Measurement Scales - Assignment Example

Measurement Scales February 6 Nominal- A categorical variable that is used for mutual, exclusive, though not ordered categories (What is the difference…2013). Values can be assigned a code in the form of a number2. Ordinal- A variable where the order matters but not the difference between variables- you do not need to know the precise difference between the items only the order in which they occur (What is the difference…2013).3. Interval- A variable where the difference between two items is meaningful (What is the difference…2013).

Equal distance between variables4. Ratio- A value that has all of the properties of an interval variable but also has a clear definition of 0.0; you would have a ratio variable if you were describing height or weight (What is the difference…2013).Type of DataExampleStatistical procedureNominalWhiteAfrican AmericanAsianHispanic-Respondent’s Response rate in literature reviews (Badger, F., & Werrett, 2005)Chi-Square Test for Goodness of Fit(Charles Dennis Hale, 2012)Frequencies, percentages modesOrdinalGrades, Pain scaleConfidence and Preference rating Scales,Frequencies,Mode,Median,PercentilesIntervalThoughts, behaviors, feelings on a scale- Likert scale, Temp C or FQuantitative measuring of character, personality and attitude(Boone, and Boone, 2012)RatioAge, WeightProtein ratio calculationStatistics could be used in my own evidenced based practice several ways.

Ordinal scales are more precise and can be used to measure such as in the case of transplant recipients; they are given a number which identifies their order on the list based on items such as symptoms and severity, type and cross matching, and the timing of the request. When there is availability the next person eligible on the list is called. Nominal scales can be used for race, gender, and identification of patients. Interval scales are used for items such as F temperature where the measurement where the measurement if ordered from high to low.

The ratio scale is the most precise measurement and can be used for items such as the weight scale. ReferencesBadger, F., & Werrett, J. (2005). Room for improvement?
