Definition: Interquartile range is the measure of dispersion which is the difference in the values of two quartiles. The Lower Quartile is denoted as Q 1 and the Upper Quartile is denoted as Q 3. The interquartile range is Q 3 - Q 1. Semi Interquartile range is the midpoint of the interquartile range. In other words, it is one-half of the difference between the third quartile and the first quartile. Therefore, Semi-Interquartile range = $\frac{Q_{3}-Q_{1}}{2}$. Where Q 1 and Q 3 are the upper and lower quartiles respectively.
Statisticians use summary measures to describe the amount of variability or spread in a set of data. The most common measures of variability are the range, the interquartile range (IQR), variance, and standard deviation. View Video Lesson The Range. The range is the difference between the largest and smallest values in a set of values. For example, consider the following numbers: 1, 3, 4, 5, 5, 6, 7, 11. For this set of numbers, the range would be 11 - 1 or 10. The Interquartile Range (IQR) The interquartile range (IQR) is a measure of variability, based on dividing a data set into quartiles. Quartiles divide a rank-ordered data set into four equal parts. The values that divide each part are called the first, second, and third quartiles; and they are denoted by Q1, Q2, and Q3, respectively. 1  Q1 is the middle value in the first half of the rank-ordered data set. 2  Q2 is the median value in the set. 3  Q3 is the middle value in the second half of the rank-ordered data set.
