MCQ
One of the sides of a frequency polygon is:
- ANeither of the coordinate axes.
- ✓The $x$-axis.
- CEither of the coordinate axes.
- DThe $y$-axis.
✓
Answer
Correct option: B.
The $x$-axis.
In frequency polygon $x$-axis repesents data value whereas $y$-axis is used represent the frequencies of the data.
We include one class below lowest value and one class above highest value with zero frequencies.
The graph touches the $x$-axis at these points.
So, one sides of the frequency polygon is $x$-axis.
