefficient of Range b) Coefficient of Quartile Deviation c) Coefficient of Mean Deviation d) Coefficient of Variation.

UNIT 3 CHAPTER ­ 6 MEASURES OF DISPERSION

Dispersion – Deviation and Variance Dispersion measures how the various elements behave with regards to some sort of central tendency, usually the mean. Measures of dispersion include range , interquartile range , variance, standard deviation and absolute deviation.
The absolute measures which are commonly used are: The Range The Quartile Deviation The Mean Deviation The Standard deviation and Variance Relative Measure of Dispersion: These measures are calculated for the comparison of dispersion in two or more than two sets of observations. These measures are free of the units in which the original data is measured. If the original data is in dollar …
And when you go further on in statistics, you’re going to understand the difference between a population and a sample. We’re assuming that this is the entire population of our data. So we’re going to be dealing with the population mean. We’re going to be dealing with, as you see, the population measures of dispersion. I know these are all fancy words. In the future, you’re not going to have
Unit 4: Statistics Measures of Central Measures of Dispersion •Tell you how widely spread out the values are •Most common are Range, Standard Deviation, and Variance Range •The range of a data set is the difference between the maximum and minimum values in the set •Example: >In {4, 6, 9, 3, 7} the lowest value is 3, and the highest is 9. Example: In {4, 6, 9, 3, 7} the lowest value

In statistics, dispersion (also called variability, scatter, or spread) is the extent to which a distribution is stretched or squeezed. Common examples of measures of statistical dispersion are the variance, standard deviation, and interquartile range.

Statistics; Measures of Dispersion; Measures of Dispersion . Measures of dispersion measure how spread out a set of data is. Variance and Standard Deviation. The formulae for the variance and standard deviation are given below. m means the mean of the data. Variance = s 2 = S (x r – m) 2 n. The standard deviation, s, is the square root of the variance. What the formula means: (1) x r – m means

Dispersion in statistics is a way of describing how spread out a set of data is. When a data set has a large value, the values in the set are widely scattered; when it is small the items in the set are tightly clustered. Very basically, this set of data has a small value:
The measures of central tendency are not adequate to describe data. Two data sets can have the same mean but they can be entirely different. Thus to describe data, one needs to know the extent of variability. This is given by the measures of dispersion. Range, interquartile range, and standard
