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.

well, paralell is parallel. i am providing links to .

hope this !

a series circuit is one with all the loads in a row. there is only one path for the electricity to flow. if this circuit was a string of light bulbs, and one blew out, the remaining bulbs would turn off.

unlike in series circuits, a charge in a parallel circuit encounters a single voltage drop during its path through the external circuit. the current through a given branch can be predicted using the ohm's law equation and the voltage drop across the resistor and the resistance of the resistor.

a parallel circuit has certain characteristics and basic rules: a parallel circuit has two or more paths for current to flow through. voltage is the same across each component of the parallel circuit.
