 Working
through the Data
6.3 Review data for errors
Sources of error
Quality of data is improved if errors
can be corrected at the source, e.g. when self-completed
questionnaires
are turned in during a program session.
Review forms
immediately for obvious errors e.g.,
- missing data
- several
boxes checked instead of one
- illegible writing
Ask the respondent to correct the
problem.
Other sources of error
- inaccurate transcription of data
- misreading replies and
- keying errors when coding data into a data base
or spread sheet for analysis
The best
strategy is to try to solve problems
in the data before tabulating and analyzing responses.
