Read each question carefully and follow the instructions to construct or interpret frequency polygons.
1. What is a frequency polygon used to represent in statistics?
2. A frequency polygon is constructed by plotting the of each class interval against its corresponding frequency.
3. The first and last points of a frequency polygon are usually connected to the on the x-axis.
4. Which of the following is NOT a characteristic of a frequency polygon?
It uses line segments.
It is suitable for continuous data.
It uses bars to show frequency.
It shows the shape of the data distribution.
5. Construct a frequency polygon for the following data representing the scores of students in a math test:
Scores: 10-20 (Frequency: 5), 20-30 (Frequency: 8), 30-40 (Frequency: 12), 40-50 (Frequency: 7), 50-60 (Frequency: 3)
6. Look at the frequency polygon you constructed in Question 5. What does the shape of the polygon tell you about the distribution of scores?
