Read each question carefully and follow the instructions to create or interpret frequency polygons.
A frequency polygon is a graph that uses line segments to connect the midpoints of the tops of the bars in a histogram. It helps us visualize the shape of the data distribution.
1. A frequency polygon is made by connecting the of the tops of histogram bars.
2. It helps to visualize the of the data distribution.
3. The X-axis of a frequency polygon usually represents the or categories.
4. The Y-axis of a frequency polygon usually represents the .
1. Look at the bar graph below showing the number of books read by students in a month. Imagine you are drawing a frequency polygon for this data. Describe how you would connect the points.
1. Which of the following is NOT a characteristic of a frequency polygon?
It uses line segments.
It connects the midpoints of histogram bars.
It uses bars to show frequency.
It shows the shape of data distribution.
1. A frequency polygon is always closed at both ends, touching the x-axis.
True
False
2. Frequency polygons are only used for categorical data.
True
False
The following table shows the number of minutes students spent on homework last night: Minutes | Frequency ---|--- 0-20 | 5 21-40 | 12 41-60 | 8 61-80 | 3 1. Plot the midpoints of each interval on the graph paper below and connect them to create a frequency polygon. Remember to close the polygon by connecting to the x-axis at the midpoints of the imaginary intervals before and after your data.
2. What does the shape of your frequency polygon tell you about the amount of time students spent on homework?
