When the data set contains an odd number of values, the
data set's median value is not used when calculating Q1
and Q3 in the table above. For example, for the following
data set:
{3,5,7,8,15,16,17}
only the first three items, 3, 5, and 7 are used to calculate
Q1, and only the last three terms, 15, 16, and 17 are
used to calculate Q3.
