Survey approach has the following strengths and weaknesses:
Strengths:
Surveys are easy [link widoczny dla zalogowanych] to administer.
Surveys are simple to score and code.
Surveys determine the values and relations of variables and constructs.
Surveys can be reused easily, and [link widoczny dla zalogowanych] provide an objective way of comparing responses over different groups, times, and places.
Weaknesses:
Surveys are just a snapshot of behavior at one place and time.
They do not provide [link widoczny dla zalogowanych] as rich or "thick" description of a situation as a case study. They do not provide as [link widoczny dla zalogowanych] strong evidence for causality between surveyed constructs as a [link widoczny dla zalogowanych] well designed experiment.
The survey activities can be considered with the [link widoczny dla zalogowanych] need of a detailed check list to be followed in the development and use of necessary survey instruments.
Among these significant steps are:
-Determination of the unit of analysis (e.g., the individual, group, or organization)
-Pre-testing and use of pilot data
-Assessment of reliability
-Random [link widoczny dla zalogowanych] sampling from a defined sample frame.
-Determination of statistical power of the final analysis.
