Key Difference Between Exclusive and Inclusive Forms
The difference between the Exclusive class interval form and Inclusive class interval form for the same data can be seen in which key aspect?
- The total frequency changes between the two forms
- The class limits overlap in exclusive form but not in inclusive form
- There is a gap between classes in inclusive form; no gap in exclusive form — Correct Answer
- Exclusive form has more classes than inclusive form
Explanation:
Correct Answer Explanation
In inclusive form there is a gap between classes (e.g., 0–10, 11–20 — gap between 10 and 11). In exclusive form, there is no gap (0–10, 10–20 — continuous).
Key Comparison:
- Inclusive (0–10, 11–20): Gap between 10 and 11 → requires adjustment for continuous variables.
- Exclusive (0–10, 10–20): No gap → upper limit of one class = lower limit of next → maintains continuity.
- Total frequency is the same in both forms (same data, same n).
