Is it possible to determine the mode?
The mode can be determined. The mode is the category that occupies the portion of the circle graph that is on the opposite side of the circle from the location where the first category begins.
The mode cannot be determined because categorical data do not have a mode. Only numerical data have a mode.
The mode cannot be determined because a circle graph does not display frequencies.
The mode can be determined. The mode is the category represented by the largest sector of the circle graph.
