PSY 395 Exam 2 Questions and Correct
Answers with Complete Solutions | New
Update 2026
Experimental Control - ANSWERS The practice of maintaining consistent
conditions in an experiment to isolate and measure the impact of IV on DV.
Manipulate Independent Variable - ANSWERS To change the IV's level
systematically so different groups of participants are exposed to different levels of
var. OR the same group of participants are exposed to different levels at different
times.
Single-factor Two-level Design - ANSWERS Examines the effect of a single IV
with only two levels (ie. High vs low temp) on a DV.
Single-factor Multi-level Design - ANSWERS Examines the effect of a single IV
but with more than two levels (ie study duration: 1 hr, 2 hr, 3 hr).
Factorial Design - ANSWERS Type of experiment where multiple factors are
varied simultaneously to study their individual effects and how they interact with
each other (studies two or more IV simultaneously).
Random Assignment - ANSWERS Assigning participants to conditions so that
every participant has an equal chance of being placed in any condition.
, Importance of Random Assignment - ANSWERS Provides additional control
and eliminates the effects of individual differences.
Treatment in Experimental Context - ANSWERS Intervention meant to change
people's behavior for the better.
Randomized Clinical Trial - ANSWERS Trials that test the efficiency of
psychotherapies and medical treatments; participants are assigned by chance into
different groups to compare the effects of treatments.
Wait-list Control - ANSWERS Participants are assigned to receive the new
treatment after the experimental treatment group has completed the trial; used
to study the effects of a treatment when placebo is not feasible.
Control Condition - ANSWERS A group that receives an existing, established
treatment that is considered the standard; used to compare new treatment's
effectiveness.
Placebo - ANSWERS Participants receive a 'dummy' treatment that looks
identical to experimental treatment; used to measure the placebo effect and
determining if a new study is truly effective.
Independent Measures/Between-Subjects Design - ANSWERS A research
design that uses a separate sample for each treatment condition.
Dependent Measures/Within-Subjects Design - ANSWERS A design that uses
the same sample for multiple treatment conditions (ie before and after diet
program).
