Quizplus · Accepted Answer

For the variable category of disability, mode would be the most appropriate measure of central tendency since it identifies the most common category within the dataset. Median and mean may not be as informative when dealing with categorical data. Range is not a measure of central tendency but rather a measure of dispersion.
