Classify the following as an example of a nominal, ordinal, interval, or ratio level of measurement, and state why it represents this level: eye color of family members
Figure out the difference between all these classifications and look at different peoples eye color in your family. Use your best judgement
The different levels of measurement depend on how precise they are. Nominal is a name only - a category/quality Ordinal is order, so there is a difference in bigger vs. smaller. Interval has equal spacing between measurements, so you can measure multiples of whole numbers. Ratio measures are the most precise and include an 'absolute zero.' Ratios can take on any whole or fractional number. Each higher level includes all the qualities of all the lower levels below it.
