Sorry, I don't understand what this means. All rights reserved. In addition to categorizing the variables in a hierarchical form, the interval scale of measurement labels the variables with equally spaced intervals. It sounds like "accuracy" would depend on "preference". Understanding the difference between nominal VS ordinal scale is crucial in data analysis, as it determines the appropriate statistical tests and the interpretation level that can be applied to the data. It simply divides the variables into a data set into different groups, depending upon their names. Nominal data is often referred to as "categorical data" because it assigns a category or label to each value in the data set. As for the code to do the tests, try this: Firstly you need to make sure you have the right packages installed. Use MathJax to format equations.

Does anyone know what the best way to do that would be? number of dependent variables (sometimes referred to as outcome variables), the nominal variable Essentially, if a high count in one category is related to a high or low count in another category of another variable. These errors are unobservable, since we usually do not know the true values, but we can estimate them with residuals, the deviation of the observed values from the model-predicted values.
