PSYCHOLOGY 110 EVALUATION EXAM 2026/2027
QUESTIONS AND SOLUTIONS RATED A+
✔✔What is the role of treatment and control groups in research? - ✔✔They help to
determine whether the experimental manipulation produced the observed results.
✔✔What is the purpose of using both experimental and control groups in research? -
✔✔To rule out the possibility that something other than the experimental manipulation
produced the results.
✔✔Define independent variable. - ✔✔The variable that is manipulated by an
experimenter.
✔✔Define dependent variable. - ✔✔The variable that is measured in an experiment and
is expected to change as a result of the manipulation of the independent variable.
✔✔What is random assignment of participants? - ✔✔A procedure in which participants
are assigned to different experimental groups based on chance alone.
✔✔What does a significant outcome indicate in research? - ✔✔That the findings of a
research study are statistically meaningful.
✔✔What is replicated research? - ✔✔The repetition of research using different
procedures, settings, and groups to increase confidence in prior findings.
✔✔What is a meta-analysis? - ✔✔A procedure that allows psychologists to combine
results from many separate studies into one overall conclusion.
✔✔What are the ethical guidelines for protecting research participants? - ✔✔Protection
from physical and mental harm, privacy, voluntary participation, and informed consent.
✔✔What is informed consent? - ✔✔A document signed by participants affirming they
have been informed about the study and what their participation involves.
✔✔What is debriefing in research? - ✔✔An explanation provided to participants after a
study about the study's purpose and procedures.
✔✔What are the conditions under which informed consent can be eliminated? -
✔✔When risks are minimal, such as in purely observational studies in public places.
✔✔What are the ethical considerations for using animals in research? - ✔✔Minimizing
discomfort and promoting well-being, while allowing procedures that might not be ethical
with humans.
, ✔✔What is experimental bias? - ✔✔Factors that distort how the independent variable
affects the dependent variable in an experiment.
✔✔What is a placebo? - ✔✔A false treatment without any significant chemical
properties or active ingredient.
✔✔What is a double-blind procedure? - ✔✔A method where both the experimenter and
the participant are unaware of the treatment being administered.
✔✔What does the diffusion of responsibility theory explain? - ✔✔That as the size of the
group witnessing an emergency increases, helping behavior decreases.
✔✔What was the focus of the Latané and Darley experiment? - ✔✔To test the
hypothesis regarding the diffusion of responsibility in emergency situations.
✔✔What are the basic steps in conducting a true experiment? - ✔✔Identify participants,
randomly assign them to conditions, manipulate the independent variable, measure the
dependent variable, and compare results.
✔✔What is the role of operational definitions in research? - ✔✔To specify how variables
will be measured and manipulated in a study.
✔✔What is the significance of statistical tests in research? - ✔✔They help confirm
whether differences between groups are large enough to be considered significant.
✔✔What is the importance of communicating findings in research? - ✔✔To share
results and contribute to the body of knowledge in psychology.
✔✔What is the relationship between participant expectations and experimental results?
- ✔✔Participant expectations can affect results, highlighting the need to control for bias.
✔✔What is the impact of group size on helping behavior according to Latané and
Darley's findings? - ✔✔The smaller the number of bystanders, the greater the degree of
helping behavior.
✔✔What is the significance of replication studies? - ✔✔They are critical for confirming
the reliability and validity of original research findings.
✔✔What are the potential consequences of not following ethical guidelines in research?
- ✔✔Participants may suffer physical or mental harm, and the integrity of the research
may be compromised.
✔✔What is psychology? - ✔✔The scientific study of behavior and mental processes.
