Final answer:
The ordinal scale is the measurement scale used to identify differences and their direction between individuals, without quantifying the magnitude of the difference.
Step-by-step explanation:
The type of measurement scale that enables a researcher to determine whether two individuals differ and the direction of the difference, but does not allow for the measurement of the magnitude of the difference, is the ordinal scale. An example of ordinal scale level data could be classifying high school soccer players by their athletic ability as superior, average, or above average. While you can tell who is more or less skilled, the exact difference in their abilities is not quantified.
