I am taking an online statistics class and I am lost: Can someone help me?

What measurement scale (nominal, ordinal, interval or ratio) would you use for:

a) Absences from school
b) Physical Education grade
c) Math score on a standardized test
d) Writing score on a standardized test
e) Reading score on a standardized test

Thanks :D You will make my day if you can help!
 
Thanks...but more is needed

I have read all the definitions but none seem to give me a clear answer for these areas. I need to get them all right as I am not doing well in the course and need all the help I can get! :roll:
 
the standardized tests are probably interval measures. The idea is that the test is designed in such a way that the distance between two different results can always be determined. So if you got say a 120/150 and your friend got a 110/150. They would be able to determine, the number of people who would normally fall between your two scores.

the physical education test is ordinal as you are usually ranked against the others in the class from best to last.

And the Absences would be a ratio (absence vs attendance) or absence vs (total classes)
