Quizplus · Accepted Answer

The ordinal level of measurement only allows for ranking data in order, so obtaining a frequency distribution or bar chart can help visualize the relative frequencies of each rank. However, measures of central tendency like mean, median, and mode are not useful since they require numerical values, which are not present in ordinal data. Likewise, standard deviation is not useful since it also requires numerical values and assumes equal intervals between them.
