The primary difference between an ordinal level and inteval level variable is:
A. an ordinal level variable has a meaningful zero point while the inteval level variable has no zero point
B. an interval level variable has an assumed equal distance between values while an ordinal level only displays an odered list
C. an interval level variable and an ordinal level variable can be considered the same except that an interval level variable has a meaningful zero point
This solution goes through the difference of ordinal and interval level variables.
