The Correct Answer and Explanation is:
Here are the correct answers for each type of data based on the scale of measurement:
7. General Weighted Average (GWA)
Answer: Interval
Explanation:
The General Weighted Average (GWA) is considered interval data. It is numerical and has meaningful differences between values, such as the difference between a GWA of 1.5 and 2.5. However, it does not have a true zero point. A GWA of 0 does not mean an absence of academic performance, and ratios cannot be meaningfully interpreted (e.g., a GWA of 2.0 is not “twice” as poor as a GWA of 1.0). Therefore, it is classified under the interval scale.
8. Number of Student Dropouts
Answer: Ratio
Explanation:
The number of student dropouts is a ratio variable. It is numerical, and the differences between values are meaningful. Most importantly, it has a true zero—zero dropouts means there were no students who left, and you can say, for example, that 10 dropouts is twice as many as 5 dropouts. These features make this a ratio level of measurement.
9. Family Name
Answer: Nominal
Explanation:
Family names are nominal data. They are used as labels or categories and do not have any numerical or ranked meaning. You cannot say one surname is higher or lower than another, and arithmetic operations do not apply. They simply identify or distinguish individuals or groups.
10. Teacher Evaluation
Answer: Ordinal
Explanation:
Teacher evaluations are commonly ordinal. Evaluations often use rating scales like “poor,” “fair,” “good,” and “excellent.” These categories have a meaningful order, but the intervals between them are not equal. For example, the difference between “fair” and “good” is not necessarily the same as between “good” and “excellent.” Therefore, this type of data is best classified as ordinal.
