It is quite common to add Likert items, even though this (as both WHuber and Sal have noted) requires that we are treating them as interval data. Instead of (or additional to) creating a table or a visualisation of the data, some statistical measures can provide a description of the sample data. An ordinal scale is a type of categorical variable where the categories have a natural order. Both interval and ratio level data. An ordinal scale variable is one in which there is a natural, meaningful way to order the different possibilities, but you can’t do anything else. interval censored and possibly 0-truncated (you should clarify what's going on with 0). Data can be classified as being on one of four scales: nominal, ordinal, interval or ratio. Nominal scale is used to name variables and Ordinal scale provides information about the order of the variables. Upon importing the data for any variable into the SPSS input file, it takes it as a scale variable by default since the data essentially contains. A linear regression tests the changes in the mean of the dependent variable by. Usually your data could be analyzed in multiple ways, each of which could yield legitimate answers. Mendefinisikan Variabel Baru dengan Variable View pada SPSS. The scale of measurement, also known as the level of measurement, describes the accuracy level that may be achieved while recording data. These assumptions are typically violated in the case of variables measured using ordinal rating scales (Timmerman & Lorenzo-Seva, 2011). Categorical variables take 2 forms--nominal and ordinal variables. $egingroup$ @ttnphns This is done all the time is areas like psychological research (but much more widely than that); that's after all exactly what a Likert scale is - a sum of items from ordinal items to produce a composite scale.

Various procedures like hypothesis testing, require that your data is collected with specific measurement levels. Nominal and Ordinal are, predictably, for nominal and ordinal variables. This is what distinguishes ordinal from nominal scales. g. Knowing the scale of measurement for a variable is an important aspect in choosing the right statistical analysis. “Nominal” scales could simply be called “labels. 3. Interval data can be discrete with whole numbers like 8 degrees, 4 years, 2 months, etc. For example, our satisfaction ordering makes it meaningful to assert that one person is more satisfied than another with their microwave ovens.
