Years in which a war was started

Choose the correct answer below.

1. The nominal level of measurement is most appropriate because the data cannot be ordered.
2. The ordinal level of measurement is most appropriate because the data can be ordered, but differences (obtained by subtraction) cannot be found or are meaningless.
3. The ratio level of measurement is most appropriate because the data can be ordered,differences (obtained by subtraction) can be found and are meaningful, and there is a natural starting point.
4. The interval level of measurement is most appropriate because the data can be ordered, differencescan be found and are meaningful, and there is no natural starting zero
