independent variable - answer in an experiment: the factor that is
changed by the experimenter and is not affected by any other
factor.
dependent variable - answer in an experiment: the factor that
changes value as another factor is changed by the experimenter.
experimental group - answer in an experiment: a group of samples,
etc. that receives the experimental treatment or factor
positive control - answer in an experiment: a control group that is
treated in the same manner as the experimental group and and is
designed to give a positive result
negative control - answer in an experiment: a control group that is
treated in the same manner as the experimental group and and is
designed to give a negative result
control group - answer in an experiment: a group of samples, etc.
that is treated in the same way as the experimental group, but does
not receive the experimental treatment or factor. this group shows
the background level or response and is used for comparison to the
experimental group.
