B Correct answer
Explanation

A frequency polygon is constructed by joining the midpoints of the tops of histogram bars, while a frequency curve is a smoothed version of a frequency polygon. They are distinct concepts in statistics.

  1. True

  2. False
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

This is identical to question 394724. An ogive is the curve obtained by plotting cumulative frequencies against class boundaries. The statement 'A curve obtained by plotting cumulative frequencies is called an Ogive' is the standard definition in statistics.
