In constructing a frequency distribution with exclusive class intervals, the upper limit of one class is:
A. Ignored in frequency counting
B. Excluded from that class and included in the next higher class
C. Always equal to the lower limit of the next class
D. Included in that class
Answer: Option B
Solution (By JKSSB Mock Tests)
In exclusive class intervals, the upper limit is not included in the class; observations equal to the upper limit are counted in the next higher class to avoid overlap and ensure mutual exclusivity.
