Abstract
There are many situations in which the simultaneous monitoring or control of two or
more related quality characteristics is necessary. Multivariate analysis utilize the
additional information due to the relationships among the variables and these concepts
may be used to develop more efficient control charts than the simultaneous operation of
several university control charts. The most popular multivariate statistical process
control SPC are the Hotelling's T2

chart. In this paper the S/N ratio is analyzed and
response effect level are calculated with optimizing the response effect level And to
explain which of variable is important and necessary to test the chemical analysis in
Thyroid gland.

Key Words: HotellingT2 .chart Signal-to-noise ratio S/N.
