Which of the following can be described by all 3 measures of central tendency. Explain why. a. History of diabetes. b. Mortality. c. NYHA heart failure classification. d. Cardiac ejection fraction.
Homework Answers
The correct option is (b) mortality.
Because, we can find out the mean age of death, median age of death and mode age of death. And all of the three values are valid and have good results.
The mean age of death is 81.5 years
The mode age of death is 86 years
The median age of death is 82.5 year's

In the discussion, how do the authors explain the fact that
between digoxin and placebo there were no differences in all-cause
mortality but there were in hospitalizations?
A. They don't.
B. They argue that the sample size may not have been large
enough to detect differences in mortality.
C. They point out the fact that they had a borderline
significant finding for mortality due to worsening heart failure
and suggest that may help with heart failure but may cause bone...
