Nominal scale level- Is qualitative (categorical). This would be categories, names, labels and favorite foods. There is no order and makes no sense to put
Ordinal scale level- Is similar to nominal scale, but can be ordered based on a scale. Question like "excellent, good, satisfactory, and unsatisfactory", top 5 parks, or rankings in a race would be an Ordinal scale.
Interval scale level- Interval Scale is order matters and there is a difference between the data. Temperature is the most common example. The difference between weather means something, but 0 is not the absolute lowest it can be.
Ratio scale level- Ratio is like interval where 0 is the lowest point available. In this case the difference matters and so does multiplying. Test scores would be and example of this
