the important features of a
group of data

10. Dispersion the spread of data; most
simply estimated by the
range, the ditterence be-
tween the largest and
smallest observations. The
most commonly used sta-
tistic for describing the
dispersion of groups of
single observations is the
standard deviation, which
is usually represented by
the symbol s.

11. Standard Deviation Index: SDI A calculation to show the
number of SDs a value is
from the target mean

12. Reference interval the usual values for a
healthy population; also
normal range

13. Reference method an analytical method used
for comparison. It is a
method with negligible
inaccuracy in comparison
with its imprecision.

14. linear regression statistical calculations of
the slope (b), the y inter-
cept (a), and the standard
