3. Positional measures are
also called fractiles or
quantiles.
Fractiles or quantiles
are positional measures
like the median, hence,
the method of
computation is similar
to the median
4. Quartiles are values that
divide the set of distribution
into four equal parts. These
values denoted by Q1, Q2, and
Q3 are such that 25% of the
data falls below Q1, 50% falls
below Q2, and 75% falls below
Q3 (Walpole, 1982:63).
