Straighterline PSY 101| ACTUAL EXAM QUESTIONS
WITH ANSWERS VERIFIED 100% CORRECT
Four goals of psychology - ✔✔Describe, Predict, Understand, & Influence
Research with nonhuman animals is considered to be ethical only when the following
three conditions are met - ✔✔Necessity, Health, Humane Treatment
Scientific method - ✔✔A systematic approach to acquiring knowledge that is based
on empirical observation and rules of evidence.
Coefficient of correlation - ✔✔A number (ranging from -1.0 to +1.0) that is a
statistical expression of the strength and direction of the relationship between two
variables.
Variable - ✔✔Any factor or characteristic—such as age, height, gender, grade-point
average, etc.—that can vary.
Independent variable - ✔✔The factor in a formal experiment that is manipulated by
the researcher.
Dependent variable - ✔✔The factor in a formal experiment that is expected to vary in
response to changes in the independent variable.
Experimental group - ✔✔Any group participating in an experiment that receives
some treatment or level of the independent variable.
, Sample - ✔✔A group of individuals taken from the larger population, ideally designed
to be representative of the whole.
Control group - ✔✔The group in an experiment that is used for comparison purposes
and does not receive the treatment or condition being tested.
Placebo effect - ✔✔Changes in behavior that occur simply due to people's
expectations and not due to actual treatment, such as when they feel better after being
given a sugar pill that has no active ingredient
Replication - ✔✔Experiments that attempt to duplicate findings of a previous study in
order to confirm their validity and increase people's confidence in the results.
Random assignment - ✔✔A method of assigning study participants to different
groups by a chance-based method (such as drawing names out of a hat, or random
assignment by computer).
Double-blind procedure - ✔✔An experimental method where neither experimenter
nor participant know which was assigned to the experimental and control groups. This
prevents experimental bias.
Hypothesis - ✔✔A precise prediction about some causal factor or other phenomenon
that can be tested in an experiment.
Theory - ✔✔A tentative, broad explanation or prediction that is the starting point in
formulating a hypothesis.
Naturalistic observation - ✔✔A research method in which behavior is simply
recorded as it happens in a natural setting.
