Quizplus · Accepted Answer

The interquartile range (IQR) is defined as the difference between the 75th percentile (upper quartile) and the 25th percentile (lower quartile). It is a measure of the spread of the middle 50% of a distribution and is a more robust measure of variability than the standard deviation or variance, which can be affected by outliers. The coefficient of variation is the ratio of the standard deviation to the mean and is typically used in situations where the mean is not a meaningful measure of central tendency, such as when comparing the variability of two different variables with different units of measurement.
