Correct Answer Explanation
In Inclusive Class Intervals, values equal to both the lower and upper limits of a class are included in the frequency of that same class.
Inclusive Example (for marks 0–100):
- 0–10, 11–20, 21–30, ..., 91–100
- Here, both 0 and 10 belong to the class 0–10.
Key Points:
- Inclusive method is used very often for continuous variables.
- When classes are formed using the inclusive method, there may be a 'gap' or discontinuity between the upper limit of one class and the lower limit of the next.
- This gap requires an adjustment to restore continuity.
