Bill believes he has a training program that can people improve their memories. he administers his training to one group of people (group a), while another group (group b) receives no training. he then compares the two groups' performance on a memory test. in this example, group a is the group. a) experimental b) control c) confound d) hypothesis

The correct answer is A. Experimental

Explanation:

In an experiment where two groups are being used to test a hypothesis or possible explanation to a phenomenon, the experimental group is the one in which the researcher intervenes or the one that receives special treatment. Moreover, the experimental group is the opposite of the control group that is the group with no treatment used as a standard in the experiment. This means, in BIll's experiment it is group A the experiment group because this is the group that receives training and therefore it is the group Bill is intervening.
