Control \Con*trol"\, n. [F. contr[^o]le a counter register,
contr. fr. contr-r[^o]le; contre (L. contra) + r[^o]le roll,

or machine in operation, as a flying machine in flight;
specifically (A["e]ronautics), the mechanism controlling

5. (Climatology) Any of the physical factors determining the
climate of any particular place, as latitude,distribution
of land and water, altitude, exposure, prevailing winds,
permanent high- or low-barometric-pressure areas, ocean

6. (Technology) in research, an object or subject used in an
experimental procedure, which is treated identically to
the primary subject of the experiment, except for the
omission of the specific treatment or conditions whose
effect is being investigated. If the control is a group of
living organisms, as is common in medical research, it is
called the

{control group}.

Note: For most experimental procedures, the results are not
considered valid and reliable unless a proper control
experiment is performed. There are various types of
control used in experimental science, and often several
groups of subjects serve as controls, being subjected
to different variations of the experimental procedure,
or controlling for several variables being tested. When
the effects caused by an experimental treatment are not
consistent and obvious, statistical analysis of the
results is typically used to determine if there are any
significant differences between the effects of
different experimental conditions.
[PJC]

7. (Technology) the part of an experimental procedure in
which the controls[6] are subjected to the experimental
conditions.
[PJC]

8. the group of technical specialists exercising control by
