Question

Quizplus · Accepted Answer

For nominal level variables, which are categorical and do not have a natural order, discussing dispersion in terms of percentage distribution is appropriate. This method allows for the representation of how frequently each category occurs relative to the others. Standard deviation, minimum and maximum, and range are measures used for interval or ratio level data, which have a meaningful order and fixed intervals.
