We also looked at how ordinal data types can overlap with the discrete data types. What type of plot is suitable for which category of data was also discussed along with various types of test that can be applied on specific data type and other tests that uses all types of data.

An explanation of : interval; ordinal; ordered nominal; nominal; dichotomous; categorical data should not be treated as discrete data for statistical analysis.

Introduced some non-parametric statistical tests for analyzing ordinal data, e.g. Mood’s median test and the Kruskal-Wallis H test. Statistical tests say whether they change, but descriptions on distibutions tell you in what direction they change. Ordinal median. The median, the value or quantity lying at the midpoint of a frequency distribution, is the appropriate central tendency measure for ordinal variables.

Ordinal data is a statistical type of quantitative data in which variables exist in naturally occurring ordered categories. The distance between two categories is not established using ordinal data. In statistics, a group of ordinal numbers indicates ordinal data and a group of ordinal data are represented using an ordinal scale.

Abstract. Ordinal data are the most frequently encountered type of data in the social sciences. One common method is to assign scores to the data, convert them into interval data, and further perform statistical analysis.

What are levels of measurement in statistics? Nominal data; Ordinal data; Interval data; Ratio data; Why does this matter? It is argued that ordinal statistical methods are often more appropriate than their more common counterparts for three types of reasons: Conclusions from them A trauma patient with a score of 8 is considered more unstable than a trauma patient whose GCS is 14. Related Content. Nonparametric Statistical Analysis Ordinal variables have at least three categories and the categories have a natural order. For example, first, second, and third in a race are ordinal data. Multilevel proportional odds models offer the most flexibility of the suggestions given here and can be implemented using a range of general statistical software or Ordinal data is data which is placed into some kind of order by their position on the scale.

2013-02-13 Ordinal scale data can be in specific order; Unlike with nominal data, the assigned numbers are not arbitrary; This type of data scale does not allow for the calculation of an average or mean since the magnitude of difference between each assigned number is not the same. Because this is ordinal data, the assumptions that the data follow a normal distribution will be violated. Given that the assumption of normality is violated, a typical paired t-test in this situation would at best lack sensitivity, and at worst provide spurious estimates.
