Consider a table that summarizes the occurrence of COVID-19 cases in different countries. Such qualitative data with the frequency counts can be represented using the Pie chart, a graph in the form of a circle, just like a pie. So, how is the data from a table converted into a pie chart? First, divide the number of COVID cases in country A by the sum of all the COVID cases. Multiply this value by 360 degrees—the degrees in a full circle—to get the sector angle of the corresponding country. Similarly, calculate the sector angles for the other countries. Using these sector angles, divide the circle into slices equivalent to the given number of categories. Notice that the percentage frequencies of COVID cases also correspond to the size of their slices. Here, country E, with the largest sector, indicates the highest percentage of COVID cases. In contrast, country F, with the smallest sector angle, shows the least percentage of cases.
