Median Class
What is it?
Find n/2 in the CF column. That class contains the median. Interpolation splits the class width in proportion to how far CF still needs to go.
In simple words
- Find n/2 in the CF column.
- CF crosses n/2
- median class at n/2
- mode = tallest class
Important terms
Median Class: Find n/2 in the CF column. That class contains the median. Interpolation splits the class width in proportion to how far CF still needs to go.
What you should learn
- Define and explain median class.
- Apply median class to a focused FBISE question.
- Check the answer for correct terms, evidence, working, and units.
Examples
- CF crosses n/2
- median class at n/2
- mode = tallest class
CORE UNDERSTANDING
Find n/2 in the CF column. That class contains the median. Interpolation splits the class width in proportion to how far CF still needs to go.
EXAM APPLICATION
State the correct term, connect it to the chapter rule or evidence, and use a clear example or calculation.
Recommended for Class 10
Full school-level explanation
