REQUESTED ASSISTANCE - Would you please review the provided answer as well as the provided reason (detailed explanation / analysis) for the answer to the below data type question. Is the provided answer correct, and what improvements can be made to the provided reason (detailed explanation / analysis) for the answer?

The letter grades for this class goes from A, A-, B+, B, B-, ......... What scale this type of data belong to?

ANSWER: Ordinal REASON: Ordinal means in order, and an ordinal scale is a measurement that allocates an ordered value to variables based on their relative logical ranking with respect to one another in a given data set. For example, the time of day can be ordered in a successive sequence from start to finish: dawn, morning, noon, afternoon, evening, night. Ordinal scale measurements indicate a logical hierarchy among the variables and provides information on whether something being measured varies in degree, but does not specifically quantify the magnitude between successive ranks. For example, track runners are awarded 1st, 2nd, and 3rd place in track races, but if the individual track runner's finish times are unknown, then there is no means to quantify the interval between their successive places. As for question 3, the letter grades for a class ordered from A, A-, B+, B, B- is a type of hierarchical data that observes all of the above elements, which means it's classified as an ordinal scale.
