53. Compare and contrast the various methods or options for dealing with missing data in analyses.
ANSWER:
Several methods or options exist, including (1) reporting missing information as a
separate category, (2) eliminating the case with missing information from all analyses, (3)
eliminating the case with missing information from only analyses using variables with
missing information, (4) substituting values for the missing items, and (5) contacting the
respondent again. The fifth option, contacting the respondent again, is the best way to
get the data in the respondent’s own words but might not be the most viable, especially if
the data were provided anonymously. The four remaining options have pros and cons but
be reminded, if data is harder to get, eliminating data collected becomes more difficult to
justify.
