I am currently finishing my bachelors thesis and have a couple of questions regarding correlation in spss. I have a questionnaire that generates metric data, nominal data and ordinal data. I used Spearman to correlate all the ordinal datasets and I am quite comfortable that this is fine. Now comes the hard part: How do I correlate the metric data with my ordinal data? Metric data consists of age and kilomenters driven per year. Ordinal data consists of "agree", "agree partly", "neither agree nor disagree", "disagree partly", "disagree". Is it possible to turn my metric data into ordinal data with 3 values (e.g. "young", "middle aged", "old" and then use spearmen to correlate it to the other ordinal data with spearman?
Additionally I would like to ask how I can correlate the ordinal data with the nominal data (being "yes" and "no")? Unfortunately I don't have any idea on how to do that.
