(a) Calculation of SD involves all the values of the given variable. If the skewness is less than -1(negatively skewed) or greater than 1(positively skewed), the data are highly skewed. obesity or high blood pressure) and in this case the distributions are usually unimodal. To study the extent or the degree of economic inequality prevailing among the people of various professional categories, construction of a Lorenz Curve and estimation of the Gini Co-efficient is the order of the day as it helps the planners to take effective future development policies for the people indiscriminately. Measures of Dispersion - Toppr-guides Web2. The COVID-19 pandemic has also instigated the development of new ozone-based technologies for the decontamination of personal WebMeaning of Dispersion: Dispersion is the extent to which values in a distribution differ from the average of the distribution. PAPER QUANTITATIVE TECHNIQUES 3 - icpau.co.ug It is thus known as the Curve of Concentration. Thus mean = (1.2+1.3++2.1)/5 = 1.50kg. is the data made up of numbers that are similar or different? Measures In order to avoid such limitations, we use another better method (as it is claimed) of dispersion known as the Mean Deviation. The performances of two Batsmen S and R in five successive one-day cricket matches are given below. They indicate the dispersal character of a statistical series. The interquartile range is a useful measure of variability and is given by the lower and upper quartiles. 1. Therefore, the Range = 12 1 = 11 i.e. Webwhat are the advantages of standard deviation? QT-2022 Lecture Note - 1 Preface CONTENTS Quantitative Central tendency gets at the typical score on the variable, while dispersion gets at how much variety there is in the scores. The first quartile is the middle observation of the lower half, and the third quartile is the middle observation of the upper half. RANGE. WebThe control of infectious diseases can be improved via carefully designed decontamination equipment and systems. The dotted area depicted above this curve indicates the exact measure of deviation from the line of Absolute-Equality (OD) or the Egalitarian-Line (dotted Line) and hence gives us the required measure of the degree of economic inequality persisting among the weavers of Nadia, W.B.
