SHS investigation development is considered from the geographical and historical viewpoint. 3 stages are described. Within Stage 1 the work was carried out in the Department of the Institute of Chemical Physics in Chernogolovka where the scientific discovery had been made. At Stage 2 the interest to SHS arose in different cities and towns of the former USSR. Within Stage 3 SHS entered the international scene. Now SHS processes and products are being studied in more than 50 countries.
Abstract
A survey is one of the most common methods in health sciences research.
As in this case, choosing a suitable study design depends on the research question, so
also survey research questions also decide methods. The decision of application of
scale of measurement depends on the nature of the observations, which could be
numerical, nominal, or ordinal. If research develops his/her new survey instrument
(survey questionnaire), its validity & reliability requires other important treatments.
This forms the subject of discussion in this chapter.
Keywords:
Confidentiality, Likert scale, Reliability, Scale of measurement, Validity.
