Paper on Scales of Measurement Measurement in analysis can take many forms, but in this case these come in the form of questionnaires. An incorrectly executed questionnaire may not be able to obtain the information the company is looking for. There are generally four categories that they fall into. At the categorical level, these include nominal, ordinal, interval, and ratio numbers. This author's essential goal is to explain with the utmost authority how these fit into the questionnaires. Attitude can play a role in the variables that make up these types of scales: from nominal to ratio. The general aptitude scale will involve measurement in the same aspect as measuring someone's temperature or measuring the distance between places. Nominal – In a nominal scale, items are assigned to mutually exclusive labeled categories, but there are no necessary relationships between the categories (Aakar, Kumar, & Giorno, 2007). In other words, there is no implicit spacing or ordering (Aakar, Kumar, & Day, 2007). If one entity is assigned the same number as another, they are considered identical with respect to a nominal variable (Aakar, Kumar, & Day, 2007). Well-known examples often used in questionnaires like this include: geographic location, marital status and sex (i.e. gender specification). The lowest level of measurement used from a statistical point of view, these are non-parametric groups. Since qualitative information is obtained from a nominal scale, only names are used. Some general examples of noun questions include: Race: Caucasian, African/American, Latino; Hair color: blonde, brown, red, black or gray. Another example would be the number of car dealerships within a given state and/or county.Ordin......middle of sheet......size size of this type. It is the researcher's job to ensure that the interviewee has the competence to make these proportional judgments, which means that interviewees must be allowed to practice before attempting real research questions (Aakar, Kumar, & Day, 2007). Measurement scales in research can play a significant role in determining data variables and how they fit into questionnaires to obtain the right kind of information. Nominal, Ordinal, Interval and Ratio are just a few examples of measurements that have been mentioned. Works Cited Aakar, D. A., Kumar, V., & Day, G. S. (2007). Marketing Research 9th Edition.
