Subject: Handling survey data issue
Good morning,
I have a survey from a client that has a variable, say number of
pills taken per day, that is coded as a numeric - in part. The
survey respondents were asked to state the number of pills and this
number was recorded. But, for those who took more than 10, the
answer was recorded as 10+. I have to calculate a mean and do other
estimations. How do I handle the 10+? Any suggestions on handling
the 10+? Is there a way to estimate a number for 10+? I seem to
recall a paper years ago that addressed the issue of a censored
answer such as 10+ to find a number that could then be used in
calculations. This should be a common problem. My next question, of
course, is: Is there an R function for this?
Thanks for any help.
