Frequency tables containing interval/ratio-level data can include all of the same components as those containing ordinal-level data, though they often include class intervals in order to make. These are still widely used today as a way to describe the characteristics of a variable. Table 1 The statistical tests that could be used based on the type of data, i. This test is also known as: Chi-Square Test of Association. In this sense, the closest analogue to a "correlation" between a nominal explanatory variable and continuous response would be η, the square-root of η 2, which is the equivalent of the multiple correlation coefficient R for regression. Each of those levels gives you different amounts of analyzable information in SPSS. These assumptions are typically violated in the case of variables measured using ordinal rating scales (Timmerman & Lorenzo-Seva, 2011).
