There are several steps with questionnaires that have to be followed, in
sequence:
Step 1 involves deciding to whom they should be sent. Because questionnaires
involve requesting persons outside the institution or organization to devote
time to replying, it is essential that only the right persons be approached
and that the questionnaire be kept short as possible. Defining the “correct”
respondents is an essential step.
First, define the respondents. Determine to whom the questionnaires should
be sent from the performance indicators of the respective outcomes. If, for
example, the indicator is the use of recommended data collection techniques,
the target audience would be officials who do this in research stations.
In interviews, an option exists to send the questionnaire to a random sample
of persons in the population from which information is to be requested.
Whether this should be used depends on: (a) the size of the population and
(b) the likelihood that there will be a high rate of return. If there is a
low rate of return (a large percentage of questionnaires are not returned) –
as is usually the case ? the reliability of the sample cannot be determined.
To avoid this problem it might be useful to make the decision about the
means of transmission at this point . If the questionnaire is to be sent to
everyone who should be requested for information, you can skip the material
on sampling. If not, you should review the material on sampling under the
material on surveys.
The remaining steps, which will be dealt with in detail, are:
How will they be sent?
What will they ask?
How can the responses be interpreted?
