Data Inclusion in Range
Range includes-
- 50% of the items
- 100% of the items — Correct Answer
- 25% of the items
- 0% of the items
Explanation:
Correct Answer: 100% of the items
The Range includes 100% of the items in a dataset because every observation in the data falls between (or at) the minimum and maximum values that define the range.
Range — Key Facts
- Definition: The difference between the largest and smallest values in a dataset
- Coverage: All data points (100%) lie within the range by definition
- Calculated from: Only 2 observations (max and min) — hence most affected by extreme values
- Most affected by: Extreme values (outliers)
Data Coverage — Comparison of Measures
| Measure | Data Points Used | Coverage of Data |
|---|---|---|
| Range | Only 2 (max & min) | 100% fall within range |
| Quartile Deviation | Q1 & Q3 | Middle 50% |
| Mean Deviation / S.D. | All observations | Uses all data in calculation |
Why Other Options Are Wrong
- 50% → applies to Quartile Deviation (interquartile range), not Range
- 25% → no standard measure covers exactly 25% of items
- 0% → logically impossible; all items are within range by definition
