Detailed Solution & Explanation
An ogive, also known as a cumulative frequency curve, is a graphical representation of a cumulative frequency distribution.
- A **Less than Ogive** is constructed by plotting the upper boundaries of class intervals on the x-axis and their corresponding 'less than' cumulative frequencies on the y-axis.
- The value on the y-axis for any point on a 'less than' ogive directly represents the total count (frequency) of data points that are less than or equal to (i.e., falling below) the corresponding x-value.
Let's analyze the options:
- Option A is represented by a frequency polygon or histogram.
- Option C is represented by a cumulative relative frequency curve (not a standard ogive, which plots raw frequency counts).
- Option D is represented by a scatter diagram.
Thus, a standard ogive represents the number of data points falling below a specific value. This corresponds to Option B.
Hence, **Option B** is the correct answer.
