2. Describe the four types of measurement scales.
The
four scales are nominal, ordinal, interval, and ratio.
- The nominal scale separates individuals or items into categories -- e.g. seniors and juniors.
- The ordinal scale helps to rank order the separated items.
- The interval scale helps to determine the extent to which the items are different from each other. In other words, is the difference between item 1 and 2 the same as the difference between 4 and 5?
- The ratio scale helps to determine the proportion of differences among items since it has an absolute zero origin, and is the most powerful of the four scales.
