to understand the difference between survival time and life expectancy. Survival time is the actual time from the present moment until death, whereas life expectancy is the average... (or arithmetic mean) survival time. Some persons will live shorter than the life expectancy, others may live longer. For example, if hypothetically the survival times for 5 year-olds... years -- the child could only live shorter (10 or 20) or longer (90). In an actual case, the possible survival times may vary from 0 to 100 additional years, but the principle would...

is the arithmetic mean of the actual survival times of all the individuals. For example, consider a cohort of just five individuals all born on the same day. If they live 10, 20, 50, 60... their life expectancy would be (10 + 20 + 40)/3 = 23.3 additional years. Median survival time The median survival time is the middle survival time for the cohort if the survival times..., respectively, then the median survival time would be 50 years. The survivors at age 40 have medial survival time of 20 additional years. In Table 1 the median survival time...
