Answer: Option 4: Reliability, Validity, Sensitivity, Consistency

Step-by-step explanation:

The four attributes of a good measurement system are:

Option 4: Reliability, Validity, Sensitivity, Consistency

Here's what each of these attributes means:

1. **Reliability:** A good measurement system should yield consistent and reproducible results when measuring the same thing under the same conditions. In other words, it should produce reliable measurements that are not overly influenced by random errors.

2. **Validity:** The measurements should accurately and meaningfully represent the specific attribute or characteristic being measured. Validity ensures that the measurement system is measuring what it intends to measure.

3. **Sensitivity:** Sensitivity refers to the ability of the measurement system to detect and differentiate small variations or changes in the attribute being measured. A sensitive measurement system can identify even subtle differences.

4. **Consistency:** The measurements produced by the system should be consistent and stable over time. Consistency ensures that the same measurement system will yield similar results when used repeatedly under similar conditions.

Option 1 includes precision and accuracy, which are related to reliability and validity but does not include sensitivity and consistency, which are also important attributes of a good measurement system. Option 2 includes attributes like cost-effectiveness and subjectivity, which are not inherent attributes of the measurement system itself. Option 3 includes inaccuracy and ambiguity, which are not desirable attributes of a good measurement system.
