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.
Frequency Tables. Often data is presented in the form of a frequency table. For example, the data in range A4:A11 of Figure 1 can be expressed by the frequency table in range C4:D7. The table in Figure 1 shows that the data element 2 occurs 4 times, the element 4 occurs 2 times and the element 3 and 5 occur 1 time.
