Question

multiple choice question
in a frequency polygon the points are plotted at the intersection of the class frequencies and the:
class midpoints
lower limits of the classes
upper limits of the classes

Explanation:

A frequency polygon is a graphical representation of frequency distributions. To create it, each data point is placed at the value that represents the center of its class interval, paired with the class frequency. This central value is the class midpoint, as it accurately represents the entire class for plotting purposes.

Answer:

class midpoints
