It means that they survived an average of 22 years.Hi,
"The data showed that respondents with the most positive attitudes survived a median of 22 years after their initial interview, "
I hope someone could have a look for me. I do not think I get this sentence exactly, does it mean - "Respondents with the most positives attitudes survived in the middle of 22 years (around 11 years) after their initial interview." Or " Around a half of these respondents (around 320 people) with the most positive attitudes survived 22 years after their initial interview." The word "median" here refers to the amount of the time or the respondents ?
What does this sentence mean?
Thanks for your help.
... The researchers found that people who view aging positively live longer than people who view it negatively. This study began 26 years go and took place in a small town in the Midwest. The participants were 640 men and women who were 50 to 90 years old at the the time. The subjects were asked to agree or disgree with statements about aging, like "As you get older, you become less useful" and "Older people can't learn new skills." The data showed that respondents with the most positive attitudes survived a median of 22 years after their initial interview, while those with negative views lives just 15 years - a difference of seven years.
