Analysing an ordinal and a scale variable
If you have an ordinal and a scale variable you might want to know if there is a relationship between the two. This can be done using the following steps:
1) Get an impression of the sample data by determining some measurements (means and standard deviations)
2) Visualise the sample data by using a split histogram or side-by-side box-plot.
3) Test if the relation might still be present in the population, and how strong this effect is by using Spearman's rho.
4) Write up the report.
For each of the described steps above a separate page is created. Let's begin with getting an impression from the data on the first page.
