Unformatted text preview: for country A is 0.74 while the CV for country B is 0.61. By this measure, Country B has a more equal distribution of income. (iii) These results show that the degree of inequality depends on the measure being used. Any inferences from mathematical measures of inequality must take account of the attributes of that measure. 9 Using the GC in Equation 28.7 and taking Ballarat males (60, 70, 80). ΣΣ | y i-y | = (10+20)+(10+10)+(20+10) = 80. So GC = 80/2n 2 y(bar) = 80/(2 × 9 × 70) = 0.0634. Using the same method for the other groups and for the combined male and females groups (with six members), we get the following GCs: Ballarat female 0.0952 Bendigo male 0.351 Bendigo female 0.386 All males 0.275 All females 0.267 This indicates that the: Ballarat female GC > Ballarat male GC Bendigo female GC > Bendigo male GC But Combined male GC > combined female GC....
