Question

Which one of the following measures is determined only after the construction of cumulative frequency distribution?

Options

• Mean

• Median

• Mode

• None of these

Answer 1

Median

Explanation:

The median is found by locating the point where the cumulative frequency reaches `N/2` (or by the intersection of the ‘less than’ and ‘greater than’ ogives), so you must construct the cumulative frequency distribution (ogive) to identify the median class/value. Mean and mode can be obtained directly from frequencies/class marks (they do not require the cumulative distribution).
