Question

Assertion (A): In a frequency polygon, the frequency of a class interval is plotted against the upper limit of the class.

Reason (R): A frequency polygon is a closed figure, its end points are joined to the x-axis.

Options

• Both A and R are true and R is the correct reason for A.

• Both A and R are true but R is the incorrect reason for A.

• A is true but R is false.

• A is false but R is true.

Answer 1

A is false but R is true.

Explanation:

In a frequency polygon, frequencies are plotted against class marks, not upper limits, so the assertion is false. However, the reasoning is true since a frequency polygon is a closed figure whose end points are linked to the x-axis to complete the shape.
