|
STATISTICAL SIGNIFICANCE:
|
Experimental result that would occur by chance in less than one experiment in 20; the accepted level in modern science
|
|
|
POSITIVE FEEDBACK
|
There is a end point in sight
example: you get cut, your body produces a clotting agent. The more you bleed the more clotting agent it produces. result is scab |
|
|
NEGATIVE FEEDBACK
|
The effector eliminates the stimuli
example: you get hot, your body makes you sweat. results in your tempature lowering. |
