PSYC 255 QUIZ 5 COMPREHENSIVE TEST
PAPER 2026 QUESTIONS WITH ANSWERS
GRADED A+
⫸ Correlation Coefficient Answer: Number from -1 to +1, indicating
the strength and direction of the relationship, usually represented as a
Pearson's r.
⫸ Correlation Answer: Measurement of a relationship between two or
more variable.
⫸ Control Group Answer: Serves as a basis for comparison with
experimental groups, attempts to control for chance factors that may
influence the DV, isolating the IV as the only significant difference
between the control and experimental groups.
⫸ Confounding Variable Answer: Unanticipated outside factor that may
affect independent and dependent variables, sometimes gives the false
impression that IV and DV are related to each other, when in actuality,
they are both related only to the __.
⫸ Confirmation Bias Answer: Tendency to ignore evidence that
disproves one's ideas or beliefs.
⫸ Case Study Answer: Research focusing on one or few people.
, ⫸ Cause-And-Effect Relationship Answer: Changes in one variable
cause the changes in the other variable; can be determined through an
experimental research design.
⫸ Blinding Answer: An experimental design strategy intended to reduce
reactivity and placebo effects.
⫸ Attrition Answer: Reduction in the number of research participants
over time, sometimes they drop out, sometimes they die (Can occur in
older adult longitudinal research).
⫸ Archival Research Answer: Method of research using past records or
data sets to answer various research questions, or to search for
interesting patterns of relationships in those data.
⫸ Generalize Answer: Inferring that the results for a sample apply to the
larger population.
⫸ Falsifiable Answer: Able to be disproven.
⫸ Fact Answer: Objective and verifiable observation, established using
evidence collected through empirical research.
⫸ Experimenter Bias Answer: Researchers expectations can and do
skew the results of their study.
