If a participant begins a study but fails to complete it, then that participant is a(n) .

I believe the answer is: Dropout

In research environment, a dropout describes the subjects who fail to fulfil the programs that created by the researchers from the beginning to the end. This would made every data that taken from the subject become inadmissible to make the research conclusion.

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.

they encountered severe weather for which they were poorly prepared.
