Document Summary

Standardization: a way to make two populations more comparable by adjusting one or both of them to conform to an external standard i. e age, sex. Three components to perform adjusted mortality rate calculations number of deaths, population, a (cid:858)standard(cid:859) population. Direct standardization steps direct age standardization= (cid:4666)(cid:3046)(cid:3047)(cid:3045)(cid:3028)(cid:3047)(cid:3048)(cid:3040) (cid:3046)(cid:3043)(cid:3032)(cid:3030)(cid:3033)(cid:3030) (cid:3045)(cid:3028)(cid:3047)(cid:3032)(cid:3046) (cid:3046)(cid:3047)(cid:3028)(cid:3041)(cid:3031)(cid:3028)(cid:3045)(cid:3031) (cid:3050)(cid:3032)(cid:3034) (cid:3047)(cid:3046)(cid:4667: define a reference pop which serve as the standard against which the test pops will be set. = (cid:888). (cid:889)(cid:883) (cid:1856)(cid:1857)(cid:1872) (cid:1871)/(cid:1872) (cid:1867)(cid:1873)(cid:1871)(cid:1866)(cid:1856) (individuals) before age adjustment miami = 8. 92 deaths/1000 ppl, Alaska = 2. 67 deaths/1000 ppl after age adjustment miami = 6. 92 deaths/1000 ppl, Smr is a ratio, given simply as a number or percentage (no units); ratio of observed to expected deaths death rate of reference pop. Interpretation - white miners pop has 241% higher risk of having tuberculosis than ppl in the male gen pop (reference pop) i. e occupation a is 1. 38 more at risk of dying than standard population; occupation b are.
