Question

what is the difference between a frequency polygon and an ogive? choose the correct answer below. a. it is easier to find patterns in the data from a frequency polygon than an ogive. b. a frequency polygon is a line graph while an ogive is a histogram. c. a frequency polygon displays class frequencies while an ogive displays cumulative frequencies. d. there is no difference between a frequency polygon and an ogive.

Explanation:

A frequency polygon is constructed by plotting class - midpoints on the x - axis and class frequencies on the y - axis and then connecting the points with line segments. An ogive is a graph of a cumulative frequency distribution, where the cumulative frequencies are plotted against the upper - class limits (for less - than ogive) or lower - class limits (for greater - than ogive). So the main difference is that a frequency polygon displays class frequencies and an ogive displays cumulative frequencies.

Answer:

C. A frequency polygon displays class frequencies while an ogive displays cumulative frequencies.
