The violent crime rate (number of violent crimes per 1,000 residents) in Meadowbrook is 60 percent higher now than it was four years ago. The corresponding increase for Parkdale is only 10 percent. These figures support the conclusion that residents of Meadowbrook are more likely to become victims of violent crime than are residents of Parkdale. The argument above is flawed because it fails to take into account A. Changes in the population density of both Meadowbrook and Parkdale over the past four years. B. How the rate of population growth in Meadowbrook over the past four years compares to the corresponding rate for Parkdale C. The ratio of violent to nonviolent crimes committed during the past four years in Meadowbrook and Parkdale D. The violent crime rates in Meadowbrook and Parkdale four years ago E. How Meadowbrooks’ expenditures for crime prevention over the past four years compare to Parkdale’s expenditures. 答案是D 我對A選項有疑問之前做了幾題這種比例變化的問題發現很多都是沒考慮到base(也就是分母)導致結論被weaken 那為什麼這題用D就可以解釋了??? 如果說者兩個地方的人口數不同則結論好像也不會成立阿有人可以幫忙解惑一下嗎謝謝囉!! -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 123.194.203.188 ※ 編輯: filley 來自: 123.194.203.188 (10/25 22:16)
