A researcher tests whether a tutoring program improves grades. One group receives tutoring, while the other does not. What is the group that does NOT receive tutoring called?
What is Control Group ?
A researcher wants to test whether music affects memory. However, one group gets 30 minutes to study while the other gets 5 minutes. Why might this study have a validity problem?
The different study times could affect memory scores, making it difficult to determine whether music caused the difference.
A psychologist spends several months studying one person with a rare memory condition in great detail. What research method is this?
What is a case study?
Focuses on how unconscious thoughts, emotions, and early experiences can influence behavior.
What is Psychodynamic Perspective?
A teacher tests whether study time affects quiz scores. What are the IV and DV?
IV = Study time; DV = Quiz scores
Researchers give one group a new energy drink and another group a regular drink. Which group is the experimental group?
What is the group receiving the new energy drink ?
Researchers want to determine whether a new study method improves test scores. Name ONE thing researchers can do to make their conclusion stronger.
Keep conditions similar, use a control group, clearly measure the DV, control outside factors, or use a consistent procedure.
A psychologist watches students during lunch and records how often they interact with their friends without interfering. What research method is being used?
What is observation?
Focuses on free will, personal growth, self-esteem, and reaching one's potential.

IV = Hours of sleep; DV = Memory test score
Researchers want to know whether a new study technique improves test scores. Group A uses the new technique, and Group B continues studying normally. Identify the experimental group and control group.
What is
A strong experiment keeps conditions similar, uses comparison groups, measures the dependent variable correctly, and follows the same procedure. Why are these things important for validity?
They help researchers determine whether the independent variable actually caused the change in the dependent variable.
