Types of categorical variables include: Ordinal: represent data with an order (e.g. rankings). Nominal: represent group names (e.g. brands or species names). Binary: represent data with a yes/no or 1/0 outcome (e.g. win or lose). Choose the test that fits the types of predictor ...

(five) Kappa consistency coefficient (K coefficient of agreement; K) 1. X variables: categorical variables 2. Y variables: categorical variables The 3. formula: the Kappa consistency coefficient is the ratio of the percentage of the actual evaluation of the raters to the percentage of the maximu...
Less Common Types of Variables Active Variable: a variable that is manipulated by the researcher. Antecedent Variable: a variable that comes before the independent variable. Attribute variable: another name for a categorical variable (in statistical software) or a variable that isn’t manipulated (in...

We propose a method to map uncertainty zone of interpolated categorical variable. We transform categorical variable types into indicator functions for interpolation. Interpolation variance (InV) can be used to map the uncertainty zone. InV is a component of total variance, as measured by coefficient ...
Purpose To find out whether the association between two categorical variables are statistically significant Null Hypothesis There is no association between two variables Prior to using the chi square test, there are certain requirements that must be met. The data must be in the form of frequen...
The independent variables should not be correlated with each other i.e.no multi collinearity. However, we have the options to include interaction effects of categorical variables in the analysis and in the model. If the values of dependent variable is ordinal, then it is called asOrdinal logisti...
