Univariate (statistics) Univariate data types[edit] Some univariate data consists of numbers (such as the height of 65 inches or the weight of 100 pounds), while others are nonnumerical (such as eye colors of brown or blue). Generally, the terms categorical univariate data and numerical univariate data are used to distinguish between these types. Categorical univariate data[edit] Numerical univariate data[edit] Data analysis and applications [edit] Like other forms of statistics, it can be inferential or descriptive.
The key fact is that only one variable is involved. Univariate analysis can yield misleading results in cases in which multivariate analysis is more appropriate. Measures of central tendency[edit] Measures of variability[edit] Descriptive methods[edit] For interval and ratio level data, further descriptors include the variable's skewness and kurtosis. Inferential methods[edit] Graphical methods[edit] The most frequently used graphical illustrations for univariate data are: Frequency distribution tables[edit]
