Detailed Solution
Download Solution PDFThe correct answer is in a polygon, an additional line is not drawn at each to bring the graph back to a zero frequency.
Key Points
- A frequency polygon is a line graph that plots class frequency against the class midpoint. You can get it by connecting the midpoints of the rectangles' tops in the histogram.
- One must include the first and last class with zero frequencies in order to confirm that our graph is genuinely a polygon (i.e., the graph is closed-shape). Draw attention to the frequency column and the column with the midpoints for each class.
Additional Information
- A histogram is a bar graph with rectangle-shaped bars displaying the data, but a frequency polygon is a line graph with a curved line showing the data.
- A polygon has flat surfaces throughout. A polygon must have a minimum of three sides. Each side of a line segment must intersect another line segment only at its terminal. By counting the sides of a polygon, we may quickly ascertain its geometry.
Hence, for frequency distribution presentation, the wrong option is in a polygon, an additional line is not drawn at each to bring the graph back to a zero frequency.
