For example, if you look at your research participants as they enter the room, decide whether each one is male or female, and type this information into a spreadsheet, you are engaged in nominal-level measurement. Or if you ask your participants to indicate which of several ethnicities they identify themselves with, you are again engaged in nominal-level measurement. When you know that a measure is nominal (like the one just described), then you know that the numerical values are just short codes for the longer names. Measurement refers to careful, deliberate observations of the real world and is the essence of empirical research. Validity refers to how accurately a method measures what it is intended to measure. Furthermore, it is important that the surveys and interviews are not extremely time-consuming (ideally within a 20-30 minute limit). Research measures include survey questions, interview questions, or constructed situations.

Adedokun (2003:57) asserts that data refers “to any fact, observation or facts relating to the subject of the study”. A nominal scale, as the name implies, is simply some placing of data into categories, without any order or structure. What is the goal of measurement in research A to refect both quanttatve and. High reliability is one indicator that a measurement is valid. If a method is not reliable, it probably isn’t valid. Introduction (cont. Most books on measurement present a statistical orientation or an orientation toward measurement theory. The paper must clearly describe the measurement context in which the research was carried out by undertaking a critical review of the state-of-the-art of the relevant body of knowledge in instrumentation and measurement and by showing how the research presented advances it; The letter accompanying the submission must describe clearly how the paper satisfies the above requirements. Ways To Measure Research Although young computer scientists are told that they need to produce research results, no exact requirements are specified. Suggested Citation:"2 Measurement in the Social Sciences. The instruments are used to measure or collect data on a variety of variables ranging from physical functioning to psychosocial wellbeing. Validity tells you how accurately a method measures something. Scaling is considered as the extension of measurement. 2011.

Although these approaches are valuable, Measurement 3. The book gives particular attention to measurement issues resulting from changes in nursing, health research, and the increased emphasis on and undertaking of interprofessional research and evaluation. Ordinal scale is the 2nd level of measurement that reports the ranking and ordering of the data without actually establishing the degree of variation between them. “Scaling” in Research. Historically, many measurement systems existed for the varied fields of human existence to facilitate comparisons in these fields. 5) evaluate the hypotheses . If research has high validity, that means it produces results that correspond to real properties, characteristics, and variations in the physical or social world. 3. • The measurement process begins with formulation of research problem or hypothesis. The research sample from the 2010-11 school year was drawn from five school districts representing a range of urban, ... measures featured built in access to manuals and allowed observers to navigate quickly to specific portions of the measure depending on what was occurring in the classroom at any given moment.

When constructing interviews and surveys, it is important that the questions directly relate to the research questions. Research Design & Scales of Measurement . A variable has one of four different levels of measurement: Nominal, Ordinal, Interval, or Ratio. Measurement is a cornerstone of trade, science, technology, and quantitative research in many disciplines. While some constructs in social science research, such as a person’s age, weight, or a firm’s size, may be easy to measure, other constructs, such as creativity, prejudice, or alienation, may be considerably harder to measure. Pages 204. In quantitative research, you have to consider the reliability and validity of your methods and measurements. Example 1: To … Definition: Scaling is the procedure of measuring and assigning the objects to the numbers according to the specified rules. Creswell (2005) also presented a concise history of quantitative research methodology by partitioning quantitative methods into these three domains.
