86.115—How should I administer the survey?
Use a consultant or university specializing in administration of such surveys. Use sample sizes large enough to achieve statistical accuracy so the estimate is within plus or minus 10 percent of the true number.
(a)
You may use a telephone, mail, or other type of survey for a sample population of boaters within the State. Costs for telephone and mail surveys are roughly similar. However, response rates for mail surveys are generally lower.
(b)
For boat access providers, we prefer that you survey all State agency and non-State providers, but you may survey a sample population.
(c)
You may develop your own methodology to collect data, which may include telephone, mail, fax, or other inventory means. We do not expect you to use automated, electronic, mechanical, or similar means of information collection.
(d)
Data collected are unique to each respondent. Data collection should use standard survey method criteria to gather information from each respondent.
