The median of a finite list of numbers is the "middle" number, when those numbers are listed in order from smallest to greatest. If the data set has an odd number of observations, the middle one is selected. For example, the following list of seven numbers, 1, 3, 3, 6, 7, 8, 9 WebThe formula for finding the interquartile range takes the third quartile value and subtracts the first quartile value. IQR = Q3 – Q1. Equivalently, the interquartile range is the region between the 75th and 25th percentile (75 – 25 = 50% of the data). Using the IQR formula, we need to find the values for Q3 and Q1.

WebThe mean is also referred to as the balancing point of a distribution. If we measure the distance between each data point and the mean, the distances are balanced on each side of the mean. The median is the physical center of the data when we make an ordered list. It has the same number of values above it as below it.
