The sections of a pie chart do not add up to the whole circle. What does this show?

Answer and explanation

Correct answer: There is an error in the data or proportion calculations

The governing concept is that a pie chart represents one complete total. Therefore, all sector angles must add to 360° and all percentages must add to 100%. If the sectors do not complete the circle, the data may have been entered incorrectly or the proportions and angles may have been calculated wrongly. Colour choices and title size affect appearance, not mathematical accuracy. Thus, option C is correct.
