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.
Graphical display of the frequency table can also be achieved through a frequency polygon. To create a. the intervals are labeled on the X-axis and the Y axis represents the height of a point in the middle of the interval. The points are then joined are connected to the X-axis and thus a polygon is formed.So, frequency polygon is a graph that is obtained by connecting the middle points of the intervals. We can create a frequency polygon from a histogram also.If the middle top points of the bars of the histogram are joined, a frequency polygon is formed. Frequency polygon and histogram fulfills the same purpose.o create a. the intervals are labeled on the X-axis and the Y axis represents the height of a point in the middle of the interval. The points are then joined are connected to the X-axis and thus a polygon is formed. So, frequency polygon is a graph that is obtained by connecting the middle points of the intervals.
