Question

Which of the following graph is also called Ogive?

• A. Histogram
• B. Climograph
• C. Frequency polygon
• D. Cumulative frequency curve

Hint:

Remember these statistical graphs: \[ \boxed{ \begin{aligned} \text{Histogram} &\rightarrow \text{Frequency Distribution}, \text{Frequency Polygon} &\rightarrow \text{Line Graph of Frequencies}, \text{Ogive} &\rightarrow \text{Cumulative Frequency Curve}, \text{Climograph} &\rightarrow \text{Climate Representation}. \end{aligned} } \] Mnemonic: “Ogive = Overall (Cumulative) Frequency.”

Answer 1

The Correct Option is D

Concept: An Ogive is the graphical representation of cumulative frequencies. It is also known as the cumulative frequency curve and is used to determine the median, quartiles, percentiles, and other positional measures.

Step 1: Recall the definition of an Ogive. An Ogive is a \[ \boxed{\text{Cumulative Frequency Curve}} \]

Step 2: Eliminate the incorrect options. \[ \begin{aligned} A. &\ \text{Histogram} \rightarrow \text{Represents frequency distribution using bars.} B. &\ \text{Climograph} \rightarrow \text{Represents climate data (temperature and rainfall).} C. &\ \text{Frequency Polygon} \rightarrow \text{Connects class midpoints.} D. &\ \text{Cumulative Frequency Curve} \rightarrow \text{Also called an Ogive.}\checkmark \end{aligned} \] Hence, \[ \boxed{\text{(D)}} \]
