,Question 10
Correlation Coefficient
Correct Answer
the statistical measure (symbolized as r) that indicates the strength and direction of
the relationship between two variables.
- between -1 and +1
- ex: +.7 = strong correlation
- #= strength, + or - = direction
- ex: which one has the strongest correlation
(+.6, +.73, -2.6, -.89) (-.89 is the strongest bc you ignore sign)
- + correlation= x and y increase
- - correlation= x goes decreases, y increases

appetite, and many other processes and behaviors.
Question 13

cord.

thyroxin.
Question 16
independent variable
Correct Answer
- cause
- manipulated by experimenter
Question 17
All-or-None
Correct Answer
a neuron either fires or doesn't fire; action potential are always the same strength.
