✅ Option b — Cumulative frequency
All Options:
- AClass interval
- BCumulative frequency
- CFrequency density
- DRelative frequency
Detailed Solution & Explanation
A cumulative frequency curve, also known as an Ogive, is used to visualize cumulative frequency distributions. In any graphical representation, we plot the independent/grouping variable on the horizontal axis (X-axis) and the dependent/counting variable on the vertical axis (Y-axis).
For a cumulative frequency curve:
- The **horizontal axis (X-axis)** represents the class boundaries (upper boundaries for a 'less than' ogive, and lower boundaries for a 'more than' ogive).
- The **vertical axis (Y-axis)** represents the corresponding **cumulative frequencies** (either 'less than' or 'more than' cumulative totals).
Therefore, on the Y-axis, we represent cumulative frequency. This matches Option B.
Hence, **Option B** is the correct answer.
