1Which research design allows a researcher to manipulate an independent variable to observe its direct cause-and-effect relationship on a dependent variable?
A.Experimental design
B.Quantitative observational design
C.Qualitative design
D.Correlational survey design
Explanation: An experimental design is defined by the researcher directly manipulating the independent variable and randomly assigning participants to control and experimental conditions. This manipulation enables researchers to infer a direct cause-and-effect relationship between variables.
2A researcher collects heart rate measurements in beats per minute from participants before and after a public speaking task. What type of data is being collected?
A.Objective quantitative data
B.Subjective quantitative data
C.Qualitative data
D.Subjective qualitative data
Explanation: Heart rate measured in beats per minute is objective quantitative data because it represents a numerical physiological measurement independent of personal opinion or bias. Physical physiological markers recorded by instruments yield objective quantitative evidence.
3What is the primary ethical purpose of obtaining informed consent before a psychological investigation begins?
A.To ensure participants understand the research nature, risks, and rights before agreeing to join
B.To guarantee that the experimental hypotheses will be supported by participant performance
C.To prevent participants from withdrawing from the study once data collection has started
D.To eliminate the need for debriefing at the conclusion of the research session
Explanation: Informed consent ensures that participants are fully advised of the study's purpose, procedures, potential risks, and rights before voluntary participation. It protects participant autonomy and upholds ethical research standards.
4A study investigates whether listening to classical music improves memory recall in secondary students. What is the independent variable in this investigation?
A.The presence or type of background music being listened to during study
B.The number of words correctly recalled on the memory test
C.The age and grade level of the secondary students
D.The room temperature and lighting during the memory test
Explanation: The independent variable is the condition or factor manipulated or varied by the researcher, which in this study is the background music condition. The effect of this manipulation is measured on the memory recall task.
5Why is random allocation of participants to experimental conditions essential in a true experimental design?
A.It minimizes systematic differences between treatment groups prior to the manipulation
B.It guarantees that the sample size will automatically represent the broader population
C.It eliminates all potential measurement errors during quantitative data collection
D.It allows researchers to avoid obtaining informed consent from participants
Explanation: Random allocation ensures that individual participant characteristics (such as baseline memory capacity or fatigue) are evenly distributed across control and experimental groups. This minimizes confounding participant variables prior to testing.
6A researcher conducts a focus group to explore how adolescents perceive workplace stress. What is a key advantage of using a qualitative design over a quantitative design?
A.It provides rich, in-depth descriptive data explaining the context behind participant attitudes
B.It allows precise statistical generalization to large nationwide populations
C.It completely removes researcher bias during data interpretation and thematic analysis
D.It establishes clear cause-and-effect relationships between workplace variables
Explanation: Qualitative research designs excel at capturing complex personal perspectives, rich context, and nuanced experiences that numerical ratings cannot capture. Open-ended discussion highlights the 'why' and 'how' behind human behavior.
7A psychologist administers the same anxiety questionnaire to a group of participants on two separate occasions two weeks apart and finds highly consistent test scores. What property does this demonstrate?
A.High test-retest reliability
B.High construct validity
C.High ecological validity
D.Low internal consistency
Explanation: Test-retest reliability assesses the consistency of a measuring instrument over time when administered to the same individuals under similar conditions. Highly consistent scores across repeated administrations indicate strong reliability.
8A researcher measures stress levels using self-reported survey ratings on a 1-to-7 scale. Which type of data is produced by this method?
A.Subjective quantitative data
B.Objective quantitative data
C.Subjective qualitative data
D.Objective qualitative data
Explanation: Self-reported survey ratings produce numerical scores based on personal self-perception, making the data subjective quantitative. Numerical rating scales turn individual subjective judgments into quantitative figures.
9In an investigation examining sleep deprivation and reaction time, all participants complete reaction tests in the same quiet, temperature-controlled room at 9:00 AM. What role do these fixed conditions play?
A.Controlled extraneous variables
B.Independent variables
C.Dependent variables
D.Confounding participant variables
Explanation: Holding environmental conditions constant across all participants converts potential extraneous variables into controlled variables. This prevents room temperature or noise from confounding the relationship between sleep deprivation and reaction time.
10A study measures reaction time in milliseconds using an electronic timer that consistently reads 50 milliseconds slower than the true response time. How does this systematic instrument error impact validity and reliability?
A.Reliability remains high, but internal validity is reduced
B.Both reliability and internal validity are severely reduced
C.Internal validity remains high, but reliability is reduced
D.Neither reliability nor internal validity is affected
Explanation: Systematic measurement errors consistently shift all readings in the same direction, maintaining high test-retest reliability across repeated trials. However, because the recorded times do not accurately reflect true reaction times, internal measurement validity is compromised.
