Scales of measurement in research and statistics are the different ways in which variables are defined and grouped into different categories.
Likert scale questionnaires make complex opinion simple to understand. Keep reading to improve your surveys—and get better research data. A Likert scale is a question which is a five-point or seven-point scale. All Likert scales also include a mid-point e. It was developed in by the social psychologist Rensis Likert.

Such survey instruments can be used in many types of research, from case study, to cross-sectional survey, to experiment. They should also be able to use this information to interpret and critically analyze research reports that appear in professional journals and other publications. Respondents were required to rate using their experience how all factors affects labour productivity. A systematic review of literature to identify measures of health care research significance or importance suggested 6 areas of consideration: research activity, scientific production and impact, collaboration, dissemination, industrial production, and health services impact. However, theoretical relevance is only a part of measurement insofar as it leads to the identification of key variables to be considered; theoretical relevance not be addressed in this paper.
People often throw around the terms 'objective' and 'subjective' when talking about the results of a research study. These terms are frequently equated with the statistical terms 'quantitative' and 'qualitative'. The analogy is false, and this misunderstanding can have consequences for the interpretations and conclusions of usability tests. Comment, share or save this article. The terms 'quantitative' and 'qualitative' refer to kinds of data. The definitions of these terms are uncontroversial and can be found in any standard statistics text book. So body weights reported by a group of students, or a collection of IQ scores, or a list of task durations in seconds, or Likert scale category responses, or magnitude rating scale responses, are quantitative data.
A questionnaire is a research instrument consisting of a series of questions for the purpose of gathering information from respondents. Questionnaires can be thought of as a kind of written interview. They can be carried out face to face, by telephone, computer or post. Questionnaires provide a relatively cheap, quick and efficient way of obtaining large amounts of information from a large sample of people. Data can be collected relatively quickly because the researcher would not need to be present when the questionnaires were completed. This is useful for large populations when interviews would be impractical. However, a problem with questionnaires is that respondents may lie due to social desirability.
