Suggested answer to exercise: Evaluation of a nurse-run asthma school, 7

Question 7: In the SIP table, what is the mode for the score in the ambulation dimension?

##
Suggested answer

The mode = 0.
Why is this?
The median = 0.
This means that at least half the observations are zero or less.
Te score is a percentage between 0 and 100, so cannot be less than zero.
Zero must be the most frequent observation.
The mode, therefore, is equal to zero.
