BASIC STATISTICAL TOOLS
INTRODUCTION
• The statistical operations are necessary to control and
verify the analytical procedures as well as the resulting
data.
• Making mistakes in analytical work is unavoidable. This
is the reason why a complex system of precautions to
prevent errors and traps to detect them has to be set up.
• An important aspect of the quality control is the
detection of both random and systematic errors. This
can be done by critically looking at the performance of
the analysis as a whole and also of the instruments and
operators involved in the job.
