Psychology 101 Final Exam questions and answers
2026\2027 A+ Grade
Variables
- correct answer the events, characteristics, behaviors, or conditions that researchers measure and
study.
subject or participant
- correct answer an individual person or animal a researcher studies.
Sample
- correct answer a collection of subjects researchers study. Researchers use samples because they
cannot study the entire population.
Population
- correct answer the collection of people or animals from which researchers draw a sample. Researchers
study the sample and generalize their results to the population.
The Purpose of Research
- correct answer -To find ways to measure and describe behavior
-To understand why, when, and how events occur
-To apply this knowledge to solving real-world problems
The scientific method
- correct answer a standardized way of making observations, gathering data, forming theories, testing
predictions, and interpreting results.
A theory
- correct answer an explanation that organizes separate pieces of information in a coherent way.
, replicable
- correct answer when others can repeat an experiment and get the same results.
hypothesis
- correct answer a testable prediction of what will happen given a certain set of conditions.
naturalistic observation
- correct answer researchers collect information about subjects by observing them unobtrusively,
without interfering with them in any way.
case study
- correct answer The researcher collects data about the subject through interviews, direct observation,
psychological testing, or examination of documents and records about the subject.
survey
- correct answer a way of getting information about a specific type of behavior, experience, or event.
When using this method, researchers give people questionnaires or interview them to obtain
information.
experiment
- correct answer a researcher manipulates or changes a particular variable under controlled conditions
while observing resulting changes in another variable or variables.
Occam's razor
- correct answer maintains that researchers should apply the simplest explanation possible to any set of
observations.
correlation
- correct answer measurement of the strength of the relationship between two variables
reliability
- correct answer if a test produces the same result when researchers administer it to the same group of
people at different times, it has reliability.
