Important points: crime is going down, phenomena we can only measure with victimization surveys, standard errors for violent victimizations. find the big points. Ncvs benefit = we can measure attempted crimes. Standard deviation = dispersion of estimate about its true mean. Standard error = standard deviation that is corrected for sample size. When you read an article, think of the real fundamental principles; (cid:1) (cid:1) numbers are not important (cid:1) (cid:1) (cid:1) (cid:1) Crime rate = a really good measure of victimization risk: risk = probability of being victimized, roughly speaking, crime rates are also proportional to waiting time between victimizations. Crime rate = number of crime events / number of targets at risk. The probability of victimization is the crime rate. The waiting time to next victimization is 1/crime rate.
