non-experimental research a research method that does not involve manipulating an IV, but instead examines
relationships or behaviors in a natural setting
meta-analysis a statistical analysis that combines results from multiple studies on a topic
third variable problem another factor may be influencing both variables (ice cream sales and drowning
deaths are positively correlated, but hot weather explains the relationship
statistical signifigance (p-value) if p<0.05, the results are unlikely due to chance and are considered statistically
signifigant
effect size a larger effect size means the independent variable had a stronger influence on
the dependent variable
mean average
median middle number
mode most frequent number
normal distribution numbers: 1SD, 2SDs, 3SDs a normal distribution means most scores fall near the mean (bell curve)
-68% fall within 1 SD of the mean
-95% fall within 2SDs of the mean
-99.7% fall within 3SDs of the mean

positively skewed data the distribution's tail extends to the right, in a positive direction
negatively skewed data distribution's tail extends to the left, in a negative direction
biomdal distribution a graph with two peaks, suggesting two positive groups in the data
deception and confederates (a person who secretly sometimes necessary for study validity but must be justified and followed by
works with the experimenter, pretending to be a genuine debriefing
participant)
central nervous system brain and spinal cord
peripheral nervous system the network of nerves outside the brain and spinal cord that relay the messages
between the central nervous system and the rest of the body
autonomic nervous system the part of the peripheral nervous system that controls the glands and the
muscles of the internal organs (such as the heart). Its sympathetic division arouses;
its parasympathetic division calms.
somatic nervous system the division of the peripheral nervous system that controls the voluntary
movements of the skeletal muscles
neuron a nerve cell; the basic building block of the nervous system
glial cells cells in the nervous system that support, nourish, and protect neurons
reflex arc sensory receptor, sensory neuron, motor neuron, and effector that are involved in
automatic and involuntary responses to a stimulus
sensory neurons neurons that carry incoming information from the sensory receptors to the brain
and spinal cord
motor neurons neurons that carry outgoing information from the brain and spinal cord to the
muscles and glands
interneurons neurons within the brain and spinal cord that communicate internally and
intervene between the sensory inputs and motor outputs
