I have one interval variable on a 1-25 point interval scale, i.e. placement test scores where 25 is the highest competence score (data not normally distributed), and six different ordinal variables on a 1-7 likert scale (where 7 is the highest score) in my data set. There are 12 participants (12 interval test scores) and 6 raters (each scored 6 different ordinal variables per participant).
Based on what I've read, I've decided to run the Spearman's correlation between the interval and each ordinal variable (i.e. six different correlation tests between the interval variable and each ordinal variable) in SPSS but would it be one-tailed? Or is there any other test I should run to test the level of agreement between the raters in my study?
Thank you for your time and consideration in reading this question!
