d) Theories are always completely correct
b) Data do not equal facts.
Two researchers observe the same classroom but draw different conclusions about student engagement based on their prior beliefs. This highlights that:
a) Observations are purely objective.
b) Observations are influenced by prior knowledge and judgments.

A scientific theory is later revised because new data show flaws in its assumptions. Which principle does this reflect?
a) Theories are always wrong but can be partially correct.
b) Data equal facts.
c) Science is fully objective.
d) Observations are free from bias
a) Theories are always wrong but can be partially correct.
A researcher observes that 50 children improve memory after drinking green tea and concludes, “Green tea always improves memory.” Which principle is this an example of?
a) Deduction
b) Inductivism
c) Falsificationism
d) Rationalism
B) Inductivism
Which of the following illustrates falsificationism?
a) A scientist keeps testing a theory only to find more confirming cases.
b) A scientist designs an experiment to see if her theory can be disproven.
c) A philosopher claims that “all human behavior can be explained by reason alone.”
d) A researcher assumes that observing enough cases will establish a universal law.
b) A scientist designs an experiment to see if her theory can be disproven.
Why is it impossible to confirm a scientific theory by inductivism alone?
a) Theories allow an infinite number of predictions, and not all can be confirmed.
b) Theories are purely logical and need no data.
c) Observations are always subjective.
d) A single falsification makes the theory true
a) Theories allow an infinite number of predictions, and not all can be confirmed.
A scientist proposes that “all swans are white.” Later, she discovers a black swan. According to Popper’s suggestion, this means:
a) The theory is strengthened by further testing.
b) The theory remains valid because most swans are white.
c) The theory is falsified and must be rejected or modified.
d) The theory can still be confirmed with more white swans
c) The theory is falsified and must be rejected or modified.
Falsificationism is considered a stricter method of testing because:
a) It requires infinite observations to confirm laws.
b) It focuses on refuting predictions rather than confirming them.
c) It assumes theories can never be wrong.
d) It eliminates all subjectivity from observations
b) It focuses on refuting predictions rather than confirming them.
A researcher gives one group of students caffeine before a test and another group no caffeine, while keeping all other conditions constant. The test performance is then measured. In this study, the independent variable (IV) is:
a) Test performance
b) Amount of caffeine given
c) The test questions
d) Number of students in each group
b) Amount of caffeine given
A researcher gives one group of students caffeine before a test and another group no caffeine, while keeping all other conditions constant. The test performance is then measured. In this study, the dependent variable (DV) is:
a) Amount of caffeine consumed
b) Test performance (scores)
c) The random assignment of groups
d) The number of test questions
b) Test performance (scores)
Why is it important to apply the ceteris paribus principle in experiments?
a) To manipulate as many variables as possible
b) To keep all other factors constant so only the IV affects the DV
c) To eliminate the need for hypotheses
d) To confirm theories without testing them
b) To keep all other factors constant so only the IV affects the DV
Which of the following is the best example of using the experimental method?
a) Observing classroom behavior without intervention
b) Giving one group a memory-training program and comparing outcomes with a control group
c) Interviewing students about their study habits
d) Reviewing past test records to find patterns
b) Giving one group a memory-training program and comparing outcomes with a control group
Which statement about experiments is most accurate?
a) Experiments only describe relationships but cannot explain them.
b) Experiments allow researchers to test causal hypotheses by manipulating variables.
c) Dependent variables are manipulated, while independent variables are measured.
d) Experiments do not require controlling external factors
b) Experiments allow researchers to test causal hypotheses by manipulating variables.
A researcher wants to study the effect of sleep deprivation on memory. One group of students stays awake for 24 hours, while another group sleeps normally. The group that sleeps normally is the:
a) Independent variable
b) Experimental group
c) Control group
d) Dependent variable
c) Control group
Why is a control group important in experiments?
a) To eliminate the need for hypotheses
b) To provide a baseline for comparison with the experimental group
c) To manipulate the independent variable more effectively
d) To remove the dependent variable from analysis
b) To provide a baseline for comparison with the experimental group
