A frequency polygon is a type of line graph that shows the frequency of a mutually exclusive event occurring. Sam and Jessica can use a frequency polygon to compare their data and see, once and for all, who has the best archery students. It allows you to see the proportion or percentage that one value is repeated among all the elements in the sample. Relative frequencies of class intervals also can be shown in a frequency polygon.In this chart, the frequency of each class is indicated by points or dots drawn at the midpoints of each class interval. We have a new and improved read on this topic. Indeed, these relative frequency graphs will look like the corresponding graphs of the absolute frequencies except that the labels on the vertical axis are now the old labels (that gave the frequencies) divided by the total number of data points. The tabulation of each run for each ball in cricket gives the statistics of the game. Frequency tables display the values of a variable, weighted with the number of occurrences of each single value. Just enter your scores into the textboxes below, either one value per line or as a comma delimited list, with one distribution per box, and then hit the "Generate" button.
