In the analysis of an infinite series, the sequence of partial sums are can be classified as either convergent of divergent. The series can be classified as a convergent sequence when a limit exists and is finite. The opposite is true, where the sequence of partial sums can be classified as a divergent sequence when the limit doesn't exist or is positive of negative infinity.
In ordinal measurement scale the order of values or variables are very important. Just as in the case above, the rating from 1-3 is according to the order of it's importance.
