   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.

   {Board of control}. See under {Board}.
      [1913 Webster]
    

control
ctrl

   <character> (Or "ctrl", "^") One (or a pair) of {modifier
   keys} found on all modern {keyboards}.  If the control key is
   held down while pressing and releasing certain other keys then
   a "{control character}" is generated, e.g. holding control and
   hitting "A" generates control-A ({ASCII} code 1).  The ASCII
   code for the control character is generally 64 less than that
   for the unmodified character.

   The control key does not generate any character on its own but
   most modern keyboards and {operating systems} allow a program
   to tell whether each of the individual keys on the keyboard
   (including modifier keys) is pressed at any time.

   Control characters mostly have some kind of "non-printing"
   effect on the output such as ringing the bell (Control-G) or
   advancing to the next line (Control-J).  Most have alternative
   names suggesting these functions (Bell, Line Feed, etc.).

   See {ASCII character table}.
