example 2

Actually, the scattergram is not too bad. It does show us that most people want to retire between the ages of 50 and 70. Overall, the data cloud is distributed quite evenly, but the 45 to 60 year olds are - unsurprisingly - more likely to retire in the 50 to 60 age bracket.

So is there an association or is there not?

-Let's try a different graph. This time, the respondent's age during the interview is summarised in groups, and we compare the mean preferred retirement ages of the age groups.
