The test for trend, in which at least one of the variables is ordinal, is also outlined … Statistics review 8: Qualitative data - tests of association ordinal data) Predicting the value of one variable from the value of a predictor variable Continuous/ scale Any Simple Linear Regression Assessing the relationship between two categorical variables Categorical/ nominal Categorical/ nominal Chi-squared test Note: The table only shows the most common tests for simple analysis of data. Examples: The ordinal data tests are also four, namely; Wilcoxon signed-rank test, Friedman 2-way ANOVA, Wilcoxon rank-sum test and Kruskal-Wallis 1-way test.

Some techniques work with categorical data (i.e. nominal or ordinal data), while others work with numerical data (i.e. interval or ratio data) – and some work with a mix. While statistical software like SPSS or R might “let” you run the test with the wrong type of data, your results will be flawed at best , and meaningless at worst. Noting the number of patients in each group (100 each), however, I did read that with those numbers, even for ordinal integer data, parametric methods such as t-test with a Welch correction yield Abstract. Ordinal data are the most frequently encountered type of data in the social sciences.
