Preliminary Considerations for Questionnaire
... This is a special type of purposive sample. Here the researcher takes explicit steps to obtain a sample that is similar to the population on some “pre-specified” controlled characteristics. e.g., a interviewer may be instructed to select half of the interviewees from people 30 years of age and older ...

Although the public may not understand the statistical meaning of a margin of error, it can be translated into a percentage that is meaningful to the general population. Confidence limits can also ...
