Since the lower and upper quartiles are themselves medians of reduced data sets they can be computed by the general algorithm given above for computing medians. For example the list 22 22 24 26 26 has modes of 22 and 26. Example The median of 35 54 58 60 67 is 58 which is the middle value of the set.
Definition Order the values of a data set of size n from smallest to largest.
The median is often denoted by x pronounced x-tilde. The median occurs midway between the 50 th and 51 st values. One-quarter of the observations fall below the first quartile which is denoted as Q1. The sample variance will be denoted by s 2 and the population variance will be denoted by s 2.
