We see that p-value = .145, and so there is no statistical difference between the parties regarding their satisfaction with the economy. If a significant result had been detected, then follow-up testing could be done using the One-Factor ANOVA data analysis tool.

In our enhanced ordinal regression guide, we show you: (a) how to create these dummy variables using SPSS Statistics; (b) how to test for multicollinearity using SPSS Statistics; (c) some of the things you will need to consider when interpreting your data; and (d) an option to continue with your analysis if your data fails to meet this assumption. THERE ARE FIVE MAIN STEPS IN HYPOTHESIS TESTING: Step 1) State your hypothesis as a Null (Ho) and Alternate (Ha) hypothesis. Step 2) Choose a significance level (also called alpha or α). Step 3) Collect data in a way designed to test the hypothesis.

Ordinal data are the most frequently encountered type of data in the social sciences. One common method is to assign scores to the data, convert them into interval data, and further perform statistical analysis. The Spearman rank correlation test does not carry any assumptions about the distribution of the data and is the appropriate correlation analysis when the variables are measured on a scale that is at least ordinal.
