Sensational Show The Following Data By A Frequency Polygon

Seeing the data in this format helps us visualize and understand it better.

Show the following data by a frequency polygon. Show the following data by a frequency polygon. For most of the work you do in this book you will use a histogram to display the data. The heights are represented on the horizontal axes on a suitable scale as shown.

A histogram is a series of rectangular bars with no space between them and is used to represent frequency distributions. The following distribution table represents the number of miles run by 20 randomly selected runners during a recent road race. The endpoints touch the X-axis.

After choosing the appropriate ranges begin plotting the data points. A rule of thumb is to use a histogram when the data. Bin Frequency 55105 1 105155 3 155205 2 205255 4 255305 5 305355 3 355405 2.

The following steps will be useful to draw frequency polygon without histogram. A frequency polygon was constructed from the frequency table below. This frequency diagram shows the heights of 200 people.

This way the area of the polygon remains the same as that of the histogram. Plot the points corresponding to the frequency at each mid point. A frequency polygon is a type of line graph that shows the frequency of a mutually exclusive event occurring.

IiShow that the area under frequency polygon is equal to the area under hist. One advantage of a histogram is that it can readily display large data sets. To construct a frequency polygon first examine the data and decide on the number of intervals or class intervals to use on the latexxlatex-axis and latexylatex-axis.
