-------------------------------------------------------------------------------------------------------

The terms nominal, ordinal, interval, and ratio all describe levels of measurement. Knowing the level of measurement that you're using helps you interpret the data and decide what statistical tests and analyses to use.

In general, it is better to use higher levels of measurement than lower levels of measurement (although, sometimes you have to use low levels of measurement based on the data that you're collecting -- not all data can be put into every level of measurement). This is because, as you go up the hierarchy from nominal to ordinal to interval to ratio, each level has all of the information contained in the levels below, but also adds something new.
