a We are told that 100 students were surveyed about the sports they play. The results are shown in a circle graph.
We are asked to explain why the graph is misleading. Since a circle graph shows data as parts of a whole, the total of the numbers in the circle graph must be equal to 100. Let's add them to see if this requirement is fulfilled.
33+37+12+20+18=120Students
We can see that total of the numbers in the circle graph does not match the total number of students surveyed. Therefore, this is why the graph is misleading.
b Note that each sport is a different category. Therefore, a bar graph would be appropriate to display this qualitative data. Please note that this is only one of the many possible ways to display the data.
