The interquartile range is calculated using the middle 50% of a dataset, which excludes the highest and lowest scores. This makes it a more robust measure of variability compared to the range, which is affected by extreme scores. The standard deviation also takes into account all scores, including outliers, so it is not the best choice in this scenario. The median is a measure of central tendency and not variability.
