Question

Quizplus · Accepted Answer

Nominal level of measurement is the lowest level of measurement where the data are divided into distinct categories or groups. Therefore, it is meaningful to obtain a frequency distribution and a bar chart to represent these categories or groups. However, it is not meaningful to obtain a mean, median or mode as these are measures of central tendency that require numerical values. The interquartile range is also not meaningful as it requires ordered data.
