FROM CHAPEL HILL TO A+: ULTIMATE
PSYC 101 EXAM 1 REVIEW – DR. LOEB’S
FRAMEWORK (2026/2027)
Empiricism - THE CORRECT ANSWER-learning from first hand
experience, using senses
Descriptive statistics - THE CORRECT ANSWER--central tendency
(mean mode)
-dispersion of scores (standard deviation, variance)
-correlation
Correlation - THE CORRECT ANSWER--represented by "r"
-strength: 0 to 1
-r= .2 negligible
-r= .5 moderate
-r= .8 very strong
-r= 1 perfect relationship
Inferential statistics - THE CORRECT ANSWER--T- tests, Chi test, F-
test, Multiple regression
-math calculation tells whether or not it is likely okay to
generalize from sample results to population
, Levels - THE CORRECT ANSWER-number of ways variable is
manipulated
Confounding variable - THE CORRECT ANSWER-inconclusive study-
not only influences results, but does so in a way that it makes
results unclear
Extraneous variable - THE CORRECT ANSWER-variables which may
influence results, though you are not interested in its effects
Quasi-experiment - THE CORRECT ANSWER-looks like experiment but
the independent variable has not been manipulated by the
experimenter
Glia - THE CORRECT ANSWER-glue of the brain
Oligodendrocytes - THE CORRECT ANSWER-CNS, one cells can create
several segments of myelin sheath and cover more than one
axon
Schwann cell - THE CORRECT ANSWER-PNS, one cell creates only one
segment of myelin sheath for only one axon
Astrocytes - THE CORRECT ANSWER-Synchronizes communication
between neurons, nurtures cells, and removes waste products
Microglia - THE CORRECT ANSWER-Functions as part of immune
system, removes waste products & invaders such as bacteria &
viruses
