Positional averages like the median are calculated based on the ordered arrangement of data, while other measures like the mean and mode may not depend on the order of data.
A positional average is a measure of central tendency that depends on the position of values in a dataset. The median is a positional average because it depends on the position of the values when they are arranged in order. The mean, mode, and range do not rely on the position of the data points in the dataset.
