Regression

I have interval and ordinal data and I want to know if the interval data makes a difference in the way ordinal data is presented.

Below is a survey of teachers. On the left most column is the number of students the teacher mentored in the past year. On the right columns are ordinal rankings of students that the teachers filled out. I want to know if seeing more student (i.e. 10 to 16 students) influences how teachers answer the rating of students.

What type of statistical analysis would I do and how would I set it up in SPSS? Would I categorize the numbers of students seen into small and large first? Would I find the means of the ordinal data? What do I do?

number of students seen scale 1-6 on attention skills scale 1-6 on com skills scale 1-6 on writing skills scale 1-6 on listening skills
