Which of the following is a drawback of using pie charts?

• They cannot represent proportions accurately.

• They are not suitable for categorical data.

• They may not accurately convey small differences in proportions.

• They are only effective for numerical data.

What does it mean if a wedge in a pie chart is larger than others?

• It represents the median of the dataset.

• It represents the mean of the dataset.

• It has a higher frequency within its category.

• It has a lower frequency within its category.

When should you avoid using a pie chart?
