Correct Answer

✅ Option a — Less than Cumulative frequencies on the vertical axis

All Options:

  • ALess than Cumulative frequencies on the vertical axis
  • BMore than Cumulative frequencies on the vertical axis
  • CHighest frequencies on vertical axis
  • DLowest frequencies on vertical axis

Detailed Solution & Explanation

An ogive is a graph showing the curve of a cumulative frequency distribution. To draw a **Less than Ogive**: 1. We first construct the 'less than' cumulative frequency table, which lists the number of observations that are less than or equal to the upper class boundaries of each class interval. 2. We plot the **upper class boundaries** on the horizontal axis (X-axis). 3. We plot the corresponding **'less than' cumulative frequencies** on the vertical axis (Y-axis). 4. We join the plotted points by a smooth freehand curve. Thus, a less than ogive curve is drawn by plotting the 'less than' cumulative frequencies on the vertical axis (Y-axis). This matches Option A. Hence, **Option A** is the correct answer.
