experimental group

or

experimental condition

the group which receives the INDEPENDENT VARIABLE in an experiment. Typically, in the EXPERIMENTAL METHOD, the EXPERIMENTAL HYPOTHESIS is tested by treating the experimental group with the independent variable to be investigated, and comparing any resultant effect (measured by the DEPENDENT VARIABLE) with any change observed in the CONTROL GROUP. If a statistically significant difference is found between the dependent measures in experimental and control groups, then the experimental hypothesis is upheld. If there is no statistically significant difference, then the NULL HYPOTHESIS is upheld.
