Answer #1

age adjusted death rates are used to compare the groups with different age distributions. For example, a country having a higher percentage of elderly people may have a higher rate of death or hospitalization than a country with a younger population, merely because there is more chance of death or hospitalization of elderly people. Age adjustment can make the different groups more comparable.

We choose "standard" population distribution to adjust death and hospitalization rates. The age-adjusted rates are rates that would have existed if the population under study had the same age distribution as the "standard" population. Therefore, they are summary measures adjusted for differences in age distributions.

The death rates from various conditions are often compared across geographic areas. These comparisons are usually based on directly age-standardized mortality rates. Which of the following best describes what is meant by an age-standardized rate created by the direct method? (Choose one best answer and explain why). The number of events in each age stratum of a standard population is used to create a weighted average rate. The event rates in each age stratum in the standard population are used...

In 2002, the mean age of an inmate on death row was 40.7 years, according to data obtained from the U.S. Department of Justice. A sociologist wants to test the claim that the mean age of a death row inmate has changed since then. She randomly selects 32 death-row inmates and finds that their mean age is 37.9, with a standard deviation of 9.6. Test the sociologist’s claim using a 1% level of significance.
