FOR SUCCESS
critical thinking - CORRECT ANSWERS process of evaluating claims or hypotheses and
making judgments about them on the basis of well-supported evidence
hypothesis - CORRECT ANSWERS a prediction stated as a testable proposition, usually
in the form of an if-then statement
variables - CORRECT ANSWERS specific factors or characteristics that are manipulated
and measured in research
data - CORRECT ANSWERS numbers that represent research findings and provide the
basis for research conclusions
operational definition - CORRECT ANSWERS a statement of the specific methods used
to measure a variable; a detailed explanation of the variable
theory - CORRECT ANSWERS cluster of explanations of a phenomenon that help
predict, explain, and control that behavior
naturalistic observation - CORRECT ANSWERS method gathering descriptive
information involving watching behaviors, without interfering, as they naturally occur
case study - CORRECT ANSWERS used to collect descriptive data through the intensive
examination of a phenomenon in a particular individual, group, or setting (particularly useful for
rare or complex phenomena)
survey - CORRECT ANSWERS questionnaire or interview administered to a large group;
designed to obtain descriptions of peoples' behaviors/beliefs

correlational studies - CORRECT ANSWERS research method that examines
relationships between variables in order to analyze trends in data, test predictions, etc. (they
do NOT discern cause and effect relationships)
experiment - CORRECT ANSWERS the only research method to show causation, this
involves obtaining a random sample of subjects and using control and experimental groups;
allows a researcher to control the data-collection process
independent variable - CORRECT ANSWERS controlled by the researcher, experienced
by the control group, this is what the researcher thinks will HAVE an effect on some other
behavior
dependent variable - CORRECT ANSWERS behavior affected by another variable, it is
observed and measured (usually before and after and experiment takes place)
experimental group - CORRECT ANSWERS receives the critical part of the experiment
(the independent variable)
control group - CORRECT ANSWERS provides a baseline for comparison, does not
receive critical treatment (independent variable)
experimenter bias - CORRECT ANSWERS occurs when experimenters ask leading
questions or otherwise search for evidence that supports their hypothesis and don't look for
evidence that refutes it
random variable - CORRECT ANSWERS a confounding variable in which uncontrolled
factors affected the dependent variable along with or instead of the independent variable

FOR SUCCESS
random assignment - CORRECT ANSWERS random distribution of participants to
experimental or control groups - used to distribute the impact of uncontrolled variables
randomly, and most likely evenly, across the groups, minimizing the chance they will distort the
results
placebo effect - CORRECT ANSWERS improvement caused by a participant's knowledge
and expectations: can be from a treatment that contains nothing known to be helpful, but that
nevertheless produces benefits because a person believes it will be beneficial.
confounding variable - CORRECT ANSWERS any factor that affects the dependent
variable, along with or instead of the independent variable
double-blind design - CORRECT ANSWERS design for research in which neither the
experimenter nor the subjects know who is in the experimental or control group
sampling - CORRECT ANSWERS the process of selecing participants for research who
are members of the population the researcher wishes to study
generalize - CORRECT ANSWERS to apply the results of one's study to people beyond
just the researcher's sample
representative sample - CORRECT ANSWERS a group of subjects whose characteristics
fairly reflect the characteristics of the population they belong to
random sample - CORRECT ANSWERS a group of subjects selected froma population
whose members all had an equal chance of being selected

biased sample - CORRECT ANSWERS a group of research subjects selected froma
population whose members did not all have an equal chance of being chosen
sampling error - CORRECT ANSWERS part of a sampling process that results in a biased
sample
convenience sample - CORRECT ANSWERS when researchers draw participants from
the populations that are readily available to them
twin studies - CORRECT ANSWERS study the heredity-environment question by
comparing the similarity seen in identical twins with those of nonidentical pairs
descriptive statistics - CORRECT ANSWERS numbers that describe and summarize a set
of research data
inferential statistics - CORRECT ANSWERS set of mathematical procedures that help
researchers learn if their research data reflects a true relationship or could be due to random
chance
mode - CORRECT ANSWERS measure of central tendency that is the value that occur
most frequently in a data set
median - CORRECT ANSWERS measure of central tendency that is the halfway point in
a set of data
