Lower Limit Excluded Convention
In the exclusive form of class intervals, if values such as 10, 30 are put into classes '0 to 10' and '20 to 30' respectively, this is called the case of:
- Upper limit excluded
- Lower limit excluded — Correct Answer
- Inclusive method
- Open-ended class
Correct Answer Explanation
When values like 10 are put into '0 to 10' (not '10 to 20'), this is the 'Lower Limit Excluded' case.
Two Conventions in Exclusive Intervals:
- Lower Limit Excluded: Value 10 → goes into class 0–10 (upper limit = 10 is used). The lower limit of the next class is excluded.
- Upper Limit Excluded: Value 10 → goes into class 10–20 (lower limit = 10 is included). The upper limit is excluded from its class.
Key Point:
We must decide in advance which convention to use and apply it consistently throughout the distribution.
