Ogive Alternative Name

Ogive is also called:

Correct Answer Explanation

Ogive is also called cumulative frequency curve.

Key Points:

• There are two types: "less than" ogive and "more than" ogive.
• "Less than" ogive plots cumulative frequencies against upper class limits.
• "More than" ogive plots cumulative frequencies against lower class limits.
• The intersection of two ogives gives the median of the frequency distribution.
• "Less than" ogive is never decreasing and "more than" ogive is never increasing.

Why Other Options Are Wrong

• A. Frequency polygon: This joins midpoints of histogram tops, different from ogive.
• C. Frequency curve: This is a smooth freehand curve through frequency polygon points.
• D. Arithmetic line graph: This is a time series graph.
