Exhibit 2 presents the cost of treating each of the 426 million cases of illness. Average treatment costs varied by country. Ukraine maintained the highest cost of treatment for all diseases at $62 for malaria, $1,113 for meningitis, $21 for pertussis, $264 for pneumonia, and $42 for rotavirus.xhibit 2 presents the cost of treating each of the 426 million cases of illness.

Frequency Polygons. A frequency polygon is another way to show the information in a frequency table. It looks a little bit like a line graph. To make a frequency polygon, you just need to plot a few points and then join the points by straight lines.he reason itâs called a polygon is because the line sort of forms a plane shape with the horizontal axis as one side of the shape: Now a frequency polygon and a histogram both show the same information, but in a different way.
A histogram is constructed from a frequency table, thus its name frequency histogram. The intervals from the table are placed on the x-axis and the values needed for the frequencies are represented on the y-axis.umulative Frequency Histogram: The cumulative frequency is the running total of the frequencies. On a graph, it can be represented by a cumulative frequency polygon. The graph will look like a bar graph that shows the data after it has been added from the smallest interval to the largest interval.
