Hi,

We have done a survey on perceptions about healthcare system using
likert scale (1 to 5). One of the demographic variable is age which is
continuous.
I categorized age into 3 groups <40, 40 - 60 and >60 and found that
respondents perceptions/attitude differ age groupwise.
I would like to find the truning point at which the difference exists.
How do I get this?

I am trying to get small age groups say 5 years, but the age ranges
from 18 to 90 years.


pl. advice.
