In most cases, it opted for a written survey. The advantages of this form of survey diminishing that little effort and cost required to get a large group of respondents. Many have also used closed questions, so the analysis of the responses can happen quickly. A disadvantage of this form of inquiry and questioning is that no additional explanation can be given or additional information may be requested.

For a good survey, a number of very important aspects. The most important is objectivity. The results of a survey you need to have the information you get from actually the information to which the views of respondents reflects. It is therefore important that respondents are not influenced when filling out the survey. Therefore provide a survey that anyone can be completed. Thus, the same conditions for all respondents. Provide the survey of a clear and bright letter you explain what the survey means and what it meant. Explain clearly how the survey should be completed. This will allow more people complete the survey and ask if the instructions are completed, the information you get from the survey even more valuable. Note parallel, the length of your survey. If it lasts longer than 45 minutes to answer the questions you should be very motivated to complete the survey. Moreover, 45 minutes for an Internet survey quite long. Rather it depends upon the interest of respondents to the topic. We recommend a forum / website: 5 minutes max. Email among a large group (such as all students of one year or a customer base): max 10 minutes. Email among a select group (eg relationships): 30 minutes max.

It is also important to think about the order of your questions. Sensitive questions can be such a better place somewhat later in the survey, so respondents have 'used' to fill. Note also the spelling. Spelling and grammar are important in the perception of respondents about the professionalism and competence of the interviewer.
