Tr Jain Vk Ohri 2019 Solutions for Class 11 Commerce Economics Chapter 11 Measures Of Dispersion are provided here with simple step-by-step explanations. or,   Q3 = Size of 9th item If the index of dispersion is larger than 1, a dataset is … Given the following data-set, calculate range and the coefficient of range: Highest value (H) = 11.5 Subscribe to our YouTube channel to watch more lectures. of the series is 5.5 and Coefficient of the Q.D. Thus, we calculate the deviation of values from 26. In statistics, the quartile coefficient of dispersion is a descriptive statistic which measures dispersion and which is used to make comparisons within and between data sets. You will be surprise that these three types of dispersion are called chromatic dispersion. Relative In the form of ratio or percentage, so is independent of units It is also called Coefficient of Dispersion BirinderSingh,AssistantProfessor,PCTE 6.  ⇒   R  = 90 Following data relate to the age-difference of husbands and wives of a particular community. e.g. Find out mean deviation from mean. R= 35 − 15= 20 Calculating Standard deviation through Step deviation method: Calculation of mean deviation from median. , Q.D.=29.5-18.52or, Q.D.=112⇒ Q.D.=5.5Coefficient of Quartile deviation of the dispersion of a community.
