A frequency polygon is a line graph of class frequency plotted against class midpoint. It can be obtained by joining the midpoints of the tops of the rectangles in the histogram (cf. Fig. 3.3.).
What is frequency polygon with example?
A frequency polygon is a visual representation of a distribution. The visualization tool is used to understand the shape of a distribution. Essentially, the frequency polygon indicates the number of occurrences for each distinct class in the dataset.
What is frequency polygon What are its uses?
Frequency polygons are a graphical device for understanding the shapes of distributions. They serve the same purpose as histograms, but are especially helpful for comparing sets of data. Frequency polygons are also a good choice for displaying cumulative frequency distributions.
What is frequency polygon in geography?
Frequency polygon is a graph showing the frequency distribution. It is drawn by joining the middle points of the upper side of the adjacent rectangles or bars of the histogram with straight lines.
What is cumulative frequency diagram?
A cumulative frequency diagram is drawn by plotting the cumulative frequency against the upper class boundary of the respective group. The upper class boundaries for this table are 35, 40, 45, 50 and 55. Cumulative frequency is plotted on the vertical axis and length is plotted on the horizontal axis.
What is frequency polygon in statistics Slideshare?
FREQUENCY POLYGON frequency polygon: graph that uses lines that connect points plotted for the frequencies at the midpoints of the classes; frequencies are represented by the heights of the points To construct a frequency polygon: Find the midpoints of each class Draw the x and y axes.
What is the advantage of a frequency polygon?
The advantages of frequency polygon are: The frequency polygon not only sorts and represents the data but also makes it easy to make the comparison of the data given. Frequency polygons are easy to understand and remember as to provide a clear view of the distribution data.
What are the features of frequency polygon?
A frequency polygon is a graph constructed by using lines to join the midpoints of each interval, or bin. The heights of the points represent the frequencies. A frequency polygon can be created from the histogram or by calculating the midpoints of the bins from the frequency distribution table.
What is difference between histogram and frequency polygon?
1. Frequency polygon is an improvement over histogram because it provides a continuous curve indicating the causes of rise and fall in the data. On the other hand, frequency polygon is an approximate curve, but still it is more usefui as compared to histogram. 2.
What is frequency polygon for Class 9?
A frequency polygon is a graphical form of representation of data. It is used to depict the shape of the data and to depict trends. It is usually drawn with the help of a histogram but can be drawn without it as well.
