The graph of successive points of a distribution joined by straight lines in statistical terminology is known as _________.

  1. frequency polygon

  2. frequency curve

  3. trend

  4. cumulative distribution curve
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

A frequency polygon is constructed by plotting the midpoints of class intervals against their respective frequencies and connecting these points with straight line segments. This distinguishes it from a frequency curve, which is typically a smooth line.
