* Clearly define a target population that you can reach in your survey

* Clearly discuss your sampling plan: How will you obtain a
  representative sample from the the target population you defined?
  This should involve:

  – Clearly define a sampling frame: a list of persons in the target
    population from which you can draw a random sample. Acceptable
    frames include:

    (a) list of email addresses from which you can draw an SRS without
        replacement;

    (b) set of phone numbers or prefixes that you can use for
        random-digit dialling (this is again an SRS without
        replacement);

    (c) list or map of blocks, addresses, or similar geographic
        information you can use to randomly select houses or
        businesses to approach; etc.

    There are very few cases where a non-random sample with no clearly
    defined frame (e.g. man-on-the-street interviews) is
    acceptable. For man-on-the-street interviews, careful design of
    times/dates/locations, and method of approach people "on the
    street" (or on-campus, etc.) will be needed.

  – Clearly discuss how you will use the sampling frame to obtain a
    representative sample.
 
  – Clearly discuss how you will deal with nonresponse:
 
    o What will you do about reminding or following-up nonresponders?

    o If you suspect your sample is not representative of the target
      population, what adjustments do you anticipate making?
