The Questionnaire is an instrument of research. This instrument is used, a preferred mode, the development of research in the field of social science is a technique widely applied in research of a qualitative nature. Nevertheless, construction, implementation and tabulation have a high scientific and objective. Developing a valid questionnaire is not an easy question, entails a series of control variables.
A questionnaire survey is a real project: it implies clear objectives, a rigorous methodology and organization, careful planning and, of course, sometimes significant investment of time and money. If the investigation can provide useful insights and provide a basis for choices, it also results in an interaction with the respondents (customers, employees ...). The approach may have some consequences in terms of communication and cause reactions on the part of those concerned with the subject of the investigation. Thus, a survey of customer satisfaction can be seen internally as a critical, questioning, and a sign of defiance against staff. Conversely, the same survey can be viewed very positively by customers, happy to see that we are interested in their opinions. A good awareness of issues and possible consequences is essential before addressing the technical phases of the investigation process (Dillman & Hill, 2000).
The idea of ??a systematic study population is a primary objective of the initial investigations. The studies, therefore, are usually based on a standardized questionnaire to collect reliable information on a wide range of respondents. Reliability, in this context refers to the notion that the same applies to the corresponding means of samples to produce consistent results. But reliability is not enough. It is possible that a query of a wrong operation consistent with the building. Add to the period of validity is a second criterion is the quality and refers to the idea that the questionnaires must be given not only compatible with the measurements of the neutral and the exact behavior of people, attitudes, and so on. Validity refers to whether an investigation is to measure what the designer's view, to measure.
In addition, the structure of the query, the specific field of a critical variable in the construction of existing instrument. In particular, well-structured questionnaires, using the language and terminology that is designed to avoid bias. These biases can become a language that is likely to be more of the respondents than others (for example, terms that are more likely to understand some of the ethnic groups or training cohort) or stimulating the defendants, who are interested in or more information about the science and technology in the first place. All the formatting, which supplies these possible biases introduced systematic measurement error, because it does not produce the same force in all subgroups of the population. Reliability and validity of a number of factors associated with the study process. But two factors are particularly important for the construction of the questionnaire: the overall structure of the questionnaire and were given specific questions (Alreck & Settle, 2003).
