Ex.) making a note of how the toy is red, or how big it is. Nominal Scale - answer - When the data for a variable consists of labels or names used to identify attributes of elements. Ordinal Scale - answer - The data exhibits the properties of nominal data and in addition, the order of the rank of the data is meaningful. ex.) In the toy example, you can measure the toys on an ordinal scale by assigning them a meaningful order or ranking based on a specific characteristic. Let's say you want to rank the toys based on their size. 1 would be the smallest while 3 would be the Biggest. 1. Small 2. Medium 3. Large.
