A frequency polygon is a type of line graph where the frequencies of classes are plotted against their midpoints. This graphical representation closely resembles a histogram and is typically used for comparing data sets or showing cumulative frequency distributions.
Frequency polygons are a type of line graph that helps in providing accurate data through a curved shaped line. Learn more about this interesting concept of frequency polygons, steps to plot, and solve a few examples.
A frequency polygon is almost identical to a histogram, which is used to compare sets of data or to display a cumulative frequency distribution. It uses a line graph to represent quantitative data. Statistics deals with the collection of data and information for a particular purpose.
Frequency polygons are analogous to line graphs, and just as line graphs make continuous data visually easy to interpret, so too do frequency polygons. To construct a frequency polygon, first examine the data and decide on the number of intervals, or class intervals, to use on the x -axis and y -axis.
What is a frequency polygon? A frequency polygon is a graph that shows the frequencies of grouped data. It is a type of frequency diagram that plots the midpoints of the class intervals against the frequencies and then joins up the points with straight lines.
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 a frequency polygon? A frequency polygon shows the overall distribution of a data set. It looks a little bit like a line graph–but the points on the graph can be plotted using data from a histogram or a frequency table. Frequency polygons are especially useful for comparing two data sets.
A frequency polygon is similar to a frequency diagram but uses connected lines to represent the frequencies rather than bars. A frequency diagram is a type of graph used to represent a...
A frequency polygon is used to display grouped data. To draw a frequency polygon we plot the midpoint of the group against the frequency and then join the points with straight lines
Frequency polygons give an idea about the shape of the data and the trends that a particular data set follows. Let us learn the step by step process of drawing a frequency polygon, with or without a histogram. The key objective of statistics is to collect and organize data.
